Maxim MAX5713/14/15 Quad-Channel, 12-Bit DAC
Maxim Integrated MAX5713/14/15 Quad-Channel, 12-Bit Digital-to-Analog converter (DAC) is a feature-rich device including output buffers and an internal reference that is selectable to 2.048V, 2.500V, or 4.096V. MAX5713/14/15 DAC accepts a wide supply voltage range of 2.7V to 5.5V with extremely low power (3mW) consumption to accommodate most low-voltage applications. A precision external reference input allows rail-to-rail operation and presents a 100kΩ (typ) load to an external reference. The MAX5713/14/15 includes a 50MHz 3-wire SPI/QSPI™/MICROWIRE®/DSP-compatible serial interface that also includes an active-low RDY output for daisy-chain applications. 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, MAX5713/14/15 resets 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. MAX5713/14/15 allow simultaneous output updates using software LOAD commands or the hardware load DAC logic input (active-low LDAC).
