The LTC1282 is a 6s, 140ksps, sampling 12-bit A/D converter that draws only 12mW from a single 3V or dual 3V supply. This easy-to-use device comes complete with 1.14s sample-and-hold, precision reference and internally trimmed clock. Unipolar and bipolar conversion modes provide flexibility for various applications. They are built with LTBiCMOSTM switched capacitor technology. The LTC1282 has a 25ppm/C (max) internal reference and converts 0V to 2.5V unipolar inputs from a single 3V supply. With 3V supplies its input range is 1.25V with two's complement output format. Maximum DC specifications include 0.5LSB INL, 0.75LSB DNL and 25ppm/C full-scale drift over temperature. Outstanding AC performance includes 69dB S/(N + D) and 77dB THD at the Nyquist input frequency of 70kHz.
