TPV721S5 产品概述

TPV721S5 是 TECH PUBLIC(台舟电子)推出的一款单路运算放大器,采用 SOT-23-5 小封装,面向低功耗、低电压和高精度的便携及工业应用。器件支持轨到轨输入与轨到轨输出,单电源工作电压范围宽(2.2V 至 5.5V),在电池供电或 5V 系统中均能提供稳定的放大性能。

一、主要性能特点

  • 单路运算放大器,封装:SOT-23-5,适合表面贴装与空间受限应用。
  • 单电源工作电压:2.2V ~ 5.5V(最大电源差 Vdd‑Vss = 5.5V)。
  • 轨到轨输入与轨到轨输出,最大化动态输入/输出摆幅,利于低电压系统的信号处理。
  • 增益带宽积 (GBP):10 MHz,适用于低至中等闭环增益场合与缓冲应用。
  • 压摆率 (SR):4.5 V/µs,支持较快的瞬态响应。
  • 输出电流能力:最高可达 50 mA,能够驱动中等负载。
  • 静态工作电流 (Iq):约 800 µA,在低功耗应用中有竞争力。

二、精度与噪声指标

  • 输入失调电压 (Vos):典型 5 mV,适合大多数通用精密模拟电路。
  • 输入失调电压温漂 (Vos TC):300 nV/°C,温度稳定性优良。
  • 输入偏置电流 (Ib):约 1 pA,输入电流极低,适合高阻抗传感器接口。
  • 输入失调电流 (Ios):约 1 pA。
  • 噪声密度 (eN):30 nV/√Hz @1 kHz,低噪声特性适合信号调理与前端放大。
  • 共模抑制比 (CMRR):75 dB,抑制共模干扰能力良好。

三、典型应用场景

  • 电池供电的便携设备:传感器信号放大、缓冲、滤波。
  • 工业传感与测量:高阻抗传感器接口(称重、压力、温度传感器等)。
  • 精密缓冲与电压跟随(用于 ADC 前端)。
  • 低噪声前置放大器与差分到单端转换。
  • 小功率驱动任务,需注意输出功率与封装热耗散。

四、使用建议与注意事项

  • 电源去耦:建议在靠近电源引脚处放置 0.1 µF 陶瓷去耦电容,必要时并联 1 µF 或更大电容以稳定低频响应。
  • 输入保护:虽然支持轨到轨输入,但避免输入电压超出电源轨范围(含浪涌),必要时加入限流或钳位元件以防静电或反向注入。
  • 输出驱动:器件可提供最高约 50 mA 输出电流,但在高负载下功耗与结温上升明显,长时间大电流输出时需考虑热设计与散热路径。
  • 布局建议:高阻抗输入应缩短引线并远离高频开关和大电流回路,确保低噪声和低漂移性能。
  • 引脚与封装:SOT-23-5 小封装便于空间受限电路,但请以官方资料为准确认引脚排列与封装尺寸。

五、总结

TPV721S5 在低电压、低功耗条件下提供轨到轨输入/输出、低输入偏置电流、低噪声及良好温漂性能,适合用于便携仪表、传感器接口以及 ADC 前端等对精度与动态范围有要求的应用。设计时结合合适的电源去耦、保护与散热措施,可发挥其稳定、高精度的放大能力。欲了解详细引脚定义、典型应用电路与完整电气特性,请参考 TECH PUBLIC 提供的完整数据手册。

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
