DAC7634EBG4

Digital To Analog Converters Overview

The DAC7634EBG4 is a 16-bit, quad voltage-output digital-to-analog converter manufactured by Texas Instruments. It integrates four independent DAC channels within a single SSOP-48 package. The device utilizes an R-2R resistor ladder architecture and accepts serial data inputs. Key electrical specifications include a sampling rate of 89 kS/s per channel, a settling time of 10 µs, and a power consumption of 7.5 mW. It operates on a single 5 V supply with an operating temperature range from -40°C to +85°C. Non-linearity errors are specified at +/- 3 LSB for INL and +/- 2 LSB for DNL.

Digital To Analog Converters Feature Summary

• Integrates four independent 16-bit voltage output channels in a compact surface-mount package
• Features a serial interface compatible with standard communication protocols
• Includes a reset function that returns outputs to mid-scale upon initialization

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable gain amplifier biasing networks
• Multi-axis motion control systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix BG4 indicates lead-free composition and RoHS compliance when sourcing. Confirm the package type matches the SSOP-48 footprint requirements for the target PCB design. Ensure the serial interface timing parameters align with the host microcontroller capabilities before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when four isolated 16-bit analog outputs are required from a single controller. The serial interface reduces pin count compared to parallel alternatives. Verify that the 5 V supply voltage and current drive capabilities meet the load requirements of the downstream circuitry.

Digital To Analog Converters Part Context

This part belongs to the DAC7634 family of quad digital-to-analog converters. The 'E' suffix typically denotes an extended industrial temperature range, while 'BG4' specifies the lead-free SSOP-48 packaging variant. It serves as a high-resolution solution for applications needing multiple synchronized analog signals.

Digital To Analog Converters Replacement Considerations

The DAC7634E is a direct functional equivalent without the specific packaging suffix. Other members of the DAC76xx series may offer different resolutions or channel counts but require interface verification.
