LTC1277CSW Datasheet PDF - Linear Technology

DESCRIPTION
The LTC®1274/LTC1277 are 8µs sampling 12-bit A/D converters which draw only 2mA (typ) from single 5V or ±5V supplies. These easy-to-use devices come complete with a 2µs sample-and-hold, a precision reference and an internally trimmed clock. Unipolar and bipolar conversion modes add to the flexibility of the ADCs.
