GENERAL DESCRIPTION The OP07D is a precision, ultralow offset amplifier. Printable Data Sheet Subscribe. transistor amplifier circuit. The OP07 also features low input bias current ( 4 nA for the OP07E) and high open-loop gain (200 V/mV for th e OP07E). The OP07 has very low input offset voltage (75 V maximum for OP07E) that is obtained by trimming at the wafer stage. The maximum input offset voltage for OP07E is 75V. The range for supply voltage is from 3 V to 18 V. CMRR is high. For OP07E, it is of 106 dB. It has high input impedance and provides a low-noise operation. Where to use it? The OP07E is specified for operation over the 0 C to 70 C range, and OP07C over the 40 C to +85 C temperature range. Comparators.
