100MHz, High Input Impedance, Very Wideband, Uncompensated Operational Amplifiers

HA-2620/2625 are bipolar operational amplifiers that feature very high input impedance (500M?, HA-2620) coupled with wideband AC performance. The high resistance of the input stage is complemented by low offset voltage (0.5mV, HA-2620) and low bias and offset current (1nA, HA-2620) to facilitate accurate signal processing. Input offset can be reduced further by means of an external nulling potentiometer. The 100MHz gain bandwidth product (HA-2620/2625 are stable for closed loop gains greater than 5), 35V/μs slew rate and 150kV/V open loop gain enables

HA-2620/2625 to perform high gain amplification of very fast, wideband signals.
