CLC420

CLC420 High-Speed, Voltage Feedback Op Amp September 1999 CLC420 High-Speed, Voltage Feedback Op Amp General Description The CLC420 is an operational amplifier designed for applications requiring matched inputs, integration or transimpedance amplification. Utilizing voltage feedback architecture, the CLC420 offers a 300MHz bandwidth, a 1100V/µs slew rate and a 4mA supply current (power consumption of 40mW, ± 5V supplies). Applications such as differential amplifiers will benefit from 70dB common mode rejection ratio and an input offset current of 0.2µA. With its unity-gain stability, 2pA/ current noise and 3µA of input bias current, the CLC420 is designed to meet the needs of filter applications and log amplifiers. The low input offset current and current noise, combined with a settling time of 18ns to 0.01% make the CLC420 ideal for D/A converters, pin diode receivers and photo multipliers amplifiers. All applications will find 70dB power supply rejection ratio attractive.
