INA2126UA from Texas Instruments, in a SOIC-16. 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 | V-INA | power_in | Negative input of amplifier A. |
| 2 | V+INA | power_in | Positive input of amplifier A. |
| 3 | RGA | passive | Gain-set pin for amplifier A; for gains greater than 5, a gain resistor is placed between pins 3 and 4 (gain = 5 + 80kΩ/RG). |
| 4 | RGA | passive | Gain-set pin for amplifier A; for gains greater than 5, a gain resistor is placed between pins 3 and 4 (gain = 5 + 80kΩ/RG). |
| 5 | RefA | input | Reference input for amplifier A, which must be driven from a low impedance source or grounded. |
| 6 | VOA | output | Output of amplifier A. |
| 7 | SenseA | input | Feedback sense input for amplifier A, which must be connected to VOA for proper operation. |
| 8 | V- | power_in | Negative power supply; the datasheet recommends ±1.35 V to ±18 V dual supply or 2.7 V to 36 V single supply. |
| 9 | V+ | power_in | Positive power supply; the datasheet recommends ±1.35 V to ±18 V dual supply or 2.7 V to 36 V single supply. |
| 10 | SenseB | input | Feedback sense input for amplifier B, which must be connected to VOB for proper operation. |
| 11 | VOB | output | Output of amplifier B. |
| 12 | RefB | input | Reference input for amplifier B, which must be driven from a low impedance source or grounded. |
| 13 | RGB | passive | Gain-set pin for amplifier B; for gains greater than 5, a gain resistor is placed between pins 13 and 14 (gain = 5 + 80kΩ/RG). |
| 14 | RGB | passive | Gain-set pin for amplifier B; for gains greater than 5, a gain resistor is placed between pins 13 and 14 (gain = 5 + 80kΩ/RG). |
| 15 | V+INB | power_in | Positive input of amplifier B. |
| 16 | V-INB | power_in | Negative input of amplifier B. |
