DAC7642VFBRG4

Digital To Analog Converters Overview

The DAC7642VFBRG4 is a dual-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It features two independent voltage outputs and operates with a single +5V digital supply and dual ±5V analog supplies. The device utilizes an R-2R resistor ladder architecture to achieve high precision. Key electrical specifications include a maximum sampling rate of 100 ksps, a settling time of 10 µs, and a power consumption of 2.5 mW. It supports SPI-compatible serial interfaces for data input and control. The component is housed in a 32-pin LQFP package and is rated for operation within a temperature range of -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the complete part number including the RG4 suffix against official Texas Instruments documentation to confirm RoHS compliance and lead-free status. Ensure that the specific package variant matches the design footprint requirements. Cross-reference the datasheet revision date to confirm compatibility with existing firmware and hardware designs. Confirm availability through authorized distributors as this component may have limited stock or be subject to long lead times depending on current market conditions.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 16-bit precision is required with low power constraints. Compare against the DAC7642 standard version to verify if the RG4 suffix offers specific environmental or packaging benefits. Consider the 10 µs settling time and 100 ksps speed for application timing requirements. Evaluate the need for buffered outputs versus unbuffered alternatives like the DAC7632 if lower cost is prioritized over drive strength.

Digital To Analog Converters Part Context

The DAC7642 series belongs to Texas Instruments' portfolio of precision digital-to-analog converters. The VFBRG4 designation indicates a specific tape-and-reel packaging variant compliant with environmental standards. This model is part of a broader family that includes single-channel (DAC7641) and quad-channel (DAC7664) variants, offering scalability for different channel count requirements while maintaining consistent performance characteristics across the series.

Digital To Analog Converters Replacement Considerations

The DAC7642VFBT is a compatible alternative from the same manufacturer. Verify pinout compatibility and electrical parameter equivalence before substitution. Check for any differences in packaging or environmental certifications between the RG4 and VFBT suffixes.
