CA3140AMZ

RENESAS · Pre-ordered Chips · SOIC-8

CA3140AMZ from RENESAS, 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 OFFSET NULL passive Offset null terminal for input offset voltage nulling.
2 INV. INPUT input Inverting input of the PMOS-input stage with very high input impedance.
3 NON-INV. INPUT input Non-inverting input of the PMOS-input stage, common-mode range extends down to 0.5V below the negative supply.
4 V- power_in Negative supply terminal (ground in single-supply use); total supply range is 4V to 36V.
5 OFFSET NULL passive Second offset null terminal for input offset voltage nulling.
6 OUTPUT output Bipolar output stage with built-in protection against short circuit to either supply rail or ground.
7 V+ power_in Positive supply terminal; total supply range is 4V to 36V.
8 STROBE input Access terminal for a supplementary external capacitor for additional frequency roll-off.
