DESCRIPTION
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 LTBiCMOSTM switched capacitor technology.
