LT1999CS8-10#PBF

Analog Devices · Operational Amplifier · SOIC-8

LT1999CS8-10#PBF from Analog Devices, 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 V+ power_in Power supply voltage, tied internally to pin 4, specified for 4.5V to 5.5V operation (not tested below 4.5V).
2 +IN input Positive sense input pin, with common mode range of -5V to 80V.
3 -IN input Negative sense input pin, with common mode range of -5V to 80V.
4 V+ power_in Power supply voltage, tied internally to pin 1, specified for 4.5V to 5.5V operation (not tested below 4.5V).
5 GND power_in Ground pin.
6 REF input Reference pin input that sets the output common mode level, defaulting to mid-supply via two 160k resistors and overdrivable by an external source able to drive 80k.
7 OUT output Voltage output, VOUT = AV*(VSENSE ± VOSI), drives up to 200pF directly; use at least 100 ohm series resistor for larger capacitive loads.
8 SHDN input Shutdown pin that places the part in low power shutdown when pulled within 0.5V of GND, with an internal 2µA pull-up selecting active state when floating.
