ADA4805-2ARMZ 105 MHz, Rail-to-Rail Operational Amplifier 2 Circuit
The ADA4805-2ARMZ, manufactured by Analog Devices, is a dual-channel, high-speed voltage feedback operational amplifier featuring rail-to-rail outputs and an exceptionally low quiescent current of 500 µA per amplifier. Housed in a compact 8-lead MSOP surface-mount package, this device is part of the ADA4805-2 series and is recommended for new designs. The amplifier operates over a wide supply voltage range from 2.7 V to 10 V (or ±1.5 V to ±5 V) and is fully specified at VS = 3 V, 5 V, and ±5 V. The device leverages Analog Devices' proprietary XFCB (extra fast complementary bipolar) process, delivering both low voltage and low current noise performance.
The ADA4805-2ARMZ is ideally suited for low-power, high-resolution data conversion systems, serving as an exceptional driver for high-precision analog-to-digital converters (ADCs). In battery-powered instrumentation and portable test equipment, the ultralow 500 µA quiescent current per channel extends operational runtime significantly. The device is widely deployed in medical monitoring devices, automotive sensor interfaces, and data acquisition systems requiring high-speed, low-noise signal conditioning. Additional applications include micro-power active filters, portable point-of-sale terminals, active RFID readers, photomultiplier tubes, and ADC reference buffers. The ADA4805-2ARMZ also finds use in solar power inverters, energy management systems, and temperature monitoring solutions, leveraging its wide supply range, high bandwidth, and excellent thermal stability across the –40°C to +125°C temperature range.
