DAC61401RTER

Digital To Analog Converters Overview

The DAC61401RTER is a single-channel, 12-bit buffered high-voltage output digital-to-analog converter (DAC) from Texas Instruments. It features an integrated 2.5V precision internal reference with 10ppm/°C drift and guarantees monotonic operation with less than 1LSB maximum INL/DNL. The device supports wide power supply ranges of +4.5V to +41.5V for unipolar mode and ±4.5V to ±21.5V for bipolar mode, offering 14 user-programmable output ranges including ±20V and 0V to 40V. Communication is handled via a 50MHz 4-wire SPI-compatible interface with readback and daisy-chain capabilities. It operates over a temperature range of –55°C to +125°C and is housed in a 16-pin WQFN package.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'RTER' corresponds to the 16-pin WQFN package configuration when sourcing components. Confirm that the required operating voltage levels for AVDD and IOVDD align with the system design constraints before finalizing procurement. Ensure compliance with RoHS standards as indicated in the manufacturer documentation.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high-voltage analog outputs with precise calibration needs. The integrated reference eliminates external component requirements, simplifying board layout. Consider the thermal resistance characteristics of the WQFN package if high ambient temperatures are expected. Verify that the 50MHz SPI interface speed meets the system's data throughput requirements.

Digital To Analog Converters Part Context

This part belongs to the DACx1401 family, which includes the 16-bit DAC81401 variant. Both devices share pin compatibility and similar functional blocks but differ in resolution. The DAC61401 provides 12-bit accuracy suitable for general-purpose high-voltage applications, while the DAC81401 offers higher precision for demanding measurement tasks.

Digital To Analog Converters Replacement Considerations

The DAC81401 serves as a direct pin-compatible upgrade for higher resolution needs. For lower resolution requirements, verify compatibility with other single-channel DACs from the manufacturer, ensuring interface and voltage specifications match.
