Application Field

The AD823ANZ is a general-purpose analog amplifier and buffer, offering excellent AC and DC performance for a wide range of applications. The device is particularly suitable for use as a voltage amplifier, transconductance amplifier, current-to-voltage converter, active integrator, and power supply manager. Due to its low input offset voltage and low noise, the AD823ANZ is well suited to applications requiring high precision and low noise operation.

The AD823ANZ is well-suited to applications such as test and measurement, active filters, signal conditioning, audio and video, line drivers, sample and hold systems, sense network monitors and power management. It is also ideal for use in medical and industrial control systems.

Working Principle

The AD823ANZ offers excellent AC and DC performance for a wide range of applications. The device uses a low-noise, wide-bandwidth, high-current amplifier inside an 8-pin TSSOP package. The AD823ANZ includes a nested, cascoded differential pair of transistors and a fully compensated current source to provide significantly reduced levels of distortion and excellent linearity without trimming.

The amplifier is built around a high level of output current drive and a tight output voltage swing. The wide-bandwidth, high-current amplifier and current source provide fast settling of the output voltage. This allows the amplifier to respond quickly to wide-dynamic range input signals, while keeping distortion and noise levels low. The AD823ANZ can handle up to + 6.5V and is capable of outputting up to ± 1A into a 2.5Ω load.

The high output current drive of the device allows it to easily drive active sensing, power management, and analog signal conditioning applications. The device also has integrated protection circuits to prevent the output from being overloaded and ensure safe operation. Additionally, the device is protected from input voltage spikes and can tolerate transient voltages up to 24V.

Conclusion

The AD823ANZ is a linear amplifier, buffer amp, and instrumentation OP amp with improved performance. It is designed for general-purpose analog applications, providing excellent output current drive, low input offset voltage, and low noise. The wide bandwidth, high current amplifier and current source provide fast settling of the output voltage with low distortion and excellent linearity. The AD823ANZ is suitable for use in test and measurement, filtering, active sensing, signal conditioning, and power management, and can handle up to + 6.5V and ± 1A into a 2.5Ω load.
