Overview

The MAX5815BAUD+ is an ultra small, quad channel, 12bit buffered output digital to analogue converter (DAC) with internal reference and I2C interface in 14 pin TSSOP package. The DAC include output buffers and an internal reference that is selectable to be 2.048V, 2.500V or 4.096V. A precision external reference input allows rail to rail operation and presents a 100Kohm (typ) load to an external reference. It has an I2C compatible, 2-wire interface that operates at clock rates up to 400KHz. The DAC output is buffered and has a low supply current of less than 250µA per channel and a low offset error of ±0.5mV (typ). On power-up, the device reset the DAC outputs to zero, providing additional safety for applications that drive valves or other transducers which need to be off on power-up. The internal reference is initially powered down to allow use of an external reference.
