INA2141UA from Texas Instruments, in a SOIC-16-300mil. 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 | VINA- | input | Inverting input of channel A, protected to ±40V. |
| 2 | VINA+ | input | Noninverting input of channel A, protected to ±40V. |
| 3 | JA | passive | Channel A gain-set jumper pin; G = 10V/V with no jumper to pin 4 and G = 100V/V with a low-resistance jumper installed. |
| 4 | JA | passive | Channel A gain-set jumper pin; connect to pin 3 with a low-resistance jumper for G = 100V/V (0.5Ω in series lowers gain by 0.1%). |
| 5 | RefA | input | Channel A output reference terminal, normally grounded and requiring a low-impedance connection to preserve CMR. |
| 6 | VOA | output | Channel A output, referred to RefA; drives loads of 10kΩ with stable load capacitance up to 1000pF. |
| 7 | SenseA | input | Channel A output sense feedback connection, which must be connected to the VOA output (or load) for proper operation. |
| 8 | V- | power_in | Negative supply voltage, operating range from -2.25V to -18V. |
| 9 | V+ | power_in | Positive supply voltage, operating range from +2.25V to +18V. |
| 10 | SenseB | input | Channel B output sense feedback connection, which must be connected to the VOB output (or load) for proper operation. |
| 11 | VOB | output | Channel B output, referred to RefB; drives loads of 10kΩ with stable load capacitance up to 1000pF. |
| 12 | RefB | input | Channel B output reference terminal, normally grounded and requiring a low-impedance connection to preserve CMR. |
| 13 | JB | passive | Channel B gain-set jumper pin; connect to pin 14 with a low-resistance jumper for G = 100V/V (0.5Ω in series lowers gain by 0.1%). |
| 14 | JB | passive | Channel B gain-set jumper pin; G = 10V/V with no jumper to pin 13 and G = 100V/V with a low-resistance jumper installed. |
| 15 | VINB+ | input | Noninverting input of channel B, protected to ±40V. |
| 16 | VINB- | input | Inverting input of channel B, protected to ±40V. |
