LT1638CMS8#TRPBF

Analog Devices · Precision OpAmps · MSOP-8

LT1638CMS8#TRPBF 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 OUT A output Output of amplifier A, which swings within 20mV of the positive rail and within 3mV of the negative rail with no load and sources or sinks over 40mA on ±15V supplies.
2 -IN A input Inverting input of amplifier A, which is protected by an internal 1kΩ series resistor and a diode to V- for excursions up to 2V below V-, and can be taken up to 44V above V- regardless of V+.
3 +IN A input Non-inverting input of amplifier A, whose common-mode range includes both supplies and which can operate with its input above V+, with inputs rated to 44V differential and common mode.
4 V- power_in Negative supply pin; the device operates from a total supply of 2.5V to 44V on single or split supplies and is reverse battery protected to 18V.
5 +IN B input Non-inverting input of amplifier B, whose common-mode range includes both supplies and which can operate with its input above V+, with inputs rated to 44V differential and common mode.
6 -IN B input Inverting input of amplifier B, which is protected by an internal 1kΩ series resistor and a diode to V- for excursions up to 2V below V-, and can be taken up to 44V above V- regardless of V+.
7 OUT B output Output of amplifier B, which swings within 20mV of the positive rail and within 3mV of the negative rail with no load and sources or sinks over 40mA on ±15V supplies.
8 V+ power_in Positive supply pin; the positive supply should be bypassed with a small capacitor (typically 0.1µF) within an inch of the pin, and the device is rated for a total supply of 2.5V to 44V.
