概要

Description

The AD8226ARZ is a low-cost, precision instrumentation amplifier from Analog Devices. It is designed for applications requiring high accuracy and stability under varying environmental conditions. This amplifier offers a wide power supply range, from ±2.3 V to ±18 V, and features low noise, low offset voltage, and low offset drift, making it ideal for precision data acquisition systems.
One of its key features is an adjustable gain capability, typically set via external resistors, allowing flexibility in amplifying small differential signals in the presence of high common-mode voltages. It also boasts a high common-mode rejection ratio (CMRR), essential for maintaining accuracy by rejecting unwanted interference or noise present on both input lines.
The AD8226ARZ is housed in a compact SOIC-8 package, making it suitable for space-constrained applications. Its robust design and performance specifications make it suitable for use in medical devices, industrial process controls, and precision sensor interfaces. With its balance of performance, cost, and ease of use, the AD8226ARZ is an excellent choice for engineers needing a reliable instrumentation amplifier solution.

Pinout

The AD8226ARZ is an instrumentation amplifier produced by Analog Devices. It comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here is a concise overview of its pin count and functions:
1. Pin 1 (REF): Reference Voltage Input. This pin allows the user to shift the output voltage. Typically, it is connected to ground.

2. Pin 2 (V- or Negative Supply): Negative Power Supply. This pin provides the negative power supply voltage to the amplifier.
3. Pin 3 (RG): Gain Setting. Gain is set by connecting a resistor between this pin and Pin 4 (also RG).
4. Pin 4 (RG): Gain Setting. Works in conjunction with Pin 3 to set the gain.
5. Pin 5 (VOUT): Output Voltage. This is the output pin where the amplified signal is available.
6. Pin 6 (V+ or Positive Supply): Positive Power Supply. This pin provides the positive power supply voltage to the amplifier.
7. Pin 7 (IN- or Inverting Input): Inverting Input. This is the input pin for the negative side of the differential input signal.
8. Pin 8 (IN+ or Non-Inverting Input): Non-Inverting Input. This is the input pin for the positive side of the differential input signal.
The AD8226 is used in applications requiring precise low-level signal amplification, offering excellent DC performance and high CMRR (Common-Mode Rejection Ratio).
