DAC1220E

Digital To Analog Converters Overview

The DAC1220E is a single-channel, 20-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes delta-sigma architecture to achieve high resolution with low power consumption of 2.5 mW. The device operates on a single 5V supply, accepting analog and digital voltages between 4.75 V and 5.25 V. It features an unbuffered voltage output and supports 2-Wire or 3-Wire serial interfaces. Key performance metrics include a sampling rate of 500 S/s, a settling time of 1.8 ms, and a gain error of 0.015% FSR. Integral nonlinearity is specified at +/- 1 LSB. The component is housed in a 16-SSOP package and functions within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix when purchasing, as packaging options such as tubes or reels may vary. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly line. Ensure the selected variant matches the required interface protocol and output configuration for your design.

Digital To Analog Converters Selection Notes

Select this component when a single channel with 20-bit resolution is required. Consider the unbuffered voltage output type; external buffering may be necessary if driving low-impedance loads. Verify that the 500 S/s sampling rate meets system timing constraints. Check thermal management needs given the operating temperature range and power specifications.
