OP07
Very low offset single bipolar operational amplifier
Features

Extremely low offset: 150V/ max. Low input bias current: 1.8nA LOW Vio drift: 0.5V/C Ultra stable with time: 2V/month max. Wide supply voltage range: 3V to 22V Temperature range: 0C to -105C N DIP8 (Plastic package)
Description
The OP07 is a very high precision op-amp with an offset voltage maximum of 150V. Offering also low input current (1.8nA) and high gain (400V/mV), the OP07C is particularly suitable for instrumentation applications. Pin connections (top view)

1. Short-circuits can cause excessive heating and destructive dissipation. 2. Rth are typical values.
3. Human body model: 100pF discharged through a 1.5k resistor between two pins of the device, done for all couples of pin combinations with other pins floating. 4. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5). Done for all couples of pin combinations with other pins floating. 5. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.
