onsemi Operational Amplifier IC KA2902

The KA2902 is a quad operational amplifier designed for use in a variety of applications, including transducer amplifiers and DC gain blocks. It operates over a power supply range of 3V to 26V (or ¬±1.5V to ¬±13V) and is suitable for both single and split power supply configurations. The device features a large DC voltage gain of 100 dB and an input common mode voltage range that includes ground, making it versatile for different circuit designs. The KA2902 offers a large output voltage swing from 0V to VCC - 1.5V and has a low power drain, which is advantageous for battery-operated devices. It is internally frequency compensated for unity gain, ensuring stable performance across various applications. The operational amplifier is available in both 14-DIP and 14-SOP packages, with an operating temperature range of -40¬8C to +85¬8C, making it suitable for industrial and automotive applications. Engineers considering the KA2902 should note its specifications for input offset voltage, input bias current, and supply current, which are critical for precision applications. The device's thermal resistance and power dissipation ratings also indicate its reliability in demanding environments.
