CA3240EZ

RENESAS · Operational Amplifier · PDIP-8

CA3240EZ 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 OUTPUT (A) output Output of amplifier A; the datasheet cites Terminal 1 as an output in the touch-switch application, and the output may be shorted indefinitely to ground or either supply within the power dissipation limits (Note 1).
2 INV. INPUT (A) input Inverting input of amplifier A; the differential input voltage is limited to 8V and the input current to 1mA maximum, so a series current-limiting resistor is recommended.
3 NON-INV. INPUT (A) input Non-inverting input of amplifier A; the common-mode input range extends to 0.5V below the negative supply rail, and input current is typically 10pA at 15V.
4 V- power_in Negative supply rail; the operating supply range is 4V to 36V or 2V to 18V total (V+ to V-), and the absolute maximum supply voltage is 36V.
5 INPUT (B) input Non-inverting input of amplifier B; the common-mode input range extends to 0.5V below the negative supply rail, and input current is typically 10pA at 15V.
6 INPUT (B) input Inverting input of amplifier B; the differential input voltage is limited to 8V and the input current to 1mA maximum, so a series current-limiting resistor is recommended.
7 OUTPUT (B) output Output of amplifier B; the datasheet cites Terminal 7 as the output in the touch-switch application, and the output may be shorted indefinitely to ground or either supply within the power dissipation limits (Note 1).
8 V+ power_in Positive supply rail; the operating supply range is 4V to 36V or 2V to 18V total (V+ to V-), and the absolute maximum supply voltage is 36V.
