Operational amplifiers (op amps) have proliferated from specialized instruments made from large tubes to tiny monolithic circuits composed of a sliver of silicon, germanium or gallium arsenide. Dozens ...

Editor’s note: My good friend and long-time colleague, Michael Steffes, expands upon my introduction article, Rauch filter basics, and adds some very useful and practical insights into the Rauch ...

Until now, very high-speed Operational Amplifiers (OP AMPS) have offered a top bandwidth of about a gigahertz. The addition of silicon germanium (SiGe) to a high-speed bipolar-CMOS process results in ...

Four new broadband op-amp chips achieve industry-leading performance levels for driving high-resolution video signals. The ZL40120/21/22/23 chips post high ratings for bandwidth, linearity, and ...

National Semiconductor has added three op amps with voltage feedback and rail-to-rail output options. The LMH6622 has an input voltage noise of 1.6nV per root hertz and input current noise of 1.5pA ...

Linear Tech is aiming at high-impedance sensor transimpedance amplifiers with an op-amp that requires only 3fA of bias current (typical at 25°C) while offering 500MHz gain bandwidth product. Potential ...

Linear has announced two FET-input single and dual op amps for high speed transimpedance amplifier (TIA) and buffer applications. With just 3fA bias current at 25°C and 4pA max over the entire -40 to ...

Holtek has released new 500kHz gain bandwidth product operational amplifier series, the HT9251/52/54. The HT925x series can operate with a 1.8V to 5.5V single power supply and with its 50uA (typ.) ...

As one of the basic building blocks used in an array of consumer, industrial, scientific and other applications, the operation amplifier (op amp) is amongst the most widely used electronic devices.
