The GS321B-TR with SOT-23-5 Operational Amplifier ROHS is a single-supply, low-power, high-speed, very low-noise amplifier manufactured by Gainsil. It has a bandwidth of 1MHz and an output range from 0.8V to 5V. The amplifier uses a single external capacitor to set the gain to any value from unity to 55. It also features input offset matching for noise-free bipolar signal operation, low input bias/offset current for superior speed and accuracy, and low supply current consumption for longer battery life. This amplifier is ideal for a variety of applications such as active filters, signal conditioning, audio amplification, and medical instrumentation.
