GM45002ARZ-R7

GONGMOSEMI · Precision Op Amps · SOIC-8-EP

GM45002ARZ-R7 from GONGMOSEMI, in a SOIC-8-EP. 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	OUTA	output	Output of amplifier A; the datasheet gives the output current as ±220 mA at VS=±2.5 V and ±50 mA at VS=2.7 V (VOUT=±0.5 V).
2	-INA	input	Inverting input of amplifier A; the input voltage should not exceed the supply by more than 0.3 V, and the input current should be limited to less than 5 mA with a series resistor if a higher input voltage is applied.
3	+INA	input	Non-inverting input of amplifier A; the input common-mode range is 0 V to 5 V, and the input should not exceed the supply by more than 0.3 V (input current limited to less than 5 mA).
4	V-	power_in	Negative power supply terminal; the device operates from a 2.7 V to 5.5 V single supply or ±1.35 V to ±2.75 V split supply, with an absolute maximum V+ to V- of 6 V.
5	+INB	input	Non-inverting input of amplifier B; the input common-mode range is 0 V to 5 V, and the input should not exceed the supply by more than 0.3 V (input current limited to less than 5 mA).
6	-INB	input	Inverting input of amplifier B; the input voltage should not exceed the supply by more than 0.3 V, and the input current should be limited to less than 5 mA with a series resistor if a higher input voltage is applied.
7	OUTB	output	Output of amplifier B; the datasheet gives the output current as ±220 mA at VS=±2.5 V and ±50 mA at VS=2.7 V (VOUT=±0.5 V).
8	V+	power_in	Positive power supply terminal; the device operates from 2.7 V to 5.5 V, with an absolute maximum V+ to V- of 6 V.
9	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
