概述

Description

OPA350EA/250 is TI’s single‑channel, low‑power op‑amp designed for battery-powered sensing. It offers rail‑to‑rail input and output for signals near ground or V+, and operates from a single supply (typical range around 2.7–5.5 V). Key benefits are very low quiescent current, low input bias current, and low input offset voltage, plus unity‑gain stability for buffering or simple amplifier configs.
Ideal uses include sensor front ends (thermistors, RTDs, bridge sensors), portable instruments, and ADC front‑ends where power, size, and precision matter. The EA/250 suffix refers to its small-package/temperature grade option.
Notes: ensure inputs stay within the device’s common‑mode range for your supply, provide proper power bypassing, and match the gain/compensation to your bandwidth needs. It’s not intended for very high‑speed or ultra‑high‑precision DC offset applications outside the datasheet specs. For exact numbers (offset, bias, GBW, PSRR, temp range), consult the OPA350 datasheet.

Package

OPA350EA/250 is available in a 5-pin SC70 package (SC70-5), Pb-free.

Pinout

Pin count: 5 pins.
Function: OPA350EA/250 is a single-channel operational amplifier (op-amp) in a SOT-23-5 package, with rail-to-rail input and output, designed for low-power amplification of small analog signals (e.g., sensor front-ends).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, sensors, and embedded processing solutions; one of the world’s largest IC makers.
