CLC420
High-Speed, Voltage Feedback Op Amp
General Description
The CLC420 is an operational amplifier designed for applica-
tions requiring matched inputs, integration or transimped-
ance 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 cur-
rent 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 rejec-
tion ratio attractive.
