Product Details

The AD5790 is a single 20-bit, voltage out DAC that operates from a bipolar supply up to 33V. Reference buffers are also provided on-chip The AD5790 accepts a positive reference input in the range of 5V to VDD – 2.5V and a negative reference input in the range of VSS + 2.5v to 0V. The AD5790 offers a relative accuracy of +/-2 LSB's max and operation is guaranteed monotonic with a -1 LSB to +3 LSB's DNL specification.

The part uses a versatile 3-wire serial interface that operates at clock rates 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 the DAC output powers up to 0V and 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.

Tools & Simulations

Precision DAC Error Budget Tool

The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
