The AD626A from Analog Devices Inc. is a monolithic, single-supply difference amplifier ideal for amplifying small differential voltages in the presence of large common-mode signals. This high-performance amplifier is designed to offer precision and ease of use in a wide range of applications, from medical instrumentation to industrial process controls.

Key Features:

• Single-Supply Operation: The AD626A operates from a single 5 V to 36 V supply or dual supplies of ±2.5 V to ±18 V, providing flexibility in various circuit configurations.
• High Common-Mode Rejection Ratio (CMRR): With a CMRR of 120 dB (min) at dc, the AD626A ensures accuracy in environments with high common-mode signals.
• Low Voltage Noise: A low voltage noise density of 9 nV/√Hz at 1 kHz makes the AD626A suitable for applications requiring low noise performance.
• Adjustable Gain: The gain can be set from 1 to 1000 with a single external resistor, providing design flexibility and simplifying adjustments.
• High Input Impedance: The AD626A features a high input impedance of 10 GΩ, making it suitable for buffering high-impedance sources.

Applications:

• Medical Instrumentation
• Battery-Powered Instruments
• Data Acquisition Systems
• Industrial Process Controls
• Strain Gauge Amplifiers

The AD626A is encapsulated in a compact 8-lead SOIC or DIP package, allowing for efficient use of board space. Its robust design ensures reliable performance even in harsh industrial environments.
