Dual Operational Amplifier IC featuring a 1 MHz bandwidth and 1 V/µs slew rate. This voltage-feedback amplifier offers a minimum voltage gain of 25000 and a typical common-mode rejection ratio of 95. Designed for commercial temperature ranges (0°C to 70°C), it operates with a nominal supply voltage of ±15V, with limits up to ±18V. The 8-terminal DIP package houses two independent operational amplifier functions, characterized by a maximum input offset voltage of 7500 µV and low bias current.
