Description
20-bit, 1 LSB accurate DAC
18-bit, ±1 LSB INL, voltage output DAC ,
buffered reference inputs
18-bit, ±1 LSB INL, voltage Output DAC ,
unbuffered reference inputs
16-bit, ±0.5 LSB INL, voltage Output DAC
16-bit, 1 LSB accurate 5 V DAC
GENERAL DESCRIPTION
that operates from a bipolar supply of up to 33 V. The AD5790
accepts a positive reference input in the range of 5 V to VDD
2.5 V and a negative reference input in the range of VSS + 2.5 V
to 0 V. The AD5790 offers a relative accuracy specification of
±2 LSB maximum range, and operation is guaranteed mono-
tonic with a 1 LSB to +3 LSB DNL 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.
Reference buffers are also provided on chip. The part incorpo-
rates a power-on reset circuit that ensures 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 a disable feature that places the output in a
defined load state. The part provides an output clamp feature
that places the output in a defined load state.
