Additional Details

The KIA324P/P operates from a dual power supply, typically ranging from ±3V to ±16V. The amplifier exhibits a high open-loop gain, a low input bias current, and a low input offset voltage. The output voltage swing is typically limited by the supply voltage rails. The amplifier is available in a DIP-14 or SOIC-14 package. The slew rate, a measure of how quickly the output voltage can change, is typically around 0.5 V/µs. This amplifier is generally suitable for general-purpose applications where high bandwidth is not a primary requirement.
