MAX5312 Datasheet, PDF (1/19 Pages) Maxim Integrated Products – +-10V, 12-Bit, Serial, Voltage-Output DAC

19-3119; Rev 0; 12/03
±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.
