DAC7611PG4

Digital To Analog Converters Overview

The DAC7611PG4 is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder architecture with a buffered voltage output capable of swinging from -2.5 V to +2.5 V. The device utilizes a 3-wire serial interface compatible with standard SPI and QSPI protocols. Key electrical specifications include a settling time of 10 microseconds and a maximum sampling rate of 132 kS/s. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an industrial temperature range from -40°C to +85°C. The component is housed in an 8-pin PDIP package.

Digital To Analog Converters Procurement Notes

Verify the specific suffix PG4 indicates the lead-free PDIP-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the ordering part number matches the required package style and environmental specifications for your manufacturing line.

Digital To Analog Converters Selection Notes

Select this component for applications requiring a single-channel, low-power 12-bit voltage output. Verify that the 132 kS/s update rate meets system timing requirements. Consider the PDIP-8 package constraints if surface-mount technology is preferred for the final assembly. Compare against higher-resolution alternatives if greater precision is necessary.

Digital To Analog Converters Part Context

This device belongs to the DAC761x family of precision digital-to-analog converters. It shares architectural similarities with other members like the DAC7612 and DAC7614, which offer dual and quad channel configurations respectively. All variants utilize the same serial interface protocol and R-2R architecture, facilitating pin-compatible upgrades for multi-channel designs.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes include the DAC7611U (SOIC-8 package) and DAC7611IP (PDIP-8 package). Verify pinout compatibility and package dimensions before substitution. Higher resolution options such as the DAC7612 may require circuit adjustments due to different channel counts.
