accuracy and stability of the OP07, even at high gain, combined
with the freedom from external nulling have made the OP07 an industry standard for instrumentation applications.
The OP07 is available in two standard performance grades. The The OP07 has very low input offset voltage (75 μV maximum for OP07E is specified for operation over the 0°C to 70°C range, OP07E) that is obtained by trimming at the wafer stage. These and the OP07C is specified over the −40°C to +85°C low offset voltages general y eliminate any need for external temperature range. nul ing. The OP07 also features low input bias current (±4 nA for the OP07E) and high open-loop gain (200 V/mV for the OP07E). The OP07 is available in epoxy 8-lead PDIP and 8-lead narrow The low offset and high open-loop gain make the OP07 SOIC packages. For CERDIP and TO-99 packages and standard particularly useful for high gain instrumentation applications. microcircuit drawing (SMD) versions, see the OP77.
