The AD8264ACPZ is an ultra-low noise, low bypass current instrumentation amplifier with a fixed gain of 1, designed for high precision applications. It features low offset voltage, high common-mode rejection ratio (CMRR), and low noise. It is suitable for a wide range of high precision applications such as data acquisition systems, strain gauge amplifiers, medical instrumentation, and various other process measurements.

The AD8264ACPZ is comprised of two matched, low-noise differential amplifiers with a slight gain difference. A precision resistor divider provides gain setting, while the remainder of the circuit is optimized to ensure low noise and low power consumption. The internal compensation pins can be used to adjust offset voltage and common-mode rejection ratio when necessary.

Working Principle:

The AD8264ACPZ operates as an inverting amplifier with an open loop gain of 1. A differential input signal is applied across the two input pins, and the output voltage is determined by the voltage difference between the two input pins. A precision resistor divider provides gain setting, and the internal compensation pins can be used to adjust offset voltage and common-mode rejection ratio if needed.

The AD8264ACPZ is designed for use with a wide range of input signals, from low-level signals to high-level signals with common-mode voltages up to 6V. It also features a fast settling time of 2.4μs for a 10V output step. The AD8264ACPZ can be used as an instrumentation amplifier, differential amplifier, or post-amplifier.

Applications:

The AD8264ACPZ is designed for use in a wide array of high precision applications. Its low noise performance and wide range of input signals make it ideal for use in data acquisition systems, strain gauge amplifiers, medical instrumentation, and various other process measurements. It is also suitable for applications where low noise and high accuracy is required, such as measuremement of pressure, strain, temperature, and flow.

In addition, the AD8264ACPZ is designed for use with a single supply and has a wide common-mode voltage range, making it ideal for use in battery-operated instruments. It can also be used in combination with other precision amplifiers to form a programmable gain instrumentation amplifier.

The AD8264ACPZ is a high performance, low noise, application specific instrumentation amplifier for high precision applications. Its low offset voltage, high common-mode rejection ratio (CMRR), and fast settling time make it perfect for a wide range of applications including data acquisition systems, strain gauge amplifiers, medical instrumentation, and various other process measurements. It is also suitable for applications where low noise and high accuracy is required.
