It is a single-channel device capable of operating as an operational amplifier (opamp), buffer amplifier or instrumentation amplifier. The amplifier has a wide frequency range of 10kHz to 10MHz, a low noise of 0.3nV/√Hz, and a low distortion of 0.001%.

Application field

The amplifier is ideal for a variety of low-noise, high-speed applications including:

• Sensor signal conditioning

• Communications systems

• High-speed data converters

• Filter networks

• Gain control

• Switch control

Working principle

The amplifier is a single amplifier that can be used as an operational amplifier, buffer amplifier or instrumentation amplifier. The device has two differential inputs and an output. The differential inputs are effectively the sum and difference of the two inputs of the amplifier. The output of the amplifier is the difference between these two inputs, amplified by a gain of 1, when the gain can be adjusted internally by the use of an external resistor network. The output level can be set using the two programmable gain resistors R1 and R2.

The amplifier is constructed using a high-speed, low-power inverting amplifier topology. The two inputs are biased to a virtual ground and the output is formed by the inverting amplifier. The inverting amplifier has a bandwidth of 5 MHz and is designed to operate with a gain of 1. The gain can be adjusted using the external resistor network. The device is designed to be highly immune to power supply noise and can operate from a supply voltage of up to 20V.
