GENERAL DESCRIPTION

The AD57601 is a true 16-bit, unbuffered voltage output digital-

to-analog converter (DAC) that operates from a bipolar supply

of up to 33 V. The AD5760 accepts a positive reference input

range of 5 V to VDD − 2.5 Vand a negative reference input range

of VSS + 2.5 V to 0 V. The AD5760 offers a relative accuracy

specification of ±0.5 LSB maximum range, and operation is

guaranteed monotonic with a ±0.5 LSB differential nonlinearity

(DNL) maximum range specification.

The device uses a versatile 3-wire serial interface that operates

at clock rates of up to 35 MHz and is compatible with standard

serial peripheral interface (SPI), QSPI™, MICROWIRE™, and

DSP interface standards. The device incorporates a power-on

reset circuit that ensures that the DAC output powers up to 0 V

in a known output impedance state and remains in this state

until a valid write to the device takes place. The device provides

an output clamp feature that places the output in a defined load

state.
