The AD628ARMZ-R7 is a precision, low power instrumentation amplifier with a 1.8V to 5.5V supply voltage range, low power consumption, and low 1/f noise. It is ideal for portable and battery-powered applications.

The device features a basic gain range of 1 to 100, an input common-mode range extending below the negative rail, an output level offset pin, a settling time of 125µs, and a wide operating temperature range of -40°C to +125°C. Its temperature range and stability are ideal for closed-loop applications. The device offers good output noise performance and can operate over wide temperature ranges.

Working Principle

The AD628ARMZ-R7 is a precision, low power instrumentation amplifier that uses a single-ended, 3-opamp design to amplify differential input signals. It is designed to operate from a single power supply voltage of 1.8V to 5.5V. The device has a basic gain range of 1 to 100 and an input common-mode range that extends below the negative power supply rail. It features a settling time of 125µs and a quiescent current of 500µA.

The device has an output buffer amplifier with an enable pin to reduce static and dynamic power consumption. The output buffer is capable of driving both digital-to-analog and analog-to-digital converters as well as digital logic. A 2.2nF capacitor connected between the output level offset pin and ground sets the DC offset voltage for the output buffer amplifier. The output level offset pin is designed to minimize the DC offset voltage and output voltage noise, reducing the distortion and crosstalk between channels.

Application Field

The AD628ARMZ-R7 is ideal for low-power, precision instrumentation applications, including professional audio equipment, instrumentation systems, and monitoring/control systems. It is also suitable for medical and industrial applications, where a low supply voltage, low power, and high precision are desirable. Examples include accelerometers and gyroscopes, oxygen sensors, strain gages, and pressure transducers.

The device is also suitable for automotive applications where a low supply voltage, low power, and high precision are desirable, such as automated parking systems, real-time engine management systems, and car navigation systems. Its low power consumption and wide temperature range make it suitable for battery-powered applications and remote sensing systems.
