RENESAS · Operational Amplifier · DIP-8

CA3140EZ from RENESAS, in a DIP-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, used with pin 5 for input offset voltage nulling.
2 INV. INPUT input Inverting input of the PMOS input stage, whose common-mode input voltage can swing 0.5V below the negative supply terminal.
3 NON-INV. INPUT input Non-inverting input of the PMOS input stage, whose common-mode input voltage can swing 0.5V below the negative supply terminal.
4 V- power_in Negative supply terminal; the device operates from 4V to 36V supply (single or dual supply).
5 OFFSET NULL passive Offset null terminal, used with pin 1 for input offset voltage nulling.
6 OUTPUT output Output of the bipolar output stage, which has built-in protection against damage from a short circuit to either supply rail or to ground.
7 V+ power_in Positive supply terminal; the device operates from 4V to 36V supply (single or dual supply).
8 STROBE input Strobe terminal shown in the pinout; its function is not described in the provided pages.
