DAC53701DSGRQ1

Digital To Analog Converters Overview

The DAC53701DSGRQ1 is a 10-bit buffered voltage-output digital-to-analog converter from Texas Instruments. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and supports an ambient temperature range of –40°C to +125°C. The device features a PMBus-compatible I2C interface with four configurable device address options. Key electrical specifications include ±1 LSB INL and DNL, a settling time of 8 µs (typical) at 5.5 V, and a low power consumption of 0.2 mA at 1.8 V. It integrates nonvolatile memory for register retention and includes an internal reference.

Digital To Analog Converters Feature Summary

• Integrates user-programmable nonvolatile memory to save and recall all register settings without software.
• Supports programmable waveform generation including square, triangular, and sawtooth waveforms.
• Features a general-purpose input (GPI) that enables hardware-based function triggering.
• Provides pulse-width modulation output capability using the triangular waveform and feedback pin.

Digital To Analog Converters Applications

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'DSGRQ1' against the manufacturer's official documentation to confirm package type and automotive qualification status. Ensure the component meets the required environmental operating conditions and interface compatibility before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a 10-bit resolution with buffered voltage output is required in a compact form factor. Consider the integrated nonvolatile memory and GPI capabilities if system-level control without a microprocessor is desired. Verify that the I2C interface speed requirements align with standard, fast, or fast mode plus operations.

Digital To Analog Converters Part Context

This part belongs to the DACx3701 family, which also includes the 8-bit DAC43701 variant. Both devices share pin compatibility and feature sets, differing primarily in resolution. The Q1 suffix indicates automotive qualification under AEC-Q100 standards, suitable for demanding vehicle environments.

Digital To Analog Converters Replacement Considerations

The DAC43701 is a pin-compatible alternative within the same family offering 8-bit resolution. Verify functional requirements to ensure the lower resolution meets application needs before substitution.

Digital To Analog Converters FAQ

What is the maximum capacitive load supported by the DAC53701?

The device supports a capacitive load of up to 1 nF with infinite resistive load and 2 nF with a 5 kΩ resistive load, maintaining a phase margin of 30 degrees.

How does the GPI pin function enhance system design?

The General-Purpose Input allows for hardware-based function triggering, enabling features like waveform generation or alarm tones without requiring continuous software intervention.
