# OPA241PA

**Texas Instruments** · Operational Amplifier · PDIP-8

OPA241PA from Texas Instruments, in a PDIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | TRIM | passive | External offset voltage adjustment pin for the single-channel OPA241; the datasheet refers to Section 6.1.2 for trim use, which is not included in this excerpt. |
| 2 | -IN | input | Inverting input of the amplifier. |
| 3 | +IN | input | Noninverting input of the amplifier; the input common-mode range extends to 200mV below the negative supply rail. |
| 4 | V- | power_in | Negative (lowest) power supply; recommended VS is 2.7V to 36V single supply or ±1.35V to ±18V dual supply. |
| 5 | TRIM | passive | External offset voltage adjustment pin, paired with pin 1 for the single-channel OPA241; see Section 6.1.2 of the datasheet for trim use. |
| 6 | OUT | output | Amplifier output, which swings rail-to-rail to within 50mV of the supply rails. |
| 7 | V+ | power_in | Positive (highest) power supply; recommended VS is 2.7V to 36V single supply or ±1.35V to ±18V dual supply. |
| 8 | NC | unconnected | No internal connection; can be left floating. |
