Overview

The MAX5825BAUP+ is an ultra small, octal channel, 12bit buffered output digital to analogue converter (DAC) in 20 pin TSSOP package. This low power, voltage output DAC includes output buffers and an internal 3ppm/°C reference that is selectable to be 2.048V, 2.500V or 4.096V. It accepts wide supply voltage range of 2.7V to 5.5V with extremely low power of 6mW consumption to accommodate most low voltage applications. A precision external reference input allows rail to rail operation and presents 100Kohm load to an external reference. The DAC output is buffered and has low supply current of less than 250µA per channel and low offset error of ±0.5mV. The device has watchdog function which can be enabled to monitor the I/O interface for activity and integrity. The MAX5825BAUP+ is typically used in programmable voltage and current sources, gain and offset adjustment, power amplifier control and biasing, servo loops, automatic tuning and optical control.
