ADA4940-2ACPZ-RL

The ADA4940-2ACPZ-RL is a buffered, low-noise, wideband analog instrumentation amplifier with a gain of up to 500 V/V. This IC chip is based on the Operational Transconductance Amplifier (OTA) design which enables the use of high speed transistors to achieve a wide bandwidth. It is normally used in an instrumentation amplifier as an additional gain block. The operation of the device is dependent on the control voltage (VC) of the circuit. When an input signal is applied to the input terminals, this signal is amplified and the output voltage (Vout) is proportional to the control voltage supplied. The device also has a gain ripple reduction function to reduce the gain variation at different frequencies. The integrated circuit also offers fast switching time, low output noise, low input offset voltage, and low quiescent power consumption.

Along with its high gain, the ADA4940-2ACPZ-RL offers very high accuracy, making it ideal for use in signal processing and data acquisition applications. The device also features a rail-to-rail output stage, making it suitable for use in single-supply systems. Its high safety factor, low distortion, and low noise make it suitable for high-demanding applications such as medical instruments, power supplies, and line transmitted signal processing.
