DAC7631E/1K

Digital To Analog Converters Overview

The DAC7631E/1K is a single-channel, 16-bit voltage output digital-to-analog converter manufactured by Texas Instruments. It utilizes an R-2R resistor string architecture and features a serial interface for data input. The device operates on a single 5 V supply with a typical power consumption of 1.8 mW. Key electrical specifications include a settling time of 10 µs, a sample rate of 93 kS/s, and a gain error of 0.08% FSR. Non-linearity performance is characterized by a differential non-linearity (DNL) of ±2 LSB and an integral non-linearity (INL) of ±3 LSB. It is housed in a 20-pin SSOP package and supports an operating temperature range from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Integrates a reset function that forces the output to mid-scale upon initialization or command.

Digital To Analog Converters Applications

• Process control systems requiring high-resolution analog signal generation
• Battery-powered instrumentation utilizing low-power serial interfaces
• Industrial automation equipment needing precise voltage references

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm packaging configuration. The '/1K' designation typically indicates tube packaging containing 1000 units, though distributors may list alternative bulk options. Ensure the component meets RoHS compliance requirements for the target market. Cross-reference the full part number with official datasheets to validate pinout and thermal characteristics before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, 16-bit resolution is required with low power consumption. The serial interface reduces pin count compared to parallel alternatives. Verify that the 10 µs settling time and 93 kS/s update rate meet system bandwidth requirements. Confirm compatibility with the host microcontroller's SPI or serial protocol. Ensure the external reference voltage matches the desired output range for optimal accuracy.

Digital To Analog Converters Part Context

This part belongs to the DAC7631 family of serial input digital-to-analog converters. It shares architectural similarities with other members like the DAC7631E but differs in packaging and quantity configurations. The series is designed for applications demanding moderate speed and high resolution with minimal interface complexity. It serves as a cost-effective solution for general-purpose analog output tasks in industrial environments.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include DAC7631EB-1KG4 and DAC7631E-1KG4. These variants maintain identical electrical specifications and pinouts while potentially differing in tape-and-reel packaging or extended temperature ratings. Verify pin compatibility and software register maps before swapping components in existing designs.
