MCP3465RT-E/SFX

Analog To Digital Converters (ADC) Overview

The MCP3465RT-E/SFX is a 16-bit Delta-Sigma Analog-to-Digital Converter (ADC) from Microchip Technology, housed in a 12-lead UQFN package. It supports one differential or two single-ended input channels with a programmable data rate up to 153.6 ksps and gain ranging from 0.33x to 64x. Key electrical specifications include a typical offset error drift of 4/Gain nV/°C, low noise of 2.3 µV RMS at Gain = 16x, and an internal 2.4V voltage reference with 15 ppm/°C drift. The device operates with AVDD between 2.7V and 3.6V and DVDD between 1.8V and 3.6V, featuring ultra-low full shutdown current consumption below 2.4 µA.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity by checking the marking on the 2 mm x 2 mm x 0.55 mm 12-Lead UQFN package against official Microchip documentation. Confirm that the ordering suffix 'E' indicates compliance with RoHS standards and the 'SFX' denotes the specific UQFN package variant. Ensure supply chain sources provide valid certificates of conformity and traceability records consistent with Microchip Technology Inc. manufacturing protocols.

Analog To Digital Converters (ADC) Selection Notes

Select this ADC when high precision is required with minimal external components due to integrated references and oscillators. Consider the 153.6 ksps maximum data rate and programmable gain for applications needing flexibility in signal conditioning. Evaluate power constraints, noting the ultra-low shutdown current, and ensure the system supports the required AVDD and DVDD voltage ranges. The internal sequencer is beneficial for reducing MCU load in multi-channel scanning applications.

Analog To Digital Converters (ADC) Part Context
