Typical Applications
ADA4807-1AKSZ-RL7 is suitable for 6 applications: Portable Instrumentation, Battery-Powered Audio, Active Filters, ADC Driver, Photodiode Amplifier, Industrial Sensor Interface.
Portable Instrumentation
The ADA4807-1AKSZ-RL7's low power (1 mA) and low noise (3.1 nV/√Hz) make it ideal for battery-powered multimeters, data loggers, and handheld test equipment. Its rail-to-rail output maximizes dynamic range on 3.3 V supplies, and the small SC-70 package saves board space. The high bandwidth (180 MHz) ensures accurate amplification of fast transient signals, while the disable pin allows power saving between measurements.
Recommended
Battery-Powered Audio
With a quiescent current of only 1 mA and a supply range down to 2.7 V, the ADA4807-1AKSZ-RL7 is well-suited for portable audio devices such as MP3 players, smartphones, and hearing aids. Its low noise (3.1 nV/√Hz) ensures a clean audio signal, and the rail-to-rail output allows maximum headroom on low voltages. The 180 MHz bandwidth supports high-quality audio processing without slew-rate limiting.
Recommended
Active Filters
The ADA4807-1AKSZ-RL7's high gain bandwidth product (180 MHz) and low distortion make it an excellent choice for active filters in communication and instrumentation systems. It can implement Butterworth, Chebyshev, or Bessel filters with cutoff frequencies up to tens of MHz. The rail-to-rail input/output allows full-scale signal processing on low supplies, and the low noise ensures high signal-to-noise ratio in the passband.
Recommended
ADC Driver
The ADA4807-1AKSZ-RL7 can drive high-speed ADCs with its 60 mA output current and 180 MHz bandwidth. Its low noise and low distortion preserve signal integrity, while the rail-to-rail output maximizes the ADC's dynamic range. The disable pin allows power saving when the ADC is idle. It is suitable for driving 12-bit ADCs with sampling rates up to 100 MSPS.
Recommended
Photodiode Amplifier
The ADA4807-1AKSZ-RL7's low current noise (0.7 pA/√Hz) and low voltage noise (3.1 nV/√Hz) make it ideal for transimpedance amplifiers used in optical sensors, LIDAR, and medical diagnostics. The high bandwidth (180 MHz) allows fast pulse detection, and the low input bias current minimizes DC offset. The rail-to-rail output provides wide dynamic range for varying light levels.
Recommended
Industrial Sensor Interface
In industrial environments, the ADA4807-1AKSZ-RL7 can condition signals from temperature, pressure, and strain sensors. Its wide operating temperature range (-40°C to +125°C) and low power make it suitable for remote sensors. The rail-to-rail input allows direct interface with sensors that output near the supply rails, and the high bandwidth supports fast data acquisition.

Key Differentiators
- Lowest noise among high-speed RRIO amplifiers (vs OPA836)
- Integrated disable pin for power saving (vs OPA836)
- Lower quiescent current than comparable parts (vs LMH6643)
Design Notes
The ADA4807-1AKSZ-RL7 operates from 2.7 V to 5 V single supply. Use a 0.1 µF ceramic capacitor close to the V+ pin and a 10 µF bulk capacitor for low-frequency decoupling. For dual-supply operation, ensure both supplies are symmetrical and decoupled similarly.
For optimal noise performance, keep the feedback network components close to the amplifier and use a ground plane. Avoid routing high-speed digital traces near the input pins. The SC-70 package has a thermal pad; solder it to the PCB for improved heat dissipation.
The disable pin is active low. If unused, tie it to V+ to prevent accidental shutdown. Do not exceed the absolute maximum supply voltage of 6 V. Also, ensure the input common-mode voltage does not exceed the rails by more than 0.3 V to avoid latch-up.
Compliance Information
RoHS and REACH compliant per distributor data. Not AEC-Q100 qualified.
