Part Overview
Description
The MAX5721 is a dual 10-bit, low-power, buffered voltage-output digital-to-analog converter (DAC) packaged in a space-saving 8-pin μMAX® package (5mm x 3mm). It operates with a wide supply voltage range of 2.7V to 5.5V and consumes only 112µA of supply current, making it suitable for low-power and low-voltage applications. The DAC outputs employ on-chip precision output amplifiers that swing rail-to-rail. The MAX5721's reference input accepts a voltage range from 0 to VDD. In power-down mode, the reference input is high impedance, further reducing the system's total power consumption.
The 20MHz, 3-wire SPI, QSPI, MICROWIRE™, and DSP-compatible serial interface saves board space and reduces the complexity of opto- and transformer-isolated applications. The MAX5721 on-chip power-on reset (POR) circuit resets the DAC outputs to zero and loads the output with a 100k resistor to ground, providing additional safety for applications that drive valves or other transducers that need to be off on power-up. The MAX5721's software-controlled power-down reduces supply current to less than 0.3μA and provides software-selectable output loads (1kΩ, 100kΩ, or high impedance) while in power-down. The MAX5721 is specified over the -40°C to 125°C automotive temperature range.
Features
Ultra-low power consumption: 112μA at VDD = 3.6V, 135μA at VDD = 5.5V
Tiny 8-pin μMAX package
0.3μA power-down current
Guaranteed 10-bit monotonicity (±1LSB DNL)
Safe power-up reset to zero volts at DAC output
Three software selectable power-down impedances (100kΩ, 1kΩ, Hi-Z)
Fast 20MHz, 3-wire SPI, QSPI, and MICROWIRE-compatible serial interface
Rail-to-rail output buffer amplifiers
Schmitt-triggered logic inputs for direct interface to optocouplers
Wide -40°C to 125°C operating temperature range
Automatic tuning: gain and offset adjustment, power amplifier control
Applications
Process control
I/O boards
Battery-powered instruments
VCO control
