Description
20-bit, 2 LSB accurate DAC
20-bit, 1 ppm accurate DAC
18-bit, 0.5 LSB accurate DAC
16-bit, 1 LSB accurate 5 V DAC
16-bit, 0.5 LSB accurate DAC
GENERAL DESCRIPTION
that operates from a bipolar supply of up to 33 V. The AD5780
accepts a positive reference input range of 5 V to VDD 2.5 V
and a negative reference input range of VSS + 2.5 V to 0 V. Both
reference inputs are buffered on chip and external buffers are
not required. The AD5780 offers a relative accuracy specifica-
tion of ±1 LSB maximum range, and operation is guaranteed
monotonic with a ±1 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.
PRODUCT HIGHLIGHTS
1. True 18-bit accuracy.
2. Wide power supply range of up to ±16.5 V.
3. 40°C to +125°C operating temperature range.
4. Low 8 nV/√Hz noise.
5. Low ±0.018 ppm/°C gain error temperature coefficient.
