LMP8603MAX

Texas Instruments · Current Sense Amplifiers · SOIC-8

LMP8603MAX 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	-IN	input	Negative differential input, with a common-mode range of -22 V to 60 V at VS = 5 V (-4 V to 27 V at VS = 3.3 V) and an absolute maximum common-mode voltage of -25 V to 65 V.
2	GND	power_in	Power ground reference; the supply voltage (VS - GND) is rated -0.3 V to 6 V absolute maximum.
3	A1	output	Preamplifier output (gain of 10) taken through the internal 100 kΩ resistor, where an external gain-adjust or filter network can be placed between A1 and A2.
4	A2	input	Input to the output buffer, accepting signals from an external filter network and/or A1, with a typical input bias current of ±2 pA.
5	OUT	output	Single-ended output with an output buffer gain of 10 for the LMP8603-Q1 (2 for LMP8601-Q1, 5 for LMP8602-Q1), referenced to GND when OFFSET is grounded.
6	VS	power_in	Positive supply pin with a recommended operating range of 3 V to 5.5 V; a 0.1 µF bypass capacitor should be placed as close to this pin as possible, referenced to GND.
7	OFFSET	input	DC offset input that sets bidirectional operation when tied to VS and unidirectional (GND-referenced) operation when tied to GND, and must be driven from a source below 10 Ω; the offset voltage range is 0 to VS.
8	+IN	input	Positive differential input, with a common-mode range of -22 V to 60 V at VS = 5 V (-4 V to 27 V at VS = 3.3 V) and an absolute maximum common-mode voltage of -25 V to 65 V.
