MCP3461R-E/ST

Analog To Digital Converters (ADC) Overview

The MCP3461R-E/ST is a single-channel, 16-bit Delta-Sigma Analog-to-Digital Converter (ADC) manufactured by Microchip Technology. It features a programmable data rate up to 153.6 ksps and analog gain settings ranging from 0.33x to 64x. The device operates with an analog supply voltage (AVDD) of 2.7V to 3.6V and a digital supply voltage (DVDD) of 1.8V to 3.6V. Key performance metrics include a typical Signal-to-Noise and Distortion Ratio (SINAD) of 97.2 dB at 4800 SPS with Gain = 1x, and low noise of 2.3 µV RMS at 16x gain. It integrates an internal 2.4V voltage reference, temperature sensor, and burnout current sources.

Analog To Digital Converters (ADC) Feature Summary

• Single differential or two single-ended input channels
• Integrated 2.4V voltage reference with 15 ppm/°C drift
• Advanced security features including 16-bit CRC for SPI communications and register map locking

Analog To Digital Converters (ADC) Applications

• Precision Sensor Transducers and Transmitters
• Factory Automation and Process Controls
• Portable Instrumentation
• Temperature Measurements

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. The 'E' suffix typically denotes RoHS compliance, while '/ST' indicates the TSSOP package variant. Ensure compatibility with system power supplies and SPI interface timing requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the MCP3461R-E/ST when a single-channel high-precision ADC is required. Compare against MCP3462R and MCP3464R if multiple input channels are needed. Consider the UQFN package option if board space is limited, as the TSSOP package has larger thermal resistance characteristics. Verify that the required oversampling ratio and gain settings meet the application's noise and speed constraints.

Analog To Digital Converters (ADC) Part Context

The MCP3461R-E/ST belongs to the MCP3461/2/4R family of 16-bit Delta-Sigma ADCs. This family shares core architectural features such as the internal sequencer, burnout detection, and advanced security registers. The MCP3461R specifically provides one differential or two single-ended inputs, distinguishing it from the dual-channel MCP3462R and quad-channel MCP3464R variants within the same series.
