I. Device Description

A. General

The MAX5309 is a10-bit, eight channel, low-power, voltage-output, digital-to-analog converters (DAC) in a space-

saving 16-pin TSSOP package. The wide +2.7V to +5.5V supply voltage range and less than 215µA (max) supply

current per DAC is excellent for low-power and low-voltage applications. The low 2nV-s glitch energy of the MAX5309

makes it ideal for digital control of fast-response, closed-loop systems.

The MAX5309 has a hardware reset input (CLR-bar) which clears all registers and DACs to zero. The MAX5309 has

a software shutdown feature that reduces the supply current to 1µA. The MAX5308 features a load DAC (LDAC-bar)

function that updates the output of all eight DACs simultaneously.

The 3-wire SPI™, QSPI™, MICROWIRE™ and DSP-compatible serial interface allows the input and DAC registers

to be updated independently or simultaneously with a single software command. This device uses a double-buffered

design to minimize the digital-noise feedthrough from the digital inputs to the outputs. The MAX5309 operating

temperature range is from -40°C to +85°C
