TSV772IST 是一款由 ST(意法半导体)提供的双路运算放大器,突出低噪声、低偏置电流和轨到轨输入/输出能力,适用于对精度与带宽有平衡要求的便携与工业应用。主要参数包括:增益带宽积(GBP)20 MHz,压摆率(SR)13 V/μs,输入失调电压典型 200 μV,输入偏置电流仅 75 pA,输入失调电流 1 pA,噪声密度 7 nV/√Hz(@10 kHz),共模抑制比(CMRR)可达 120 dB。器件为双通道,封装为 MiniSO-8。
封装:MiniSO-8,便于 PCB 密度较高的设计。静态电流(Iq)典型 1.9 mA,输出驱动能力高达 65 mA,可短时驱动较大负载,但建议在连续大电流输出场景下评估热量与功耗。
在高精度或高温环境应用中,应关注偏置与失调随温度的变化,并设计必要的校准或漂移补偿。高阻抗输入路径需严格控制 PCB 清洁度与漏电路径,以发挥 pA 级偏置电流性能。总体而言,TSV772IST 在低电压、低噪声与精密测量场合表现优异,是兼顾带宽与精度的通用双路运放选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
