LT1635CS8#PBF

Analog Devices · Operational Amplifier · SO-8

LT1635CS8#PBF from Analog Devices, in a SO-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 REFOUT output Reference amplifier output providing the 200mV reference (referred to V-) when pin 1 is tied to REF FB pin 8; it can source 2mA and sink 10µA and swings only to within 0.8V (typ) of the positive rail.
2 OP AMP IN (-) input Inverting input of the rail-to-rail output op amp, with phase reversal protection and protective input resistors.
3 OP AMP IN (+) input Noninverting input of the op amp, whose common mode range includes ground (0V to 4V at VS = 5V).
4 V- power_in Negative supply (ground in single-supply operation); the 200mV reference is referenced to this pin.
5 BALANCE passive Offset null pin, connected to a variable voltage derived from the reference output to adjust the op amp offset by typically -2mV to 8mV.
6 OP AMP OUT output Rail-to-rail op amp output that swings within 15mV of each rail with no load, delivers 20mA min, and drives up to 1000pF.
7 V+ power_in Positive supply pin (1.2V to ±5V total up to 14V max), to be bypassed with about 0.1µF.
8 REF FB input Reference amplifier feedback input, tied to pin 1 for a 200mV (189mV to 211mV) sense voltage, with feedback current of 3.5nA typ into the pin.
