CA3140AEZ

RENESAS · Operational Amplifier · PDIP-8

CA3140AEZ from RENESAS, in a PDIP-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 provided for input offset voltage nulling, used together with pin 5.
2 INV. INPUT input Inverting input of the PMOS-input operational amplifier, with very low input current (typically 10 pA at 15 V) and common-mode range extending 0.5 V below the negative supply.
3 NON-INV. INPUT input Non-inverting input whose common-mode voltage can be swung 0.5 V below the negative supply terminal.
4 V- power_in Negative supply terminal; the device operates from 4 V to 36 V total supply, single or dual.
5 OFFSET NULL passive Second 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 load short circuit to either supply rail or to ground.
7 V+ power_in Positive supply terminal; the device operates from 4 V to 36 V total supply, single or dual.
8 STROBE input Strobe terminal as labelled in the pinout figure; the provided datasheet text gives no function or limits for it.
