GENERAꢀ DESCRIPTION

The AD5790¹is a single 20-bit, unbuffered voltage-output DAC

that operates from a bipolar supply of up to 33 V. The AD5790

PRODUCT HIGHꢀIGHTS

1. 20-bit resolution.

accepts a positive reference input in the range of 5 V to V_DD

−

2. Wide power supply range of up to 1ꢁ.5 V.

3. −40°C to +125°C operating temperature range.

4. ꢀow 8 nV/√Hz noise.

2.5 V and a negative reference input in the range of V_SS+ 2.5 V

to 0 V. The AD5790 offers a relative accuracy specification of

2 ꢀSB maximum range, and operation is guaranteed mono-

tonic with a −1 ꢀSB to +3 ꢀSB DNꢀ specification.

5. ꢀow 0.018 ppm/°C gain error temperature coefficient.

COMPANION PRODUCTS

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.

Output Amplifier Buffer: AD8ꢁ75, ADA4898-1, ADA4004-1

External Reference: ADR445

DC-to-DC Design Tool: ADIsimPower™
