Working Principle of OPA2336U/2K5

The OPA2336U/2K5 is a differential input and single-ended output amplifier. It is designed to operate from a single supply voltage, and provides single-supply operation from 1.35V to V CC + 0.35V, or dual-supply operation between GND and V CC + 1V. The amplifier has built-in power-down protection, so it can be safely disabled without the need for external circuitry. Additionally, the device has been optimized to provide excellent temperature stability, high common-mode rejection, low distortion and low power consumption.

The device operates in two main modes:

• Voltage-to-Current Conversion Mode: This mode is used to convert an input voltage (V IN ) to an output current (I OUT ). The input voltage is amplified by the gain of the amplifier, and then converted to an output current with the help of an internal transconductance amplifier. The output current is then converted back to a voltage (V OUT ) by the output stage of the device.
• Voltage-to-Voltage Conversion Mode: The device can also be used as a voltage-to-voltage converter. In this mode, the amplifier is used to convert the input voltage (V IN ) to an output voltage (V OUT ). The gain of the amplifier is adjusted via external feedback components, and the common-mode voltage of the device can also be adjusted with an external compensation capacitor.

The OPA2336U/2K5 is a comprehensive solution for a wide range of applications, thanks to its high performance, low noise, low power consumption, wide input common-mode range, improved output voltage swing and excellent temperature stability.
