Battery-Powered Medical Devices
In medical devices like glucose monitors and pulse oximeters, power efficiency is critical. The ADA4805-1AKSZ consumes only 500 µA, extending battery life. Its low offset drift (0.2 µV/°C) ensures accurate signal processing over temperature variations. The rail-to-rail output allows full-scale signals to be digitized by ADCs without additional gain stages.
Recommended
Active Filters
The ADA4805-1AKSZ's 105 MHz bandwidth and 170 V/µs slew rate make it suitable for active filters in communication and audio systems. Its low quiescent current is advantageous in multi-channel filter banks. The rail-to-rail output allows filters to operate at lower supply voltages without clipping, preserving signal integrity.
Recommended
ADC Driver Circuits
The ADA4805-1AKSZ is ideal for driving high-resolution ADCs due to its low noise and high slew rate. It can settle quickly to 16-bit accuracy, ensuring accurate conversion. The rail-to-rail output maximizes the ADC's input range, and the low quiescent current reduces thermal drift in precision systems.
Recommended
Video Signal Processing
With 105 MHz bandwidth and 170 V/µs slew rate, the ADA4805-1AKSZ can handle composite video signals. Its low power consumption is beneficial in portable video equipment. The rail-to-rail output ensures full video swing, and the small SC70 package is ideal for compact camera modules.
Recommended
Industrial Control Systems
The ADA4805-1AKSZ operates over -40°C to +125°C, making it suitable for industrial environments. Its wide supply range (3 V to 10 V) allows use in 24 V systems with proper regulation. The low offset drift ensures accurate process control, and the rail-to-rail output interfaces directly with ADCs in PLCs and sensors.

Key Differentiators
- Lowest quiescent current in its class (vs ADA4807-1AKSZ-R2)
- Higher bandwidth than AD8615 (vs AD8615AKSZ-R2)
- Lower offset drift than AD8615 (vs AD8615AKSZ-R2)
Design Notes
The ADA4805-1AKSZ operates from 3 V to 10 V supplies. Use 0.1 µF ceramic capacitors close to the V+ and V- pins for decoupling. For single-supply operation, ensure the input common-mode range is not exceeded; the device is not rail-to-rail input, so keep inputs within the specified range.
The SC70-6 package has a thermal resistance of approximately 200°C/W. For high-power applications, ensure adequate copper area on the PCB to dissipate heat. Keep traces short to minimize parasitic capacitance, which can affect high-frequency performance.
Do not exceed the absolute maximum supply voltage of 12 V. The output can swing close to the rails but not exactly to them; leave headroom for load conditions. Also, avoid driving capacitive loads greater than 100 pF without a series resistor, as this can cause instability.
Compliance Information
RoHS compliant per Analog Devices product page. No AEC-Q100 qualification indicated.
