Description
AD5781
18-bit, 0.5 LSB INL, voltage output DAC
GENERAL DESCRIPTION
The AD57911 is a single 20-bit, unbuffered voltage-output DAC
that operates from a bipolar supply of up to 33 V. The AD5791
accepts a positive reference input in the range 5 V to VDD − 2.5 V
and a negative reference input in the range VSS + 2.5 V to 0 V.
The AD5791 offers a relative accuracy specification of ±1 LSB
max, and operation is guaranteed monotonic with a ±1 LSB
DNL maximum specification.
The part uses a versatile 3-wire serial interface that operates at
clock rates up to 35 MHz and that is compatible with standard
SPI, QSPI™, MICROWIRE™, and DSP interface standards. The
part incorporates a power-on reset circuit that ensures the DAC
output powers up to 0 V and 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.
