# LMP8601MA

**Texas Instruments** · Current Sense Amplifiers · SOIC-8

LMP8601MA 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 of the current-sense amplifier, connected across the sense resistor. |
| 2 | GND | power_in | Power supply ground reference for the device. |
| 3 | A1 | output | Preamplifier output (gain of 10), available for adding filter networks or gain adjustment between A1 and A2. |
| 4 | A2 | input | Input to the output buffer, receiving the signal from the external filter network and/or from A1. |
| 5 | OUT | output | Single-ended amplifier output, with gain of 2, 5 or 10 depending on the variant (LMP8601-Q1, LMP8602-Q1, LMP8603-Q1). |
| 6 | VS | power_in | Positive power supply voltage pin; the recommended operating supply range is 3 V to 5.5 V. |
| 7 | OFFSET | input | DC offset voltage input that level-shifts the output for bidirectional sensing; it must be driven from a very low impedance source (< 10 Ω). |
| 8 | +IN | input | Positive differential input of the current-sense amplifier, connected across the sense resistor. |
