RESET
The RESET function can be used either at power-up or at any
time during DAC operation. The RESET function is independent
of CS . This pin is active low and sets the DAC output registers
to either center code for the DAC8412, or zero code for the
DAC8413. The reset-to-center code is most useful when the
DAC is configured for bipolar references and an output of 0 V
after reset is desired.
SUPPLIES
Supplies required are V
be set between −15 V and 0 V. V
operating range is between 5 V and 15 V.

reference input only. It does not supply current to the device. If

does supply currents to the digital outputs when readback is used.
AMPLIFIERS
Unlike many voltage output DACs, the DAC8412 features buffered
voltage outputs. Each output is capable of both sourcing and
sinking 5 mA at ±10 V, eliminating the need for external
amplifiers when driving 500 pF or smaller capacitive load in
most applications. These amplifiers are short-circuit protected.
