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.
