Diodes Incorporated is addressing the need for advanced signal conditioning in modern automotive designs by introducing two precision operational amplifiers (op-amps) aimed at different signal frequency scenarios. The low signal-to-noise ratio characteristics of the DIODES AS2376Q mean it is optimized for high-frequency use, such as in onboard chargers (OBCs), DC-DC converters, battery-management system (BMS) implementations,…

STMicroelectronics has added the TSV782 high-performance dual op-amp to its 5V family, with 30MHz gain bandwidth (GBW) and 50µV (typical) input offset voltage for high-speed, high-accuracy signal conditioning. With the ability to function with a supply as low as 2.0V, the TSV782 can operate from a deeply discharged battery and so extend the runtime of equipment such…

The STMicroelectronics TSB582 dual high-output amplifier simplifies circuitry for driving inductive and low-ohmic loads like motors, valves, and rotary resolvers in industrial applications and automotive systems such as steer-by-wire and auto-parking. The TSB582 operates from 4 to 36V supplies and contains two operational amplifiers (op amps), each capable of sinking/sourcing up to 200mA. This enables direct connection…

With a slew rate of 13V/µs, 7nV/√Hz input noise density,…

 This project based on op amp comparator circuit demonstrates the principle of operation of op amp (operational amplifier) as comparator. A comparator [[wysiwyg_imageupload::]]compares two voltages fed to it and gives output correspondingly. This circuit finds application as intermediate circuit in numerous circuits where there is need to compare two voltages. This Op amp comparator circuit project uses opamp (IC LM324) as comparator.  The output of the comparator is high if voltage at positive end is more than voltage at negative end and gives low output if voltage at positive end is lesser than negative end. Read more to find out how this op-amp comparator circuit works and how it can be constructed in an efficient manner.
