impedance provide high accuracy in the noninverting circuit
configuration. Excellent linearity and gain accuracy can be
maintained even at high closed-loop gains. Stability of offsets
and gain with time or variations in temperature is excellent. The
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.
GENERAL DESCRIPTION
The OP07 is available in two standard performance grades. The
OP07E is specified for operation over the 0°C to 70°C range,
and the OP07C is specified over the −40°C to +85°C
temperature range.
The OP07 has very low input offset voltage (75 μV maximum for
OP07E) that is obtained by trimming at the wafer stage. These
low offset voltages generally eliminate any need for external
nulling. 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 low offset and high open-loop gain make the OP07
The OP07 is available in epoxy 8-lead PDIP and 8-lead narrow
SOIC packages. For CERDIP and TO-99 packages and standard
microcircuit drawing (SMD) versions, see the OP77.
