GENERAꢀ DESCRIPTION

The AD5780¹is a true 18-bit, unbuffered voltage output DAC

that operates from a bipolar supply of up to 33 V. The AD5780

accepts a positive reference input range of 5 V to V_DD− 2.5 V

and a negative reference input range of V_SS+ 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.

PRODUCT HIGHꢀIGHTS

1. True 18-bit accuracy.

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

External Reference: ADR445

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.

DC-to-DC Design Tool: ADIsimPower™
