MAX5152/MAX5153
Low-Power, Dual, 13-Bit Voltage-Output DACs
with Configurable Outputs

_______________General Description
The MAX5152/MAX5153 low-power, serial, voltage-out-
put, dual 13-bit digital-to-analog converters (DACs)
consume only 500µA from a single +5V (MAX5152) or
+3V (MAX5153) supply. These devices feature Rail-to-
Rail
® output swing and are available in space-saving
16-pin QSOP and DIP packages. Access to the invert-
ing input allows for specific gain configurations, remote
sensing, and high output current capability, making
these devices ideally suited for industrial process con-
trols. These devices are also well suited for digitally
programmable (4–20mA) current loops.
The 3-wire serial interface is SPI™/QSPI™ and
Microwire™ compatible. Each DAC has a double-
buffered input organized as an input register followed
by a DAC register, which allows the input and DAC reg-
isters to be updated independently or simultaneously.
Additional features include a programmable shutdown
(2µA), hardware-shutdown lockout, a separate voltage
reference for each DAC, power-on reset, and an active-
low clear input (CL) that resets all registers and DACs
to zero. The MAX5152/MAX5153 provide a programma-
ble logic output pin for added functionality, and a seri-
al-data output pin for daisy chaining.
