DAC7641Y

Digital To Analog Converters Overview

The DAC7641Y is a single-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It utilizes a resistor-string architecture and features a serial interface for data input. The device operates on a typical single supply voltage of 5 V, supporting both bipolar and unipolar output polarities with an external voltage reference. Key performance metrics include a conversion rate of 93 ksps, a maximum settling time of 10 µs, and a full-scale error of ±2 mV. Integral nonlinearity is specified at ±4 LSB. The component is housed in a 20-pin SSOP surface-mount 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 suffix 'Y' against the official Texas Instruments datasheet to confirm package type and temperature grade. Ensure compatibility with the system's serial protocol requirements. Confirm that the external reference voltage matches the DAC's input specifications for optimal accuracy.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, 16-bit resolution is required with a serial interface. Compare against the DAC7631E if a parallel or different pin-count interface is preferred. Verify that the 20-pin SSOP package fits the PCB layout constraints and that the 93 ksps update rate meets the application's bandwidth needs.

Digital To Analog Converters Part Context

The DAC7641Y belongs to the DAC76xx series of low-power, 16-bit digital-to-analog converters from Texas Instruments. This series is designed for applications demanding high accuracy and low power consumption. The Y suffix typically denotes a specific package variant, such as the SSOP-20, intended for surface-mount assembly in compact electronic designs.

Digital To Analog Converters Replacement Considerations

The DAC7631E is a related part within the same family but differs in interface type and pin count. Verify electrical compatibility and pinout differences before substitution. No other direct cross-references are confirmed in the provided documentation.
