Overview of AD549LHZ by Analog Devices Inc.
The AD549LHZ is an ultralow input-bias current operational amplifier (op-amp) developed by Analog Devices Inc. This device is encapsulated within a TO99-8 package, distinguishing itself by its remarkably low bias current of just 60 picoamperes (typical at 25°C), making it an exceptional choice for applications that require precision and minimal power consumption.
This component falls under the Operational Amplifiers category, a subclass of Amplifier Circuits, and it integrates numerous features that are beneficial for a wide array of applications. These features include a nominal common-mode rejection ratio (CMRR) of 90 dB, voltage-feedback architecture, frequency compensation, and an average bias current-max of 6e-8 µA. Additionally, the AD549LHZ operates with a nominal supply voltage of ±15 V, a maximum supply current of 0.7 mA, and provides a nominal unity-gain bandwidth of 1 kHz with a minimum voltage gain of 80,000.
The device also boasts robust temperature performance, operating up to a maximum of 70°C. Despite its noncompliance with Pb-free standards, it adheres to RoHS regulations, emphasizing Analog Devices’ commitment to environmentally responsible manufacturing practices. The gold (Au) terminal finish further underscores its reliability and quality by offering enhanced conductivity and corrosion resistance.
Industry Applications for AD549LHZ
The inherent characteristics of the AD549LHZ mean it could potentially be utilized across a broad range of industries where measurement accuracy, minimal power drift, and high impedance are critical.
