功能描述

The LTC1427-50 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. The LTC1427-50 communicates with external circuitry by using the SMBus serial interface. It acts as an SMBus slave device using one of four selectable SMBus addresses set by the two address pins AD0 and AD1 . On power-up, the DAC output assumes midrange or zero scale, depending on the logic state of the two address pins. The LTC1427-50 can be shut down through the SHDN pin or by setting the SHDN bit = 1 in the SMBus command byte. Digital data for the DAC output is retained internally and the supply current drops to 10µA typically when in shutdown. The LTC1427-50 is available in an 8-pin SO package.
