LTC1428-50 Micropower 8-Bit Current Sink Output D/A Converter FEATURES s s s s s s s DESCRIPTION The LTC ®1428-50 is a micropower 8-bit current sink output D/A converter (DAC) with an output range of 0µA to 50µA. In 3.3V or 5V systems, the DAC IOUT pin can be biased from 2V to 10V. Supply current is only 130µA. Shutdown mode drops the supply current to 0.2µA. The LTC1428-50 communicates with external circuitry by using one of three interface modes: standard 3-wire serial mode or one of two pulse modes. Upon power-up, the internal counter resets to 10000000B, the DAC output assumes midrange and the chip configures to 3-wire or pulse mode depending on the CS signal level. In 3-wire mode, the system MPU can serially transfer 8-bit data to and from the LTC1428-50.
