The NCS2561 is a single high speed video driver including a 2-pole reconstruction filter and SAG-correction capability. The NCS2561 is available in a space-saving SC-88 package optimized for low voltage, portable applications. It is designed to be compatible with the Digital-to-Analog (DAC) embedded in most video processors. The NCS2561 internally integrates an 8-MHz 2-pole video DAC reconstruction filter with a fixed gain of 2. The NCS2561 also has a built in SAG-correction circuit when used at the output in an AC-coupled mode. To further reduce power consumption, an enable pin is provided.

The NCS2563 is a 3-channel high speed video amplifier with 6th order Butterworth High Definition (HD) reconstruction filters and 6 dB gain. All three channels can accommodate all Component and RGB video signals. All channels can accept DC- or AC-coupled signals. If AC-coupled, the internal clamps are employed. The outputs can drive both AC- and DC-coupled 150 Ohm loads. It is designed to be compatible with most Digital-to-Analog Converters (DAC) embedded in most video processors.

The NCS2584 is a 4 channel high speed video driver with 6th order Butterworth Reconstruction filters on each channel. A first set of 3 channels has High Definition (HD) 34 MHz filters, one per channel. A fourth channel offers an extra driver for Cvbs type video signal with an 8 MHz filter. The NCS2584 is in fact a combination of a triple HD video driver plus a single Cvbs video driver. In addition, this four channel video driver integrates an auto shutdown function in order to detect the moment when the DAC is turned on or off. It also embeds a load detection to lower the power consumption when the TV is unplugged. To further reduce the layout and software complexity, the NCS2584 will automatically turn off without any external command. These features help significantly the systems like Blu-Ray players or Set Top Boxes to be in line with the restricting energy saving standards on standby modes. It is designed to be compatible with Digital to Analog Converters (DAC) embedded in most video processors. All channels can accept DC or AC coupled signals. In case of AC coupled inputs, the internal clamps are enabled. The outputs can drive both AC and DC coupled 150 ohms loads but also two loads of 150 ohms in parallel.

The NCS29001 is an integrated LED driver used in LCD display backlighting applications. A configurable bill of materials allows the designer to create a highly efficient solution for a variety of LCD screen sizes. The NCS29001 uses a boost type converter to deliver constant current in a string of LEDs. High accuracy PWM dimming is supported for a frequency up to 500 Hz . The integrated soft start function provides excellent control during the power up sequence to avoid current overshoot. The device protects against output overvoltage, open and short LED, and thermal overload. The NCS29001 is offered in the cost effective SOIC14 package.

The NCS325 is a CMOS operational amplifier providing precision performance. The Zero−Drift architecture allows for continuous auto−calibration, which provides very low offset, near−zero drift over time and temperature, and near flat 1/f noise at only 35 µA (max) quiescent current. These benefits make it ideal for precision DC applications. The NCS325 provides rail−to−rail input and output performance and is optimized for low voltage operation as low as 1.8 V and up to 5.5 V. The NCS325 is available in the space saving SOT23−5 package.

The NCS333 is a precision op amp with very low input offset voltage (10 µV max) and near−zero drift over time and temperature. This high precision, low quiescent current amplifiers has high impedance inputs with a common−mode range 100 mV beyond the rails as well as rail−to−rail output swing within 50 mV of the rails. The NCS333 features a wide supply range from 1.8 V to 5.5 V (±0.9 V to ±2.75 V for dual supplies). The NCS333 family exhibits outstandingCMRR without the crossover associated with traditional complementary input stages. This design results in superior performance for driving analog−to−digital converters (ADCs) without degradation of differential linearity. The NCS333 is available in compact SC70−5 and SOT23−5 packages and are specified for operation from −40°C to +105°C. The NCV333 is the automotive qualified version available in SOT23−5 and specified for operation from −40°C to +125°C.Product Family:

The NCS3402 is a nano-power comparator consuming only 470 nA per channel supply current, which make this device ideal for battery power and wireless handset applications. The NCS3402 has a minimum operating supply voltage of 2.7 V over the extended industrial temperature range (TA = -40°C to 125°C), while having an input common-mode range of -0.1 to VCC + 5 V. The ultra low supply current makes the NCS3402 an ideal choice for battery powered and portable applications where quiescent current is the primary concern. Reverse battery protection guards the amplifier from an over-current condition due to improper battery installation. For harsh environments, the inputs can be taken 5 V above the positive supply rail without damage to the device.

Each cell in the battery pack is monitored for an over−voltage and under−voltage condition.Upon detecting an over−voltage, the ODI pin will assert indicating a fault condition and stay asserted until the fault is cleared. During an under voltage condition, the UDI pin will also assert indicating the fault but will have a pulse width that ispre−set in the protector. Both over and under voltage detections have a hard coded pre−set delay time before fault indication.Pulling the ENB high will start a measurement of the battery pack voltage which will be compared to a pre−set detection threshold table.If a threshold voltage is exceeded the protector will power the corresponding LED to indicate state of charge of the pack.Hardware protection and battery monitoring run autonomously and allows operation without a microcontroller.

The NCS36000 is a fully integrated mixed-signal CMOS device designed for low-cost passive infrared controlling applications. The device integrates two low-noise amplifiers and a LDO regulator to drive the sensor. The output of the amplifiers goes to a window comparator that uses internal voltage references from the regulator. The digital control circuit processes the output from the window comparator and provides the output to the OUT and LED pin.
