I appreciate the detailed request, but I need to clarify an important issue:

The part number you've requested (OPA4376AIPWR) does not match the datasheet content provided.

The datasheet section you've supplied covers:

• OPA376 (single op-amp, 5-pin and 8-pin packages)
• OPA2376 (dual op-amp, 8-pin SOIC/VSSOP)

The part number OPA4376AIPWR indicates a quad op-amp (the "4" prefix), which is not documented in the provided datasheet excerpt.

What I can do:

1. If you meant OPA2376AIPWR (dual op-amp, 8-pin TSSOP): I can extract that pinout from the OPA2376 diagram shown.
2. If you need OPA4376AIPWR (quad op-amp): You must provide a datasheet section that covers the OPA4376 family, which would have 14 pins in TSSOP package.

Please clarify:

• Did you intend to request OPA2376AIPWR (8-pin)?
• Or do you have a datasheet section for OPA4376 that should be included?

Once confirmed, I'll extract the exact pinout table for the correct part number.

At TA = 25°C, RL = 10 k Ω connected to VS / 2, VCM = VS / 2, and VOUT = VS / 2, unless otherwise noted.

The OPA376 family of operational amplifiers is built using e-trim , a proprietary technique in which offset voltage is adjusted during the final steps of manufacturing. This technique compensates for performance shifts that can occur during the molding process. Through e-trim , the OPA376 family delivers excellent offset voltage (5 μ V, typical). Additionally, the amplifier boasts a fast slew rate, low drift, low noise, and excellent PSRR and AOL. These 5.5-MHz CMOS op amps operate on 760μ A (typical) quiescent current.
