ADA4700-1ARDZ-R7

Overview

The ADA4700-1ARDZ-R7 is a high voltage, precision operational amplifier manufactured by Analog Devices Inc. It features a single-channel design housed in an 8-SOIC package with an exposed pad. The device supports a wide operating supply voltage range from ±5 V to ±50 V and delivers a typical output current drive of 30 mA. Key electrical parameters include a low input offset voltage of 0.2 mV, a high slew rate of 20 V/µs, and a gain bandwidth product of 3.5 MHz. It operates within an ambient temperature range of −40°C to +85°C.

Feature Summary

• Features thermal regulation at junction temperatures exceeding 145°C for protection against excessive power dissipation.
• Provides unity-gain stability and phase inversion-free performance across the specified operating conditions.
• Includes integrated short-circuit protection and current limiting capabilities.

Applications

• Automated and bench top test equipment
• High voltage regulators and power amplifiers
• Data acquisition and signal conditioning systems
• Piezo drivers and predrivers

Procurement Notes

Verify the specific ordering suffix R7 corresponds to the required tape and reel packaging configuration before procurement. Confirm that the 8-SOIC-EP package dimensions align with the target PCB footprint. Ensure the supply voltage requirements fall within the ±5 V to ±50 V operational range to maintain specified performance characteristics.

Selection Notes

Select this component when applications require both high voltage handling and precision DC performance. The device is suitable for designs needing rail-to-rail output swing to maximize signal-to-noise ratios. Consider the exposed pad requirement for proper thermal management and connection to the negative supply plane during circuit layout.
