AD8672ARMZ-R2 Precision Operational Amplifier 2 Circuit
The AD8672ARMZ-R2 is a dual-channel, precision operational amplifier (op-amp) from Analog Devices, designed for high-performance analog circuits requiring low offset voltage, low noise, and high stability. Featuring a maximum input offset voltage of just 50μV and a near-zero drift of 0.2μV/°C, this device ensures exceptional accuracy in precision instrumentation, data acquisition systems, and medical applications. It operates with a low supply current of 650μA per channel (typical) and supports a wide power supply range of ±2.5V to ±18V, making it versatile for both single-supply (5V to 36V) and dual-supply configurations. The AD8672ARMZ-R2 is housed in a compact 8-lead MSOP package, enabling space-efficient designs while maintaining excellent thermal performance.
The AD8672ARMZ-R2 integrates several advanced features to optimize performance in demanding applications. Its ultra-low input bias current of 1pA (typical) minimizes errors in high-impedance circuits, such as photodiode amplifiers and sensor interfaces. The op-amp offers a unity-gain bandwidth of 10MHz and a slew rate of 5V/μs, ensuring fast response times for pulse and transient signals. Additionally, it features rail-to-rail input and output operation, allowing full-scale signal processing without clipping. The device is specified over the extended industrial temperature range (-40°C to +125°C) and includes ESD protection up to 2kV (HBM), enhancing reliability in harsh environments. Its low power consumption and high CMRR (100dB typical) further make it suitable for battery-powered and noise-sensitive systems.
