DAC1220E/2K5

Digital To Analog Converters Overview

The DAC1220E/2K5 is a single-channel, 20-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes delta-sigma architecture to achieve high resolution with a sampling rate of 500 S/s and a typical settling time of 1.8 ms. The device operates on a single 4.75 V to 5.25 V supply for both analog and digital domains, consuming only 2.5 mW of power. It features an unbuffered voltage output and supports 2-Wire or 3-Wire serial interfaces. Packaged in a 16-SSOP surface-mount case, it includes on-chip offset and gain calibration, ensuring a gain error of 0.015% FSR and integral nonlinearity of +/- 1 LSB across the -40°C to +85°C operating temperature range.

Digital To Analog Converters Feature Summary

• Integrates on-chip offset and gain calibration circuits to maintain high accuracy without external trimming components.
• Employs delta-sigma modulation architecture to deliver 20-bit resolution with low power consumption.
• Supports flexible serial communication through compatible 2-Wire and 3-Wire interface protocols.

Digital To Analog Converters Applications

• High-resolution industrial process control systems requiring precise analog signal generation.
• Battery-powered instrumentation where ultra-low power consumption is critical.
• Precision data acquisition systems needing stable, calibrated analog outputs.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type, as the base part number may correspond to tube packaging while the /2K5 suffix indicates reel packaging. Ensure compatibility with existing serial interface configurations before procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference the manufacturer's latest datasheet to validate current production status and recommended operating conditions.

Digital To Analog Converters Selection Notes

Select this component when 20-bit resolution and low power are prioritized over high-speed conversion. The unbuffered voltage output requires careful consideration of load impedance and potential buffering needs in the final design. Verify that the system clock can support the 500 S/s sampling rate. Compare against other members of the DAC1220 family if different packaging or interface options are required for the specific application constraints.

Digital To Analog Converters Part Context

This device belongs to the DAC1220 series from Texas Instruments, designed for applications demanding high precision and low power. It complements other data converters in the portfolio by offering superior resolution compared to standard 12-bit or 16-bit devices. The series focuses on delta-sigma technology to provide excellent linearity and noise performance suitable for sensitive measurement environments.

Digital To Analog Converters Replacement Considerations

Check for direct pin-compatible upgrades within the DAC1220 family. Verify if alternative packages like the EVM development kit variants offer similar electrical characteristics. Ensure any substitute maintains the same 20-bit resolution and serial interface compatibility to avoid redesigning the PCB layout or firmware drivers.
