COS2333SRA 产品概述
一、产品简介
COS2333SRA 是科山芯创（COSINE）推出的一款双路精密运算放大器，针对低功耗、低噪声与高精度测量场景优化设计。器件支持轨到轨输入和轨到轨输出，工作在宽电源范围内，适用于低电压单电源与微型化电池供电系统。
二、主要参数
- 共模抑制比（CMRR）：120 dB
- 噪声密度（eN）：70 nV/√Hz @ 1 kHz
- 输入/输出：轨到轨输入、轨到轨输出
- 单电源工作范围：1.8 V ～ 5.5 V
- 双电源工作范围：±0.9 V ～ ±2.75 V（最大电源差5.5 V）
- 输入失调电压（Vos）：5 µV，温漂（Vos TC）：5 nV/℃
- 输入偏置电流（Ib）：25 pA；输入失调电流（Ios）：10 pA
- 增益带宽积（GBP）：350 kHz；压摆率（SR）：0.2 V/µs
- 静态电流（Iq）：18 µA；输出电流：7 mA
- 放大器数：双路；封装：SOP-8；工作温度：-40 ～ +125 ℃
三、性能优势
COS2333SRA 在低电压及低功耗条件下仍保持优异的直流精度与低噪声特性。120 dB 的高 CMRR 与极低的输入失调（5 µV）使其在差分测量、传感器前端放大等对精度要求高的场合表现出色。70 nV/√Hz 的低噪声与350 kHz 的带宽平衡了信号纯净度与响应速度，18 µA 的典型静态电流有利于电池供电设计延长寿命。
四、典型应用场景
- 精密差分/仪表放大器前端
- 电池供电的便携式测量仪器、医疗设备模拟前端
- 传感器接口（温度、压力、应变片放大）
- 数据采集系统的缓冲放大与滤波器
- 工业控制与低频信号处理电路
五、封装与选型建议
COS2333SRA 采用 SOP-8 封装，便于双路放大器在有限空间内集成。对于高精度应用，建议搭配低漂移电阻和良好电源去耦，布局时将模拟信号线与噪声源分离，并在输入端加入合适的滤波与保护器件以避免同相/差分输入超出范围。

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
