What are the key features of AD8066ARM?
- 100 dB minimum common-mode rejection ratio (CMRR) ensures excellent interference rejection in differential signal acquisition and instrumentation amplifier front ends
- Ultra-low input bias current of 0.006 µA at 25°C minimizes offset errors in high-impedance sensor interfaces and photodiode transimpedance amplifiers
- Dual-channel voltage-feedback architecture in an 8-pin MSOP package reduces board area and BOM count in two-channel signal conditioning circuits
- Internal frequency compensation simplifies design by eliminating external compensation networks while maintaining stability across the full gain range
What is AD8066ARM used for?
The AD8066ARM is well-suited for precision instrumentation front ends where its 100 dB CMRR and 0.006 µA input bias current enable accurate differential measurements from low-impedance sensors such as strain gauges and load cells. Its dual-channel configuration in the compact 8-pin MSOP package makes it ideal for stereo audio signal conditioning and active filter stages in portable test equipment. The voltage-feedback topology with internal frequency compensation also supports transimpedance amplifier designs for photodiode-based optical receivers and current-to-voltage converters.

Frequently Asked Questions
What input bias current does the AD8066ARM specify at 25°C, and why does that matter for high-impedance sensors?
The AD8066ARM has an input bias current of 0.006 µA (6 nA) at 25°C. When driving a 1 MΩ source impedance, this generates only 6 mV of offset voltage, which is negligible compared to most sensor full-scale outputs. This makes it suitable for photodiode and electrostatic sensor interfaces where source impedances exceed 100 kΩ.
How does the 100 dB CMRR of AD8066ARM help in differential measurement circuits exposed to 50 Hz or 60 Hz interference?
With a minimum CMRR of 100 dB, the AD8066ARM attenuates common-mode noise — including 50 Hz or 60 Hz mains interference — by a factor of 100,000:1. A 1 V RMS common-mode noise signal is reduced to just 10 µV at the output, which is well below the threshold of most 12-bit ADC systems with full-scale ranges of 1 V or more.
When is the AD8066ARM a suitable alternative to the AD8067 single-channel amplifier for dual-channel designs?
The AD8066ARM integrates 2 amplifier circuits in a single 8-pin MSOP package, replacing two AD8067 single-channel ICs and reducing the required board footprint from roughly 2 × 5 mm² to approximately 3 mm × 3 mm. This substitution saves at least one MSOP-8 placement, cuts soldering defect risk, and can reduce dual-channel bill of materials cost by 20-30% in volume production.
Does the AD8066ARM require external compensation capacitors for stability in unity-gain follower configurations?
No, the AD8066ARM includes internal frequency compensation, so no external capacitors are needed for stability in unity-gain or higher-gain follower configurations. This simplifies PCB layout by eliminating 2 compensation capacitors per channel, reducing the 8-pin MSOP design to just supply bypass capacitors on the 15 V or 5 V rails.
