Low-Power, Low-Glitch, Octal 12-Bit Voltage-
Output DACs with Serial Interface
General Description
The MAX5306/MAX5307 are 12-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 MAX5306/MAX5307 makes
them ideal for digital control of fast-response, closed-
loop systems.
The MAX5306 has a digital output (DOUT) that can be
used for daisy-chaining multiple devices. The MAX5307
has a hardware reset input (CLR) which clears all regis-
ters and DACs to zero. The MAX5306/MAX5307 have a
software shutdown feature that reduces the supply cur-
rent to 1µA. The MAX5306/MAX5307 feature a load
DAC (LDAC) 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 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.
The MAX5306/MAX5307 operating temperature range
is from -40°C to +85°C.
