COS724TR 产品概述

COS724TR 是 COSINE(科山芯创)推出的一款高性能四路运算放大器,针对便携式仪器、传感器前端和精密信号调理应用进行了优化。器件具有轨到轨输入与输出、低噪声、超高共模抑制能力以及宽电源电压范围,适合对精度和动态性能均有要求的系统。

一、主要特性

  • 四路单芯片运算放大器,封装:TSSOP-14
  • 共模抑制比(CMRR):125 dB(高抑制能力,适合差分测量)
  • 噪声密度(eN):12 nV/√Hz @ 1 kHz(低噪声设计,利于低信号幅值放大)
  • 轨到轨输入、轨到轨输出(减小电源头部空间要求)
  • 增益带宽积(GBP):10 MHz;压摆率(SR):7.5 V/µs(中等带宽与较好瞬态响应)
  • 输入失调电压(Vos):600 µV;温漂(Vos TC):2 µV/℃(保证长期精度)
  • 输入偏置电流(Ib):2.5 pA,输入失调电流(Ios):2.5 pA(适合高阻抗源)
  • 静态电流(Iq):650 µA;输出电流:21 mA(可驱动常见负载)
  • 电源范围:单电源 2.1 V ~ 5.5 V;双电源 -1.05 V ~ 2.75 V

二、典型性能与优势

COS724TR 将低噪声(12 nV/√Hz)、高 CMRR(125 dB)与极低输入偏置(pA 级)结合,特别适合微伏级信号测量与高阻抗传感器接口。轨到轨输入/输出使其在低电压单电源系统中仍能获得较大动态范围。10 MHz 的增益带宽积与 7.5 V/µs 的压摆率,能在中等增益下提供稳定的带宽与快速的瞬态响应。

三、典型应用场景

  • 传感器前端:温度、压力、应变片等高阻抗传感器信号调理
  • 数据采集与采样保持放大器驱动:低噪声和高 CMRR 有利于 ADC 精度提升
  • 便携式医疗与分析仪器:低电源电压与轨到轨特性支持电池供电系统
  • 有源滤波、差分放大器与精密积分器等模拟电路

四、设计与使用建议

  • 电源去耦:建议在 VDD 与 VSS(或 VCC/VEE)靠近引脚处并联 0.1 µF 与 1 µF 陶瓷电容以降低供电噪声;大电容用于稳态滤波。
  • 输入保护与泄漏控制:由于输入偏置电流为 pA 级,PCB 需保持清洁,避免焊剂残留;高阻抗节点可考虑使用防潮涂层或隔离。
  • 布局注意:关键信号走线短而粗,模拟地采用单点回流或星形接地以减小共模干扰;差分信号对称布线。
  • 负载驱动:器件可输出高达 21 mA,驱动能力足以驱动多数采样电路和小功率负载;若驱动大电流负载,请关注热耗散与压摆限制。
  • 带宽与稳定性:GBP 为 10 MHz,适合中等增益应用;高增益时须注意相位裕度与补偿,必要时在反馈回路中加入小电容进行稳定。

五、封装与采购信息

COS724TR 采用 TSSOP-14 封装,适合空间受限的 PCB 设计。器件来自 COSINE(科山芯创),面向需要低噪声、高精度与轨到轨功能的多通道模拟系统。选型时请参考具体器件数据手册以获取完整的温度特性、引脚说明及典型电路应用图。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
