Operational amplifier Texas Instruments OPA177GP — single channel, DIP package, 10.2×6.6×4.57 mm

Texas Instruments OPA177GP is a single-channel operational amplifier provided in a through-hole DIP-style package with physical dimensions of approximately 10.2 × 6.6 × 4.57 mm. The device is designed for precision analog signal conditioning and general-purpose amplification in electronic circuits. It is supplied in multi-piece packaging and commonly used in instrument-grade applications that require low offset and stable performance over temperature.

Advantages

The OPA177GP features very low input offset and low drift, achieved through laser-trimmed internal adjustments that reduce the need for external calibration. Low quiescent current reduces warm-up drift and minimizes errors from thermoelectric effects in input connections. The amplifier’s low noise and stable behavior make it suitable for precision measurement and signal-conditioning tasks where accuracy and long-term stability are important.

Suitable for

• Precision instrumentation and data acquisition front ends
• Low-noise signal conditioning and filtering
• General-purpose linear amplification in analog circuits
• Applications requiring low offset and low drift over temperature

Key specifications

• Channels: single-channel operational amplifier
• Package type: through-hole DIP-style package (8-pin form factor)
• Typical quiescent current: low idle current minimizing thermal drift
• Low input offset voltage and low offset drift suitable for precision use
• Low noise performance for accurate analog signal processing
• Typical physical dimensions: 10.2 mm × 6.6 mm × 4.57 mm

How to use

Integrate the OPA177GP into your PCB design using the standard 8-pin DIP footprint and follow recommended analog layout practices: provide clean power decoupling close to the device, maintain short signal traces to reduce noise pickup, and avoid thermal gradients across the amplifier package. Configure the amplifier in the desired topology (inverting, noninverting, filter, integrator, etc.) according to circuit requirements and standard design equations for gain and bandwidth.

Recommendations

For best results, use low-noise resistors and proper bypass capacitors on supply pins. Allow the device to stabilize after power-up to minimize warm-up drift. When replacing older precision op amps in existing designs, verify stability with your chosen feedback network and load conditions.
