| Description | The AD549LHZ is a precision ultralow input bias current operational amplifier manufactured by Analog Devices, designed for applications requiring extremely low input current, high input impedance, and stable DC accuracy. This device is built as a monolithic electrometer operational amplifier and is especially suitable for use with high-impedance signal sources such as photodiodes, photomultiplier tubes, ion chambers, oxygen sensors, and precision current-output transducers. The AD549LHZ features a very low input bias current, typically in the femtoampere to picoampere range, helping minimize measurement error in sensitive analog front-end circuits. It also offers a 1 MHz gain bandwidth product and approximately 3 V/µs slew rate, providing reliable performance in precision signal conditioning applications. The amplifier operates from dual supplies, commonly used around ±15V, with a supported supply range up to approximately ±18V. Its low supply current, typically around 600 µA, helps reduce self-heating effects and supports stable low-current measurements. Packaged in a hermetic TO-99-8 metal can through-hole package, the AD549LHZ provides strong environmental protection and excellent leakage performance for demanding precision analog designs. The AD549LHZ is widely used in electrometer circuits, photodiode preamplifiers, precision integrators, sample-and-hold circuits, medical instrumentation, laboratory measurement systems, and industrial sensor interfaces. |
