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.  
o Eight Highly Integrated 10-Bit DACs in 16-Pin  
TSSOP (6.4mm 5mm) Package  
o Ultra-Low Glitch Energy <2nV-s  
o Low Total Supply Current:  
1.7mA (max) with V  
= V  
= +5.5V

o +2.7V to +5.5V Wide Single-Supply Range  
o Fast 5µs Settling Time  
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.
