Typical Applications
ADA4807-2ARMZ is suitable for 6 applications: Portable Instrumentation, Active Filters, ADC Driver, Video Signal Processing, Battery-Powered Devices, Test and Measurement.
Portable Instrumentation
The ADA4807-2ARMZ's low quiescent current (1 mA per amp) and rail-to-rail I/O make it ideal for battery-powered handheld meters and data loggers. Its 180 MHz bandwidth ensures accurate amplification of fast sensor signals, while the low noise (3.1 nV/√Hz) preserves signal integrity in precision measurements. The small 8-MSOP package saves board space in compact designs.
Recommended
Active Filters
With a gain bandwidth product of 180 MHz, the ADA4807-2ARMZ can implement active filters with cutoff frequencies up to tens of MHz. Its low noise and high slew rate (225 V/µs) minimize distortion in filter responses. The rail-to-rail output allows maximum signal swing in single-supply filter designs, making it suitable for anti-aliasing filters in communication systems.
Recommended
ADC Driver
The ADA4807-2ARMZ is optimized for driving high-resolution ADCs. Its low noise (3.1 nV/√Hz) and high bandwidth (180 MHz) ensure that the ADC's performance is not degraded by the driver. The rail-to-rail output can swing close to the ADC's reference rails, maximizing dynamic range. The disable pin (on LFCSP version) allows power saving between conversions.
Recommended
Video Signal Processing
The 180 MHz bandwidth and 225 V/µs slew rate of the ADA4807-2ARMZ make it suitable for video buffering and distribution. It can drive coaxial cables with minimal signal degradation, and its low differential gain/phase errors ensure accurate color reproduction. The low power consumption is beneficial in multi-channel video systems.
Recommended
Battery-Powered Devices
The ADA4807-2ARMZ's 1 mA quiescent current per amplifier extends battery life in portable devices such as medical monitors and wireless sensors. Its rail-to-rail I/O allows operation from a single 3.3 V supply without headroom issues. The small MSOP package is ideal for space-constrained PCBs in wearables and IoT devices.
Recommended
Test and Measurement
In test equipment, the ADA4807-2ARMZ provides high bandwidth and low noise for signal conditioning in oscilloscopes, spectrum analyzers, and data acquisition systems. Its fast settling time and low distortion ensure accurate measurement of high-frequency signals. The dual-channel configuration saves space in multi-channel instruments.

Key Differentiators
- Lowest noise among high-speed rail-to-rail amplifiers (vs OPA2863A)
- Higher bandwidth than ADA4805-2 (vs ADA4805-2TRMZ-EP)
- Lower power consumption than ADA4897-2 (vs ADA4897-2ARMZ-RL)
Design Notes
The ADA4807-2ARMZ operates from 2.7V to 5V single supply or ±1.35V to ±2.5V dual supply. Ensure the supply voltage does not exceed the absolute maximum rating of 6V. Use 0.1µF ceramic capacitors close to the V+ and V- pins for decoupling, and a 10µF bulk capacitor for low-frequency stability.
For optimal noise performance, keep the feedback resistors low (e.g., 1kΩ or less) to minimize thermal noise. Place the amplifier close to the signal source and ADC to reduce trace inductance. Use a solid ground plane and avoid routing high-speed digital traces near the analog inputs.
The MSOP package does not include the disable (PD) pin; it is only available on the LFCSP version (ADA4807-2ACPZ). If you need the disable feature, use the LFCSP variant. Also, the ADA4807-2 is not unity-gain stable for gains less than 1; ensure a minimum gain of 1 to avoid oscillation.
