MAX5312

±10V, 12-Bit, Serial, Voltage-Output DAC

EVAALVUAAILTAIOBNLEKIT

±10V, 12-Bit, Serial, Voltage-Output DAC

General Description

The MAX5312 12-bit, serial-interface, digital-to-analog

converter (DAC) provides bipolar ±5V to ±10V outputs

from ±12V to ±15V power-supply voltages, or a unipo-

lar 5V to 10V output from a single 12V to 15V power-

supply voltage.

The MAX5312 features excellent linearity with both inte-

gral nonlinearity (INL) and differential nonlinearity (DNL)

guaranteed to ±1 LSB (max). The device also features

a fast 10µs to 0.5 LSB settling time, and a hardware-

shutdown feature that reduces current consumption to

3.5µA. The output goes to midscale at power-up in

bipolar mode (0V), and to zero scale at power-up in

unipolar mode (0V). A clear input (CLR) asynchronously

clears the DAC register and sets the output to 0V. The

output can be asynchronously updated with the load

DAC (LDAC) input.

The device features a 10MHz SPI™-/QSPI™-/

MICROWIRE™-compatible serial interface that oper-

ates with 3V or 5V logic. Additional features include a

serial-data output (DOUT) for daisy chaining and read-

back functions. The MAX5312 requires a 2V to 5.25V

external reference voltage and is available in a 16-pin

SSOP package that operates over the extended -40°C

to +85°C temperature range.
