The TSB572 and TSB611 single op amps are the first devices produced using ST’s new 40V-ready BiCMOS semiconductor process. This technology delivers superior GBW/Icc efficiency resulting in about five times lower supply current in relation to performance, compared with standard op amps. In addition, low input-offset voltages with temperature drift below 6µV/°C simplify system design, […]

Bipolar Junction Transistor with really tight tolerance on hFE – Do you know of a BJT with a really tightly […]
Unity-gain difference amp precisely level shifts and buffers small difference signals, rejects up to ±270 V common mode
Linear Technology introduces the LT6375, a unity-gain difference amplifier with integrated precision matched resistors, which precisely level shifts and buffers small difference signals while rejecting up to ±270V common mode. The A-grade version achieves unprecedented performance: CMRR is 97dB (min), initial gain error is 35ppm (max), gain drift is 1ppm/°C (max) and gain nonlinearity is […]

Common emitter non-symmetrical gain – I have simulated in LTspice a very simple CE amplifier. There is no AC capacitor at the emitter It is a plain and simple CE emitter bias unbypassed with a gain of Av = -Rc / RE = 4.07. It turns out that, as input is a perfect 1V sine […]
New digital power amplifiers for car audio deliver Cleaner Sound and Simplify System Design
STMicroelectronics (NYSE: STM), is extending its lead in digital automotive-audio technologies by launching a second generation of power amplifiers that simplify design for car-radio system suppliers and deliver better listening experiences to drivers and passengers – even in smaller cars. ST’s new, second-generation FDA801 and FDA801B 4-channel class-D[1] amplifiers with digital input convert the digital […]
Audio op amp puts out 150 mW
Texas Instruments introduced an audio operational amplifier (op amp) that sets the latest standard in audio performance. The OPA1622 is the newest addition to the company’s Burr-Brown™ Audio line and is the next generation of the widely adopted OPA1612. The new OPA1622 delivers high output power of up to 150 mW and extremely low distortion […]

Why is unloaded buffer showing an offset? – I am using an AD8041 IC as a buffer for a 0.2 Vpp sinewave input at 1 kHz from the function generator. The circuit is set on an NI Elvis II+ board. The buffer is unloaded but there occurs some offset at the output of the buffer. […]
VCM vs VOUT plots for instrumentation amplifiers with two op amps
This article introduces the VCM vs. VOUT plot for an instrumentation amplifier with two operational amplifiers (op amps) and delivers a thorough treatment of this amplifier topology. Additionally, the internal node equations are derived and used to plot each internal amplifier’s input common-mode and output-swing limits as a function of the instrumentation amplifier’s common-mode voltage. […]
Economical coax-packaged RF amps cover 9 kHz to 3 GHz
Pasternack, a provider of in-stock and ready to ship RF, microwave and millimeter wave products, announces the release of new affordable coaxial-packaged RF amplifiers. Both low noise and gain block amplifiers are offered and display excellent performance covering wide octave frequency bands from 9 KHz to 3 GHz. All of these new amplifiers from Pasternack […]
