功能描述

The LTC?1282 is a 6μs, 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 1.14μs sample-and-hold, precision reference and internally trimmed clock. Unipolar and bipolar conversion modes provide flexibility for various applications. They are built with LTBiCMOS? 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. The internal clock is trimmed for 6μs maximum conversion time. The clock automatically synchronizes to each sample command eliminating problems with asynchronous clock noise found in competitive devices. A high speed parallel interface eases connections to FIFOs, DSPs and microprocessors.
