Product Summary
The LTC1273ACSW#PBF is an A/D Converter. The LTC1273ACSW#PBF is 300ksps, sampling 12-bit A/D converters that draw only 75mW from single 5V or ±5V supplies. The LTC1273ACSW#PBF come complete with 600ns sample-and-holds, precision references and internally trimmed clocks. Unipolar and bipolar conversion modes provide flexibility for various applications. The LTC1273ACSW#PBF is built with LTBiCMOSTM switched capacitor technology. The LTC1273ACSW#PBF has 25ppm/℃ (max) internal references. The LTC1273ACSW#PBF converts 0V to 5V unipolar inputs from a single 5V supply. The LTC1273ACSW#PBF convert ±2.5V and ±5V respectively from ±5V supplies. Maximum DC specifications include ±1/2LSB INL, ±3/4LSB DNL and 25ppm/℃ full scale drift over temperature. Outstanding AC performance includes 70dB S/(N + D) and 77dB THD at the Nyquist input frequency of 150kHz. The applications of the LTC1273ACSW#PBF include
