GENERAL DESCRIPTION

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

that operates from a bipolar supply of up to 33 V. The AD5760

AD5760 offers a relative accuracy specification of ±0.5 LSB

maximum range, and operation is guaranteed monotonic with a

±0.5 LSB DNL maximum range specification.

The part uses a versatile 3-wire serial interface that operates at

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

SPI, QSPI™, MICROWIRE™, and DSP interface standards. The

part 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 part provides an output clamp feature that

places the output in a defined load state.
