Overview

The LTC®1427-50 is a micropower, 10-Bit current output DAC with an output range of 0µA to 50µA. The DAC output is guaranteed monotonic and DNL is less than 0.9LSB under all operating conditions. Full-scale accuracy is ±2.5% over the commercial temperature range. The LTC1427-50 operates with power supply voltages from 2.7V to 5.5V and the DAC current source output can be biased from (VCC – 1.3V) to –15V.
