本文介绍一组Burr-Brown公司(简称B—B公司)的新产品,它们主要用于仪器仪表中。 INA111仪表放大器 IN111是高性能高速FET输入仪表放大器。该器件采用了电流反馈拓扑技术及激光处理,有极好的性能。它的特点是:FET输入,即I_R=200pA(最大);高速,即T_s为4μs(G=100,0.01％);失调电压低,为500μV(最大);失调电压漂移小,为5μV/℃(最大);共模抑制比高,为106dB(最小)。 IN111有8脚DIP封装及SOL—16贴片式封装两种形式。外加一个电阻(R_G)可使IN111的增益从1改变到
This article describes a set of new products from Burr-Brown, Inc. (B-B), used primarily in instrumentation. INA111 Instrumentation Amplifier The IN111 is a high performance, high speed FET input instrumentation amplifier. The device uses current feedback topology and laser processing, with excellent performance. Its characteristic is: FET input, namely I_R = 200pA (maximum); High speed, namely T_s is 4μs (G = 100, 0.01%); Offset voltage is low, it is 500μV (maximum); Offset voltage drift is small, it is 5μV / ℃ (Maximum); common mode rejection ratio of 106dB (minimum). IN111 8-pin DIP package and SOL-16 chip package in two forms. An additional resistor (R_G) changes the gain of IN111 from 1 to
