DAC7734EC/1K

Digital To Analog Converters Overview

The DAC7734EC/1K is a quad-channel, 16-bit digital-to-analog converter manufactured by Texas Instruments. It features an R-2R resistor ladder structure and provides buffered voltage outputs. The device operates with dual analog supply voltages of ±15 V and a digital supply of 5 V. Key electrical specifications include a settling time of 10 µs, a sampling rate of 89 kS/s per channel, and a typical power consumption of 50 mW. Non-linearity performance is specified at ±3 LSB for both differential and integral non-linearity, with a gain error of 0.05% FSR. It communicates via a serial interface and is housed in a 48-pin SSOP package.

Digital To Analog Converters Feature Summary

• Integrates four independent 16-bit DAC channels within a single compact package.
• Includes internal output buffers to drive external loads directly without additional amplification stages.
• Supports serial data input with a reset function that returns outputs to mid-scale upon initialization.

Digital To Analog Converters Applications

• Multi-channel process control systems requiring precise analog signal generation.
• Programmable test and measurement equipment needing stable reference voltages.
• Industrial automation interfaces converting digital control signals into analog actuator commands.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'EC/1K' against the manufacturer's current datasheet to confirm packaging format and environmental compliance status. Ensure the ordering part number matches the required tape-and-reel quantity and temperature grade before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a design requires four synchronized 16-bit outputs with low power consumption. Verify that the ±15 V analog supply rails are available in the target system architecture. Confirm that the serial interface timing meets the microcontroller or DSP clock requirements for the desired update rate.

Digital To Analog Converters Part Context

This part belongs to the DAC7734 family of high-resolution digital-to-analog converters. It shares architectural similarities with other members like the DAC7731 but offers multiple channels instead of a single output. The series is designed for applications demanding high accuracy and low noise in industrial environments.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible substitutes within the same family include the DAC7734E. For single-channel applications, the DAC7731EC may serve as a functional alternative if fewer outputs are required. Verify pinout compatibility and thermal characteristics before swapping components.
