OP07

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

Short-circuits can cause excessive heating and destructive dissipation. 2. Rth are typical values. 3. Human body model: 100pF discharged through a 1.5kΩ 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 < 5Ω). 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. 3/8 Electrical characteristics OP07 3 Table 2.
