AD8138ARMZ

Analog Devices · Differential OpAmps · MSOP-8

AD8138ARMZ 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 Negative input summing node.
2 VOCM input Voltage applied to this pin sets the output common-mode voltage with a ratio of 1:1, e.g. 1 V dc on VOCM sets the dc bias level on +OUT and -OUT to 1 V.
3 V+ power_in Positive supply voltage (supply range +3 V to ±5 V, absolute maximum ±5.5 V).
4 +OUT output Positive output; the voltage at -DIN is inverted at +OUT.
5 -OUT output Negative output; the voltage at +DIN is inverted at -OUT.
6 V- power_in Negative supply voltage.
7 NC unconnected No connect.
8 +IN input Positive input summing node.
