Low-Power, Dual, 12-Bit Voltage-Output DACs

_______________General Desc ription
The MAX5156/MAX5157 low-power, serial, voltage-out-
put, dual 12-bit digital-to-analog converters (DACs)
consume only 500μA from a single +5V (MAX5156) or
+3V (MAX5157) 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 MAX5156/MAX5157 provide a programmable
logic output pin for added functionality, and a serial-
data output pin for daisy chaining.
