High output power operational amplifier

High frequency MEMS testing Recently, a laboratory consulted about high-frequency MEMS testing, which requires sine wave and square wave drive, signal bandwidth up to 7MHz, drive level needs to reach 50Vp-p, and needs to have frequency sweep function and DC+AC working mode. The standard signal generator currently on t

introduction The special requirements of portable audio devices are key to product design. Why is product A better than its competitor, product B, and more desirable to use? Performance-wise, the frequency response flatness and THD+N between competing products are similar, making it difficult to tell which product

This is the circuit design of a 21W Class AB audio amplifier with power transistors as the main part. It is simple in design and also simple to set up. Set the 10k trimmer to about half and the 470 ohm trimmer to 0 resistance. Apply power and set the quiescent current to 30mA by fine tuning the 470 ohm trimmer. Once

　　With the widespread application of integrated operational amplifier parameter testers (hereinafter referred to as op amp testers) in the defense, military and civilian fields, its quality issues are particularly important. Traditional op amp tester calibration solutions can no longer meet the requirements of defense

The following circuit diagram is the schematic diagram of a 1W stereo headphone amplifier. This circuit is built on TDA2822 and is designed for portable players, radios, and other common electronic devices that can use headphones for audio output. A 3V power supply/battery can be used to drive the headpho

　　The popular 555 timer can be used as a PWM/Class D amplifier for musical instruments or other applications. It can operate in a supply voltage range of 4.5V to 16V and can output a drive current of 200mA. The audio signal is sent to the CV (control voltage) pin of the 555 timer. 　　This Design Idea provides two simpl

Keysight Technologies Launches New Solution to Accelerate Digital Pre-distortion Testing of Power Amplifiers • New iterative learning control algorithm reduces power amplifier digital pre-distortion testing time from hours to minutes • Test methods help power amplifier manuf

The MAX2667/MAX2669 high-gain, low- noise amplifiers (LNA) are designed for GPS, Galileo, and GLONASS applications. Designed on Maxim's advanced SiGe process, the devices achieve high gain and the lowest noise figure while maximizing the input-referred 1dB compression point and third-order intercept
