LTC1282BCN

Analog To Digital Converters (ADC) Overview

The LTC1282BCN is a 12-bit successive approximation analog-to-digital converter featuring an integrated sample-and-hold circuit and precision reference. It operates from a single 3V or dual ±3V supply, consuming 12mW at a throughput rate of 140ksps with a maximum conversion time of 6µs. The device supports unipolar (0V to 2.5V) and bipolar (±1.25V) input ranges. Key electrical specifications include ±0.5LSB integral nonlinearity, ±0.75LSB differential nonlinearity, 69dB signal-to-noise plus distortion ratio, and 77dB total harmonic distortion at the Nyquist frequency.
