概述

Description

MAX489EESD+T is a dual operational amplifier from Maxim Integrated (now part of Analog Devices). It provides two rail-to-rail input/output op-amps suitable for low-voltage, single-supply circuits. The EESD suffix means enhanced electrostatic discharge protection on the inputs, and +T indicates Tape & Reel packaging for automated assembly.
Key points:
- Dual, general-purpose op-amps with internal compensation
- Low power, suitable for portable/battery-powered applications
- Rail-to-rail input and output
- Typical uses: sensor interfacing, ADC front-ends, signal conditioning, buffering and filtering
How to use:
- Configure in standard op-amp topologies (inverting, non-inverting, buffers) with appropriate feedback networks
Note:
- For exact electrical specs (supply range, gain bandwidth, slew rate, input/output ranges, and thermal data), consult the official datasheet.

Package

8-pin SOIC (SOP-8) package, Tape‑and‑Reel.

Pinout

- Pin count: 8 pins (8-pin package)
- Function: RS-485/RS-422 transceiver (half‑duplex) with driver and receiver. Pins include DI (driver input), DE (driver enable), RO (receiver output), /RE or RE (receiver enable), and bus pins A and B, plus Vcc and GND. ESD-protected variant.

Manufacturer

Manufacturer: Maxim Integrated Products (now part of Analog Devices). Type: a semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (fabless).

Application

MAX489EESD+T is a rugged, ESD‑protected analog switch/multiplexer. Common applications: routing and multiplexing analog signals in data‑acquisition and instrumentation front ends; audio/sensor signal paths; calibration, test fixtures, and signal‑conditioning boards; portable/handheld devices with tight space/power budgets; automotive and industrial equipment requiring robust ESD protection and extended‑temperature operation.
