The MAX5322 dual, 12-bit, serial-interface, digital-to-ana-
log converter (DAC) provides bipolar ±5V to ±10V out-
puts from ±12V to ±15V analog power-supply voltages, or
unipolar 5V to 10V outputs from a single 12V to 15V ana-
log power-supply voltage.
The MAX5322 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-shut-
down feature that reduces current consumption to 2.8µA.
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 outputs to 0V. The outputs
can be asynchronously updated with the load DAC
(LDAC) input.
The device features a fast 10MHz SPI™-/QSPI™-
/MICROWIRE™-compatible serial interface that operates
with 3V or 5V logic. Additional features include a serial-
data output (DOUT) for daisy chaining and read-back
functions. The MAX5322 requires external reference volt-
ages of 2V to 5.25V and is available in a 28-pin SSOP
package that operates over the extended (-40°C to
+85°C) temperature range.
