概述

Description

MCP3461RT-E/NC is Microchip Technology’s single‑channel, 12‑bit analog‑to‑digital converter (ADC) with a SPI‑like serial interface. It’s aimed at low‑power, embedded sensing where a microcontroller reads a precise analog signal. Key features typically include 12‑bit resolution, low power consumption, programmable data rate and conversion modes (single‑shot and continuous), and selectable reference options (internal/external). The RT‑E/NC suffix indicates RoHS‑compliant packaging with extended temperature range and a No Connect (NC) pin configuration used for certain package options. Suitable for automotive, industrial, and portable instruments, it can be paired with various sensors (thermistors, pressure sensors, etc.) in compact designs. For exact electrical characteristics, timing, and programming commands, consult Microchip’s MCP3461 data sheet and the ordering guide.

Features

Key features of MCP3461RT-E/NC (concise):
- 12-bit SAR ADC with 4 multiplexed inputs (single-ended or differential)
- SPI-compatible serial interface (CS, SCK, SDI/SDO)
- Single-supply operation: 2.7 V to 5.5 V
- Low power with selectable data rate and low-power modes
- Supports external reference input (and typical internal reference options depend on variant)
- Differential and single-ended input support for flexible sensing
- Extended temperature version: -40°C to +125°C (RT)
- 8-pin package, RoHS-compliant; /NC indicates a no-connect pin
- Suitable for battery-powered and instrumentation applications
Note: For exact electrical specs (data rates, input range, reference details), refer to the official datasheet.

Package

8-pin MSOP package (MSOP-8), RoHS-compliant/lead-free variant.

Pinout

8 pins. It’s a 12-bit ADC with a SPI-compatible serial interface. Pin functions (typical):
- AIN: analog input
- VREF: reference input
- VDD: supply
- GND: ground
- CS: chip select
- SCK: serial clock
- DIN (SDI): data in
- DOUT (SDO): data out
(Used for single-ended analog input with external reference.)

Manufacturer

- Manufacturer: Microchip Technology Inc.
- What kind of company: An American multinational semiconductor company that designs, develops, and markets microcontrollers, mixed-signal/analog ICs, memory, and related products.

Application

Low-power data acquisition for battery-powered devices; sensor interfaces (temp, pressure, humidity, gas, current/voltage) in industrial, automotive and consumer electronics; portable instrumentation and handheld meters; IoT/smart-sensor nodes; medical and environmental monitoring; lab/test equipment and process control.
