MCP4726A0T-E/CH

Digital To Analog Converters Overview

The MCP4726A0T-E/CH is a single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features an integrated nonvolatile EEPROM for data retention and utilizes a two-wire I2C serial interface. The device operates on a single supply voltage ranging from 2.7V to 5.5V and supports Standard (100 kHz), Fast (400 kHz), and High-Speed (3.4 MHz) communication modes. Key electrical specifications include a typical settling time of 6 µs, a maximum INL error of ±2 LSB, and a DNL error of ±0.2 LSB. It is housed in a compact 6-lead SOT-23 package and is qualified for automotive applications under the AEC-Q100 standard.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile EEPROM retains DAC register settings and configuration bits during power-off conditions.
• Rail-to-rail buffered analog output amplifier ensures full-scale signal swing capability.
• Configurable power-down modes allow system current reduction with selectable output pull-down resistors.
• Supports external reference voltage selection with programmable unity or 2x output gain options.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration and signal conditioning
• Low-power portable instrumentation
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the component authenticity through authorized Microchip distributors or certified suppliers. Confirm that the part number matches the specific suffix requirements for your application environment. Ensure compliance with RoHS directives and relevant automotive qualification standards before integration into production designs.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, high-resolution digital-to-analog conversion is required within a minimal footprint. The inclusion of onboard EEPROM eliminates the need for external memory components to maintain state across power cycles. Consider the extended temperature range and low power consumption characteristics for battery-operated or harsh environment deployments.

Digital To Analog Converters Part Context

This device belongs to the MCP47X6 family of voltage output DACs, which also includes the 8-bit MCP4706 and 10-bit MCP4716 variants. All members share identical pinouts, interfaces, and core functionalities, differing primarily in resolution. This specific model represents the highest precision option within the series, offering 12-bit accuracy for demanding analog signal generation tasks.

Digital To Analog Converters Replacement Considerations

Direct functional replacements within the same family include the MCP4706A0T-E/CH and MCP4716A0T-E/CH. These parts offer identical pinouts and interfaces but provide lower resolution (8-bit and 10-bit respectively). Verify that the reduced resolution meets the specific accuracy requirements of the target application.
