DAC43204RTER

Digital To Analog Converters Overview

The DAC43204RTER is an 8-bit, quad-channel digital-to-analog converter featuring buffered voltage and current outputs. It operates within a supply voltage range of 1.7 V to 5.5 V and supports an ambient temperature range from -40°C to +125°C. The device integrates an internal reference and automatically detects I2C, PMBus, or SPI interfaces. Key electrical specifications include 1 LSB INL and DNL for both voltage and current modes. Voltage output settling time is 20 µs, while current output settling time reaches 60 µs. Power consumption varies by mode, with normal operation drawing up to 200 µA per channel in ±250 µA current mode.

Digital To Analog Converters Feature Summary

• Programmable voltage or current outputs with flexible configuration options including gain settings and output ranges.
• Automatic detection of I2C, PMBus, or SPI interfaces simplifies system integration.
• Built-in nonvolatile memory (NVM) enables processor-less applications and design reuse.
• Supports predefined waveform generation such as sine, triangular, and sawtooth waves.

Digital To Analog Converters Applications

• Rack server voltage margining and scaling
• Optical module biasing and calibration
• Inter-DC interconnect metro applications
• High performance computing systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'RTER' corresponds to the WQFN-16 package and reel packaging format. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the component matches the required 8-bit resolution variant within the DACx3204 family.

Digital To Analog Converters Selection Notes

Select this model when 8-bit resolution is sufficient for the application requirements. Consider the DAC53204 for 10-bit precision or the DAC63204 for 12-bit accuracy if higher linearity is needed. Verify that the 1 LSB INL/DNL specification meets the system's error budget constraints.

Digital To Analog Converters Part Context

This component belongs to the Texas Instruments DACx3204 family, which includes pin-compatible 12-bit (DAC63204), 10-bit (DAC53204), and 8-bit (DAC43204) variants. All members share identical functionality regarding interface detection, GPIO configuration, and NVM features, differing primarily in resolution and associated static performance metrics.

Digital To Analog Converters Replacement Considerations

The DAC53204RTER and DAC63204RTER are pin-compatible replacements offering higher resolutions. For lower resolution needs, the DAC43204RTET serves as an alternative package option within the same series.
