LT1999HMS8-50F#WPBF from Analog Devices, in a MSOP-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 | Positive sense input pin. |
| 2 | -IN | input | Negative sense input pin. |
| 3 | NC | unconnected | Pin 3 is not connected internally to the die and should be left unconnected. |
| 4 | V+ | power_in | Power supply voltage; the specified range of operation is 4.5V to 5.5V, and lower supply voltages (down to approximately 4V) are possible but the LT1999 is not tested or characterized below 4.5V. |
| 5 | GND | power_in | Ground pin. |
| 6 | REF | input | Reference pin input sets the output common mode level halfway between V+ and GND using a divider of two 160k resistors; it can be overdriven by an external voltage source capable of driving 80k to a mid-supply potential. |
| 7 | OUT | output | Voltage output, VOUT = AV•(VSENSE ± VOSI); the output amplifier drives up to 200pF capacitive loads directly, and loads exceeding 200pF should be decoupled with an external resistor of at least 100Ω. |
| 8 | SHDN | input | Shutdown pin; when pulled to within 0.5V of GND (Pin 5) it places the LT1999 into low power shutdown, and if left floating an internal 2µA pull-up places the LT1999 in the active (amplifying) state. |
