DAC7614E

Digital To Analog Converters Overview

The DAC7614E is a quad, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features four buffered voltage outputs and utilizes an R-2R resistor ladder architecture. The device operates with a single 5V analog supply and a 5V digital supply. Key electrical specifications include a settling time of 10 microseconds, a sampling rate of 89 kS/s, and a power consumption of 15 mW. Linearity performance is defined by a differential nonlinearity of ±1 LSB and integral nonlinearity of ±2 LSB. The component is housed in a 20-pin SSOP package and supports serial interface communication.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

Verify the specific suffix designation when ordering, as packaging options such as tape-and-reel variants exist. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected package variant matches the PCB footprint requirements. Cross-reference the manufacturer part number against current distributor listings to confirm active availability and lead times.

Digital To Analog Converters Selection Notes

Select this component when a design requires multiple synchronized analog outputs from a single controller without external multiplexing. The 12-bit resolution balances cost and precision for general-purpose applications. Consider the 10us settling time against system update rates. Verify that the serial interface timing aligns with the host processor's clock capabilities and voltage levels.

Digital To Analog Converters Part Context

This device belongs to the DAC7614 family of quad digital-to-analog converters. It serves as a legacy alternative to newer high-speed or higher-resolution models.
