DAC7614U/1K

Digital To Analog Converters Overview

The DAC7614U/1K is a quad, 12-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture and operates with a serial interface compatible with standard protocols. The device requires a single 5 V analog supply and a separate 5 V digital supply. Key electrical specifications include a settling time of 10 µs, a sampling rate of 89 kS/s, and a typical power consumption of 15 mW. Nonlinearity performance is specified at +/- 2 LSB for integral nonlinearity (INL) and +/- 1 LSB for differential nonlinearity (DNL). The component is housed in a 20-pin SSOP package and supports operation within a temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels within a single compact package.
• Features a reset function that returns all outputs to mid-scale upon initialization.
• Utilizes an R-2R resistor ladder structure for stable voltage conversion.
• Supports serial data input for efficient microcontroller interfacing.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable gain amplifier circuits
• Portable instrumentation with battery-powered constraints

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix '/1K' confirms the reel packaging format containing 1000 units per reel. Ensure the base part number matches the SSOP-20 package variant rather than other pin-compatible options like the SOIC-16 or tube-packaged versions. Confirm RoHS compliance status through the manufacturer's official documentation before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when four isolated 12-bit voltage outputs are required with low power consumption. The 10 µs settling time suits applications needing moderate update rates up to 89 kS/s. Verify that the 5 V supply requirement aligns with the system design, as this model does not support lower voltage rails compared to other series variants.

Digital To Analog Converters Part Context

This part belongs to the DAC761x family of precision digital-to-analog converters from Texas Instruments. The 'U' suffix indicates the SSOP-20 surface-mount package, while '/1K' denotes the tape-and-reel quantity. It shares architectural similarities with the DAC7613 and DAC7615 but differs in channel count and package configuration.

Digital To Analog Converters Replacement Considerations

The DAC7614E/1K serves as a direct replacement with identical electrical characteristics but utilizes an SSOP-20 package instead of the standard SOIC variant. Other family members like the DAC7615 offer similar performance in different package formats.
