LHAMP189FAA from Legendsemi, in a SOP-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 | IN- | input | Negative input of the instrumentation amplifier; input range is (V-) + 0.1 V to (V+) - 1.5 V and it is diode-clamped to the supply rails (limit to 10 mA if beyond rails). |
| 2 | RG | passive | Gain setting pin; for gains greater than 1 place a gain resistor between the two RG pins, G = 1 + (49.4 kΩ / RG). |
| 3 | RG | passive | Gain setting pin; for gains greater than 1 place a gain resistor between the two RG pins, G = 1 + (49.4 kΩ / RG). |
| 4 | IN+ | input | Positive input of the instrumentation amplifier; input range is (V-) + 0.1 V to (V+) - 1.5 V and it is diode-clamped to the supply rails (limit to 10 mA if beyond rails). |
| 5 | V- | power_in | Negative supply; total supply range is 4 V to 36 V single or ±2 V to ±18 V dual. |
| 6 | REF | input | Reference input that must be driven by low impedance or connected to ground, with input impedance of 40 kΩ and a voltage range from V- to V+. |
| 7 | OUT | output | Rail-to-rail output with short-circuit current of ±32 mA and capacitive load drive of 0.1 nF. |
| 8 | V+ | power_in | Positive supply; total supply range is 4 V to 36 V single or ±2 V to ±18 V dual, with 40 V single-supply absolute maximum. |
