DAC1221E

Digital To Analog Converters Overview

The DAC1221E is a single-channel, 12-bit digital-to-analog converter manufactured by Burr-Brown. It accepts parallel binary input data and produces an analog output voltage. The device operates with a maximum linear error of 0.018% and features a settling time of 7 microseconds. It supports multiple input codes including binary, offset binary, and two's complement binary. The component is housed in a 28-lead plastic dual in-line package (PDIP) and requires power supplies of +5V and ±12V or ±15V. The analog output range spans from -10V to +10V.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation as Burr-Brown or Texas Instruments depending on the production era. Confirm the package type is PDIP-28. Check for RoHS compliance status as older versions may not meet current environmental standards. Ensure supply voltages match the specific variant requirements.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution with parallel interface is required. Consider the 7us settling time for speed constraints. Verify that the 28-pin DIP footprint fits the PCB layout. Compare against serial alternatives like the DAC7611 if pin count reduction is necessary.

Digital To Analog Converters Part Context

This part belongs to the Burr-Brown family of high-performance analog converters. It serves as a bridge between digital processing units and analog actuators or sensors. The device represents standard industry solutions for mid-resolution conversion tasks before higher integration levels became common.

Digital To Analog Converters Replacement Considerations

Direct replacements include the DAC7621E which shares similar specifications. Verify pin compatibility and electrical parameters before substitution. Other variants in the DAC12xx series may offer different packaging or speed characteristics.
