The TLV1562 is a 10-bit CMOS low-power, high-speed programmable resolution analog-to-digital converter based on a low-power recyclic architecture. The unique architecture delivers a throughput up to 2 MSPS (million samples per second) at 10-bit resolution. The programmable resolution allows a higher conversion throughput as a tradeoff of lower resolution. A high speed 3-state parallel port directly interfaces to a digital signal processor (DSP) or microprocessor (uP) system data bus. D0 through D9 are the digital output terminals with D0 being the least significant bit (LSB). The TLV1562 is designed to operate for a wide range of supply voltages (2.7 V to 5.5 V) with very low power consumption (11 mA maximum at 5.5 V, 10 MHz CLKIN). The power saving feature is further enhanced with a software power-down feature (1 uA maximum) and auto power-down (1 uA maximum) feature. Many programmable features make this device a flexible general-purpose data converter. The device can be configured as either four single-ended inputs to maximize the capacity or two differential inputs to improve noise immunity. The internal system clock (SYSCLK) may come from either an internally generated OSC or an external clock source (CLKIN). Four different modes of conversion are available for different applications. The interrupt driven modes are mostly suitable for asynchronous applications, while the continuous modes take advantage of the high speed nature of a pipelined architecture. A pair of built-in sample-and-hold amplifiers allow simultaneous sampling of two input channels. This makes the TLV1562 perfect for communication applications. Conversion is started by the RD\ signal, which can also be used for reading data, to maximize the throughput. Conversion can be started either by the RD\ or CSTART\ signal when the device is operating in the interrupt-driven modes. The dedicated conversion start pin, CSTART\, provides a mechanism to simultaneously sample and convert multiple channels when multiple converters are used in an application. The converter incorporates a pair of differential high-impedance reference inputs that facilitate ratiometric conversion, scaling, and isolation of analog circuitry from logic and supply noise. Other features such as low input capacitance (10 pF) and very wide input bandwidth (75 MHz) make this device a perfect digital signal processing (DSP) companion for mobile communication applications. A switched-capacitor design allows low-error conversion over the full operating free-air temperature range. The features that make this device truly a DSP friendly converter include: 1) programmable continuous conversion modes, 2) programmable 2s complement output code format, and 3) programmable resolution.

The TLVx170 family of electromagnetic interference (EMI)-hardened, 36-V, single-supply, low-noise operational amplifiers (op amps) have a THD+N of 0.0002% at 1 kHz and can operate on supplies that range from 2.7 V (±1.35 V) to 36 V (±18V).
