DAC7654YCT

Digital To Analog Converters Overview

The DAC7654YCT is a quad-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture and provides buffered voltage outputs. The device operates with a single +5V digital supply and dual ±5V analog supplies. Key electrical specifications include a settling time of 15µs, a gain error of 0.8% FSR, and an integral nonlinearity (INL) of ±3 LSB maximum. It supports parallel data interfaces and functions within a temperature range of -40°C to +85°C. The component is housed in a 64-LQFP package.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent 16-bit DACs in a single package.
• Integrated reset function that returns outputs to mid-scale upon power-up or reset assertion.
• Buffered voltage output stage designed for direct driving of external loads without additional amplification.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation.
• Programmable logic controller (PLC) analog output modules.
• Test and measurement equipment needing precise multi-point voltage references.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'YCT' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as manufacturing processes may update over time. Check for obsolescence notices, as this component has been identified as discontinued in some distributor catalogs. Ensure the source document explicitly lists the DAC7654YCT part number to avoid confusion with similar variants like the DAC7654YT.

Digital To Analog Converters Selection Notes

Select this component when a design requires four synchronized 16-bit voltage outputs with moderate speed requirements. The 15µs settling time suits applications where high-frequency sampling is not critical. Verify that the system can accommodate the required dual ±5V analog supply rails alongside the single 5V digital supply. Consider the 64-LQFP footprint during PCB layout planning to ensure adequate thermal dissipation and pin access.

Digital To Analog Converters Part Context

This part belongs to the DAC7654 family of quad-channel converters from Texas Instruments. It serves as a higher-resolution alternative to 12-bit devices in the same series. The YCT suffix typically denotes a specific tape-and-reel packaging option for surface-mount assembly. It shares functional similarities with other quad-channel DACs but distinguishes itself through its specific 16-bit resolution and parallel interface capability.

Digital To Analog Converters Replacement Considerations

The DAC7664YCT is listed as a manufacturer-recommended replacement. Verify pinout compatibility and electrical parameter alignment before substitution. Other family members may require interface modifications due to differing serial or parallel control schemes.
