概述

Description

The MCP6546RT-I/OT is Microchip’s low-power, dual operational amplifier in an 8-pin package, part of the MCP6546 family. It is designed for single-supply operation with rail-to-rail input and output, making it suitable for battery-powered sensor conditioning, buffering, filtering, and general analog amplification tasks.
Key points:
- Dual rail-to-rail I/O op-amp for crowding inputs near ground and Vdd.
- Very low power consumption, ideal for portable/standalone instruments.
- Unity-gain stable and suitable for buffering, summing, and simple amplification stages.
- Industrial-temperature variant and packaging options are indicated by the RT-I/OT suffix (check datasheet for exact temperature range and package details).
For exact electrical specs (supply range, gain bandwidth, input bias, offset, offset drift) and the precise packaging/temperature options, refer to the MCP6546RT datasheet.

Features

MCP6546RT-I/OT features (concise):
- Dual rail-to-rail input/output operational amplifiers.
- Single-supply operation from 2.7 V to 5.5 V.
- Unity-gain stable for buffers and active filters.
- Very low quiescent current per amplifier (low power).
- Low input bias current and low input offset voltage.
- Rail-to-rail output swing near supply rails.
- Industrial temperature range: -40°C to +125°C.
- 8-pin package; packaging variants include -I (industrial temp) and -OT (tape-and-reel).

Package

SC-70-5 (SOT-23-5) package, industrial temperature range (-40°C to +85°C), Tape-and-Reel (OT) packaging.

Pinout

- Pin count: 5 pins (SOT-23-5/SC-70-5 package; RT denotes Tape & Reel packaging)
- Function: Single-channel, low-power operational amplifier with rail-to-rail input and output (RRIO). Pins: V+, V− (or GND), +IN, −IN, OUT.
