19-2151; Rev 0; 8/01
Low-Power, Low-Glitch, Octal 10-Bit Voltage-
Output DACs with Serial Interface
General Description
Features
The MAX5308/MAX5309 are 10-bit, eight channel, low-
power, voltage-output, digital-to-analog converters (DACs)
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 are excellent for low-power
and low-voltage applications. The low 2nV-s glitch energy
of the MAX5308/MAX5309 makes them ideal for digital
control of fast-response, closed-loop systems.

The MAX5308 has a digital output (DOUT) that can be
used for daisy-chaining multiple devices. The MAX5309
has a hardware reset input (CLR) which clears all regis-
ters and DACs to zero. The MAX5308/MAX5309 have a
software shutdown feature that reduces the supply cur-
rent to 1µA. The MAX5308/MAX5309 feature a load
DAC (LDAC) function that updates the output of all
eight DACs simultaneously.
o Software-Selectable Shutdown Mode < 1µA
o 15MHz 3-Wire SPI, QSPI, and MICROWIRE-
Compatible Serial Interface
o Power-Up Reset to Zero Scale
The 3-wire SPI™, QSPI™, MICROWIRE™ and DSP-
compatible serial interface allows the input and DAC
registers to be updated independently or simultaneous-
ly with a single software command. These devices use
a double-buffered design to minimize the digital-noise
feedthrough from the digital inputs to the outputs.
