The DAC-8800 Trim DAC is designed to be a general purpose digitally controlled voltage adjustment device. The output voltage range can be independently set for each set of four D/A converters. In addition, both unipolar and bipolar output voltage ranges are easy to establish by external reference input high and low terminals. The digitally-programed output voltages are ideal for op amp trimming, voltage-controlled amplifier gain setting and any general purpose trimming tasks.

A three-wire serial digital interface loads the contents of eight internal DAC registers which establish the output voltage levels. An asynchronous Clear (CLR) input places all DACs in a zero code output condition, very handy for system power-up. An internal regulator provides TTl input compatibility over a wide range of VDD supply voltages. Single supply operation is available by connecting VSS to GND.

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.
