DAC7731EC/1K

Digital To Analog Converters Overview

The DAC7731EC/1K is a single-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor ladder architecture and features an integrated +10V reference voltage source. The device communicates via a 3-wire serial interface compatible with SPI standards. It operates within a temperature range of -40°C to +85°C and is housed in a 24-pin SSOP package. Key electrical specifications include a maximum gain error of 0.15% FSR, a typical settling time of 3 µs, and a power consumption of 100 mW. The output type is buffered voltage.

Digital To Analog Converters Feature Summary

• Integrates a precision internal reference voltage to reduce external component count.
• Supports standard serial communication protocols for simplified microcontroller interfacing.
• Provides mid-scale reset functionality for predictable system initialization states.

Digital To Analog Converters Applications

• Industrial process control systems requiring precise analog signal generation.
• Data acquisition systems utilizing high-resolution analog outputs.
• Automated test equipment needing stable voltage references.

Digital To Analog Converters Procurement Notes

Verify the specific suffix '1K' indicates reel packaging containing 1000 units as per distributor listings. Confirm RoHS compliance status through the official datasheet before integration. Ensure the SSOP-24 footprint matches the PCB layout requirements. Check for any recent Product Change Notifications (PCN) regarding marking or material changes from Texas Instruments.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 16-bit resolution is required with an internal reference. Compare against the DAC7731E if tape-and-reel packaging is not necessary. Consider the DAC7631 series if lower speed or different pinout configurations are acceptable. Verify that the 3-wire interface aligns with the host controller's available serial ports.

Digital To Analog Converters Part Context

This part belongs to the DAC7731 family of 16-bit voltage-output digital-to-analog converters. It shares architectural similarities with the DAC7631 but offers enhanced performance characteristics such as faster settling times and integrated references. The EC variant denotes specific commercial grade temperature ranges and packaging options within the broader product line.

Digital To Analog Converters Replacement Considerations

The DAC7731E serves as the non-reel version of this component. For pin-compatible alternatives, evaluate the DAC7731EB. Cross-reference with the DAC7631 series only if interface timing and reference requirements allow for architectural differences.
