ADEL2020ARZ-20-RL

Overview

The ADEL2020ARZ-20-RL7 is a high-speed current feedback operational amplifier designed for video applications. It features a 90 MHz bandwidth and a 500 V/µs slew rate. The device operates within a supply voltage range of ±3.0 V to ±18 V, consuming 6.8 mA in normal mode and 2.1 mA in power-down mode. It offers low input voltage noise of 2.9 nV/√Hz and differential gain/phase errors below 0.05%. The component includes a disable function with 100 ns turn-off time and provides an output short-circuit current of up to 150 mA.

Feature Summary

• Optimized for video line driving with minimal differential gain and phase distortion
• Integrated disable pin enables high isolation and reduced power consumption
• Capable of driving capacitive loads exceeding 1000 pF directly without oscillation

Applications

• Video line drivers
• High-speed data acquisition systems
• Multiplexer circuits requiring break-before-make switching

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the datasheet lists AR-20 and AR-20-REEL variants. Confirm that the -20-RL7 designation aligns with manufacturer documentation regarding reel specifications. Ensure compatibility with industrial temperature ranges specified for the SOIC package before finalizing procurement orders.

Selection Notes

Select this component when high bandwidth and low distortion are critical for video signal integrity. Consider the current feedback architecture which requires specific feedback resistor values to maintain stability and bandwidth. Evaluate the disable feature requirements if multiplexing or power management is necessary for the target application design.

Part Context

The ADEL2020 serves as an improved second source to the EL2020, offering enhanced dynamic specifications and lower power consumption. It belongs to Analog Devices' portfolio of high-speed amplifiers optimized for demanding analog signal processing tasks. The device is available in both PDIP and SOIC packages to accommodate various board layout constraints.

Replacement Considerations

The EL2020 is the primary predecessor model referenced in the datasheet. Verify pinout compatibility and ensure that the performance improvements in bandwidth and noise do not require circuit adjustments.
