LHAMP189FAA

Legendsemi · Instrumentation Amplifiers · SOP-8

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.
