LM13700M/TR 产品概述

一、产品简介

LM13700M/TR(简称 LM13700)是华冠(HGSEMI)生产的双路可变跨导放大器(Dual Operational Transconductance Amplifier,OTA),封装为 SOP-16,TR 表示带卷盘(Tape & Reel)出货。器件集成了两路跨导单元、线性化二极管以及输出缓冲器,适用于电压—电流可控放大、滤波、振荡与音频处理等需要可变增益的模拟电路。

二、主要电气参数(要点)

  • 放大器数:双路
  • 最大电源宽度 (Vdd - Vss):36 V
  • 单电源工作电压:9.5 V ~ 32 V
  • 双电源工作电压:-16 V ~ +16 V
  • 输入失调电压 (Vos):典型 3 mV
  • 压摆率 (SR):50 V/µs
  • 输入偏置电流 (Ib):8 µA
  • 输入失调电流 (Ios):33 nA
  • 共模抑制比 (CMRR):110 dB
  • 输出电流能力:20 mA(每路)
  • 工作温度范围:0 ℃ ~ +70 ℃

三、典型应用场景

  • 可变频率/可变Q 有源滤波器(如合成器音频滤波)
  • 模拟乘法器、增益控制与自动增益控制(AGC)电路
  • 电压控制振荡器(VCO)与波形整形电路
  • 音频前端放大与动态处理(利用跨导控制实现电压到电流的精确转换)

四、设计与使用建议

  1. 电源与去耦:器件允许较宽电源范围,但最大电源差不能超过 36 V。建议在电源引脚做近端去耦(例如 0.1 µF 陶瓷 + 10 µF 电解)以减少电源噪声对跨导控制的影响。
  2. 控制电流(Iabc):OTA 的跨导由控制电流决定,设计时用稳定电流源或精密电阻设定工作点,以获得线性可控的增益。
  3. 线性化元件:器件内置线性化二极管,合理偏置可提高输入线性度,减小失真,适用于音频应用时效果明显。
  4. 输出缓冲:器件包含输出缓冲器以降低输出阻抗,但仍需注意输出电流上限(20 mA)以及功耗与热限。
  5. 温度与漂移:输入失调电压与偏置电流会随温度变化,关键精度场合建议做温度补偿或使用偏置修正电路。

五、封装与型号说明

  • 型号:LM13700M(SOP-16 封装)
  • /TR 后缀表示卷盘(Tape & Reel)包装,适合表面贴装生产线自动化贴片。
  • 推荐在 PCB 布局时为模拟地与电源地留足回流面积,并将高频去耦放置靠近芯片电源引脚。

六、常见注意事项

  • 不建议超出器件标称的最大电源差与输出电流限制,以免造成永久损坏。
  • 在高增益或低频滚降设计中注意相位裕度与稳定性,必要时加入补偿电容。
  • 工作温度仅覆盖 0~70 ℃,用于更宽温度范围的场合需选用工业级替代型号或额外筛选。

总结:LM13700M/TR 是一款功能齐全且易于使用的双路 OTA,适合对可变跨导、模拟信号处理与音频合成有要求的设计。合理的偏置与电源管理可以发挥其低失调、高 CMRR 与良好带宽/压摆率的优势。

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
