INA114AP from Texas Instruments, in a DIP-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 | RG | passive | Gain-setting resistor terminal; external RG between pins 1 and 8 sets gain G = 1 + 50kΩ/RG (range 1 to 10000). |
| 2 | V-IN | power_in | Inverting input, protected to ±40V, and needs a bias current return path. |
| 3 | V+IN | power_in | Non-inverting input, protected to ±40V, and needs a bias current return path. |
| 4 | V- | power_in | Negative supply; dual supply range is ±2.25V to ±18V. |
| 5 | Ref | input | Output reference pin, normally grounded, and must be low impedance to maintain good common-mode rejection. |
| 6 | VO | output | Amplifier output, short-circuit current +20/-15mA, with the output sense connected internally in the DIP version. |
| 7 | V+ | power_in | Positive supply; dual supply range is ±2.25V to ±18V (single supply 4.5V to 36V). |
| 8 | RG | passive | Gain-setting resistor terminal; external RG between pins 1 and 8 sets gain G = 1 + 50kΩ/RG (range 1 to 10000). |
