CA3140AMZ96

@@ -8,14 +8,14 @@ CA3140AMZ96 from RENESAS, in a SOIC-8. Pinout and pin descriptions extracted fro  | Pin | Name | Type | Function | |---|---|---|---|-| 1 | OFFSET_NULL | passive | Offset-null terminal. Connect a 10kΩ potentiometer between pins 1 and 5 with the wiper returned to pin 4 (V-) to trim the input offset voltage to zero. May also be used with pin 8 for supplementary Miller-effect compensation (extra roll-off). |-| 2 | INV_INPUT | input | Inverting input (−) of the op-amp. High-impedance PMOS-FET gate, ZIN≈1.5TΩ, input current ≈10pA at ±15V. Do not exceed ±8V differential input voltage; use a series limiting resistor if input can be driven below V-. |-| 3 | NON_INV_INPUT | input | Non-inverting input (+) of the op-amp. High-impedance PMOS-FET gate; common-mode input range extends from about 0.5V below V- up to (V+ − 2V). Same absolute-max input-current limit of 1mA applies. |-| 4 | V- | power_in | Negative supply rail (or ground in single-supply operation). Total supply V+ to V- may range from 4V to 36V absolute maximum. Also serves as the reference return for offset-null and strobe circuits. |-| 5 | OFFSET_NULL | passive | Second offset-null terminal. Paired with pin 1 via a 10kΩ trim-pot whose wiper returns to pin 4 (V-) to null the input offset voltage. |-| 6 | OUTPUT | output | Op-amp output. Class-AB bipolar stage; VOM+ typ +13V, VOM- typ −14.4V at RL=2kΩ and ±15V supply. Short-circuit protected to either supply rail; source ≈40mA, sink ≈18mA. |-| 7 | V+ | power_in | Positive supply rail. Operates from 4V (single supply) to ±18V (dual supply); absolute-max V+ to V- is 36V. Typical total supply current I+ ≈ 4mA. |-| 8 | STROBE | input | Strobe / output-disable terminal. When tied to V- (pin 4) by mechanical or electrical means, the output at pin 6 swings low to approximately V- potential (sinks ~220µA from pin 8 to pin 4). Can also be used with pin 1 for external Miller-effect roll-off compensation. |+| 1 | OFFSET_NULL | passive | Offset-null adjust terminal. Connect a potentiometer (typ ~18kΩ for CA3140A) between pins 1 and 5 with the wiper to V- (pin 4) to trim the input offset voltage to zero. |+| 2 | INV_INPUT | input | Inverting input (-) of the op-amp. High-impedance PMOS gate; input impedance ~1.5TΩ, input current ~10pA (typ, ±15V supply). Absolute input voltage limited to (V+ +8V) to (V- -0.5V). |+| 3 | NON-INV_INPUT | input | Non-inverting input (+) of the op-amp. High-impedance PMOS gate; common-mode range extends from ~V- -0.5V up to ~V+ -1.5V at ±15V (typ -15.5V to +12.5V). |+| 4 | V- | power_in | Negative supply rail (or ground in single-supply operation). Total supply voltage V+ to V- must not exceed 36V. Serves as the reference to which the output can swing to within ~0.13V in single-supply use. |+| 5 | OFFSET_NULL | passive | Second offset-null adjust terminal. Used with pin 1 and a potentiometer whose wiper returns to V- (pin 4) to trim V_IO. May alternatively be used with pin 4 for offset adjustment. |+| 6 | OUTPUT | output | Bipolar op-amp output. Short-circuit protected to either supply rail. Typical output swing +13V/-14.4V at ±15V into 2kΩ; source/sink short-circuit currents ~40mA/18mA. |+| 7 | V+ | power_in | Positive supply rail. Operating supply range 4V to 36V (single or dual). Typical supply current 4mA at ±15V (6mA max). |+| 8 | STROBE | input | Strobe/output-disable terminal. Sinking ~220µA from pin 8 to pin 4 (V-) forces the output to swing low, allowing the amplifier to be gated off. Also provides an access point for adding an external compensation capacitor if additional frequency roll-off is desired. |  ## Key specifications
