Precision DC amplifier for 8-DIP through-hole boards
The OP-07DP is a single-channel general-purpose precision operational amplifier in the legacy 8-DIP through-hole package. It is designed for applications where DC accuracy matters more than bandwidth — bridge amplifiers, thermocouple conditioners, strain-gauge front-ends, and precision integrators that operate well below the 600 kHz gain-bandwidth ceiling.
600 kHz GBP and 0.3 V/µs slew rate — the bandwidth budget
The 600 kHz gain-bandwidth product sets the small-signal bandwidth: at a closed-loop gain of 100 (40 dB), the -3 dB point sits at 6 kHz. The 0.3 V/µs slew rate is the large-signal limit — for a 10 V output swing, the full-power bandwidth is roughly 4.8 kHz. This part is not intended for audio line drivers or fast ADC buffers; it belongs in DC measurement and low-frequency analog processing where the trade-off for precision is acceptable.
150 µV Vio and 12 nA Ib — the input stage that defines precision
Maximum input offset voltage of 150 µV and typical input bias current of 12 nA place the OP-07DP in the precision class for a general-purpose op-amp. In a thermocouple amplifier with a gain of 1000, the input offset translates to 150 mV at the output — trimmable with a nulling potentiometer if the circuit requires it. The bias current of 12 nA into a 10 kΩ source resistor produces 120 µV of additional offset error, well below the Vio itself.
6 V to 36 V supply span — single or dual rails
The supply span from 6 V to 36 V allows operation from a single 9 V battery or from ±3 V to ±18 V dual supplies. The commercial temperature range of 0°C to 70°C limits the part to indoor, conditioned environments — not suitable for engine bays, outdoor enclosures, or industrial ovens without temperature control.
Active production — no obsolescence risk for new designs
The OP-07DP carries an active lifecycle status from the manufacturer. It is RoHS3 compliant, meaning the terminations are lead-free and the part meets current EU substance restrictions. For a precision op-amp in a through-hole package still specified into new BOMs, this is the straightforward sourcing case: quoted to order against the line-item quantity.
