ADHV4702-1BCPZ-R7

Overview

The ADHV4702-1BCPZ-R7 is a high-voltage, unity-gain stable precision operational amplifier manufactured by Analog Devices Inc. It operates on supply voltages ranging from ±12 V to ±110 V dual-supply or up to 220 V asymmetrical span. The device features a typical slew rate of 74 V/µs and a small-signal bandwidth of 10 MHz. Key electrical characteristics include a maximum input offset voltage of 1 mV, a maximum input bias current of 2 pA, and a typical open-loop gain of 170 dB. It is housed in a 12-lead, 7 mm × 7 mm LFCSP package with an exposed thermal pad.

Feature Summary

• High common-mode rejection ratio and open-loop gain for precision signal processing
• Low input bias current and low input offset voltage drift for DC accuracy
• Resistor-adjustable quiescent current capability for power optimization
• Integrated shutdown mode and temperature monitor output

Applications

• High-side current sensing
• Automated test equipment
• Piezotransducers
• Digital-to-analog converter (DAC) output buffers
• Light detecting and ranging (LiDAR), avalanche photodiode (APD), single photon avalanche diode (SPAD) biasing

Procurement Notes

Verify the specific ordering suffix '-R7' against official manufacturer documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure that the component matches the exact datasheet revision required for your design constraints. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when applications require high-voltage operation up to 220 V combined supply rails alongside high precision metrics. Consider the 12-lead LFCSP package size if board space is limited. Evaluate the resistor-adjustable quiescent current feature if power consumption needs to be optimized below the standard 3 mA operating level.

Part Context

This part belongs to the ADHV4702 series of high-voltage precision amplifiers. It represents a specialized solution within Analog Devices' portfolio designed for demanding industrial and scientific environments where both high voltage handling and low noise performance are critical requirements.

Replacement Considerations
