The LT6300 is a 500mA minimum output current, dual op amp with outstanding distortion performance. The amplifiers are gain-of-ten stable, but can be easily compensated for lower gains. The extended output swing allows for lower supply rails to reduce system power. Supply current is set with an external resistor to optimize power dissipation. The LT6300 features balanced, high impedance inputs with low input bias current and input offset voltage. Active termination is easily implemented for further system power reduction. Short-circuit protection and thermal shutdown insure the device's ruggedness.The outputs drive a 100Ω load to ±10.9V with ±12V supplies, and ±10.7V with a 250mA load. The LT6300 is a functional replacement for the LT1739 and LT1794 in xDSL line driver applications and requires no circuit changes.The LT6300 is available in the very small, thermally enhanced, 16-lead SSOP package (same PCB area as the SO-8 package) for maximum port density in line driver applications.ApplicationsHigh Efficiency ADSL, HDSL2, SHDSL Line DriversBuffersTest Equipment AmplifiersCable Drivers

The LT6350 is a rail-to-rail input and output low noise single-ended to differential converter/ADC driver featuring fast settling time. It converts a high or low impedance, single-ended input signal to a low impedance, balanced, differential output suitable for driving high performance differential succesive approximation register (SAR) ADCs. The two op amp topology features very low noise op amps, that can support SNR >110dB in a 1MHz bandwidth.The input op amp is trimmed for constant low input-referred voltage offset over the input range to prevent VOSsteps from degrading distortion.On a single 5V supply, the outputs can swing from 55mV to 4.945V. With the addition of a negative supply, the LT6350 can swing from 0V to 4.945V. Output common mode voltage is set by applying a voltage to the +IN2 pin.The LT6350 draws 4.8mA from a 5V supply and consumes just 60μA in shutdown mode.The LT6350 is available in a compact 3mm × 3mm, 8-pin leadless DFN package and also in an 8-pin MSOP package and operates over a –40°C to 125°C temperature range.Applications16-Bit and 18-Bit SAR ADC DriversSingle-Ended to Differential ConversionDifferential Line Driver

The LT6372-0.2 is a gain programmable, high precision funneling instrumentation amplifier that delivers industry leading DC precision. This high precision enables smaller signals to be sensed and eases calibration requirements, particularly over temperature. The LT6372-0.2 incorporates features into the LT6370 which further improve accuracy and simplify interfacing to an ADC.The LT6372-0.2 uses a proprietary high performance bipolar process which enables industry leading accuracy coupled with exceptional long-term stability. The LT6372-0.2 is laser trimmed for very low input offset voltage (60μV) and high CMRR (80dB, G = 0.2). Proprietary on-chip test capability allows the gain drift (35ppm/°C) to be guaranteed with automated testing.The LT6372-0.2’s difference amplifier uses a split reference configuration which simplifies level shifting the amplifier’s output to the center of the ADC’s input range. Output clamp pins are also provided to limit the voltage which can be applied to an ADC’s input. EMI filtering is integrated on the LT6372-0.2’s inputs to maintain accuracy in the presence of harsh RF interference.The LT6372-0.2 is available in a compact MS16E or a 20-pin 3mm × 4mm QFN. The LT6372-0.2 is fully specified over the –40°C to 85°C and –40°C to 125°C temperature ranges.APPLICATIONSBridge AmplifierData AcquisitionThermocouple AmplifierStrain Gauge AmplifierMedical InstrumentationTransducer InterfacesDifferential to Single-Ended Conversion

The LT6402-20 is a low distortion, low noise differential amplifier/ADC driver for use in applications from DC to 300MHz. The LT6402-20 has been designed for ease of use, with minimal support circuitry required. Exceptionally low input-referred noise and low distortion (with either single-ended or differential inputs) make the LT6402-20 an excellent solution for driving high speed 12-bit and 14-bit ADCs. In addition to the normal unfiltered outputs (+OUT and –OUT), the LT6402-20 has a built-in 75MHz differential low pass filter and an additional pair of filtered outputs (+OUTFILTERED, –OUTFILTERED) to reduce external filtering components when driving high speed ADCs. The output common mode voltage is easily set via the VOCMpin, eliminating an output transformer or AC-coupling capacitors in many applications.The LT6402-20 is designed to meet the demanding requirements of communications transceiver applications. It can be used as a differential ADC driver, a general-purpose differential gain block, or in other applications requiring differential drive. The LT6402-20 can be used in data acquisition systems required to function at frequencies down to DC.The LT6402-20 operates on a 5V supply and consumes 30mA. It comes in a compact 16-lead 3mm × 3mm QFN package and operates over a –40ºC to 85ºC temperature range.ApplicationsDifferential ADC Driver for:ImagingCommunicationsDifferential Driver/ReceiverSingle Ended to Differential ConversionDifferential to Single Ended ConversionLevel ShiftingIF Sampling ReceiversSAW Filter Interfacing/Buffering
