Description

The MAX5717 and MAX5719 are serial-input, unbuffered 16 and 20-bit voltage-output unipolar digital-to-analog converters (DACs) with integrated feedback resistors that allow bipolar operation when used with an external operational amplifier. These DACs provide low glitch energy, low noise, tight bipolar resistor matching, and high accuracy. The DACs feature 1LSB INL (max, MAX5717A) over the temperature range of -40°C to +105°C. Integrated precision setting resistors make the DACs easy to use. The MAX5717 and MAX5719 feature a 50MHz, 3-wire SPI™, QSPI™, MICROWIRE™, and DSP-compatible serial interface.

On power-up, the output resets to zero-scale, providing additional safety for applications which drive valves or other transducers that need to be off on power-up. The DAC output settles in 750ns and has a low offset and gain drift of ±0.1 ppm/°C of FSR.

The MAX5717 is functionally similar to the MAX542, but with significantly faster settling time. The MAX5719 provides a similar speed improvement as well as an increase in resolution to 20 bits.
