INA2126U 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 | Inverting input of amplifier A; input voltage is clamped by internal diodes to the supply rails, and source current should be limited to 10 mA if the signal exceeds the supplies. |
| 2 | V+INA | power_in | Non-inverting input of amplifier A; input voltage is clamped by internal diodes to the supply rails, and source current should be limited to 10 mA if the signal exceeds the supplies. |
| 3 | RGA | passive | Gain-set pin for amplifier A; for gains greater than 5, a gain resistor RG is placed between pins 3 and 4 (G = 5 + 80 kΩ / RG). |
| 4 | RGA | passive | Gain-set pin for amplifier A; for gains greater than 5, a gain resistor RG is placed between pins 3 and 4 (G = 5 + 80 kΩ / RG). |
| 5 | RefA | input | Reference input for amplifier A; this pin must be driven from a low-impedance source or tied to ground. |
| 6 | VOA | output | Output of amplifier A; connect to SenseA (pin 7) for proper operation. |
| 7 | SenseA | input | Feedback sense input for amplifier A; must be connected to output VOA (pin 6) for proper operation. |
| 8 | V- | power_in | Negative power supply; dual supply range is ±1.35 V to ±18 V, or single supply 2.7 V to 36 V (V- to V+). |
| 9 | V+ | power_in | Positive power supply; dual supply range is ±1.35 V to ±18 V, or single supply 2.7 V to 36 V (V- to V+). |
| 10 | SenseB | input | Feedback sense input for amplifier B; must be connected to output VOB (pin 11) for proper operation. |
| 11 | VOB | output | Output of amplifier B; connect to SenseB (pin 10) for proper operation. |
| 12 | RefB | input | Reference input for amplifier B; this pin must be driven from a low-impedance source or tied to ground. |
| 13 | RGB | passive | Gain-set pin for amplifier B; for gains greater than 5, a gain resistor RG is placed between pins 13 and 14 (G = 5 + 80 kΩ / RG). |
| 14 | RGB | passive | Gain-set pin for amplifier B; for gains greater than 5, a gain resistor RG is placed between pins 13 and 14 (G = 5 + 80 kΩ / RG). |
| 15 | V+INB | power_in | Non-inverting input of amplifier B; input voltage is clamped by internal diodes to the supply rails, and source current should be limited to 10 mA if the signal exceeds the supplies. |
| 16 | V-INB | power_in | Inverting input of amplifier B; input voltage is clamped by internal diodes to the supply rails, and source current should be limited to 10 mA if the signal exceeds the supplies. |
