INA148UA from Texas Instruments, in a SOIC-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 | REF | input | Reference voltage input where VOUT = (+IN) - (-IN) + VREF; requires source impedance ≤ 5Ω to maintain 86dB CMRR. |
| 2 | -IN | input | Inverting differential input rated for ±200V continuous and ±500V peak (0.1s); common-mode input range ±200V (dual supply ±15V), ±100V (dual supply ±5V), or -47.5V to +75V (single supply +5V). |
| 3 | +IN | input | Non-inverting differential input rated for ±200V continuous and ±500V peak (0.1s); common-mode input range ±200V (dual supply ±15V), ±100V (dual supply ±5V), or -4V to +32.5V (single supply +5V). |
| 4 | V- | power_in | Negative power supply rail; rated ±1.35V to ±18V (dual supply) or GND (single supply mode); absolute maximum ±18V dual or 36V single supply. |
| 5 | NC | unconnected | No connection pad; leave unconnected. |
| 6 | OUT | output | Differential amplifier output; voltage swing (V-) + 0.5V to (V+) - 1.5V with RL = 10kΩ load; short-circuit current ±13mA (SHE process) or ±20mA (TID process) continuous. |
| 7 | V+ | power_in | Positive power supply rail; rated ±1.35V to ±18V (dual supply) or 2.7V to 36V (single supply); use low-ESR bypass capacitor connected close to pin. |
| 8 | NC | unconnected | No connection pad; leave unconnected. |
