ADA4099-2HCPZ-RL7

Overview

The ADA4099-2HCPZ-RL7 is a dual, precision, rail-to-rail input/output operational amplifier from Analog Devices. It features an ultrawide common-mode range extending to −VS − 0.1 V and +VS + 70 V, supporting supply voltages up to 50 V. The device offers low power consumption with 1.5 mA per channel typical current draw and includes a low-power shutdown mode consuming 20 µA maximum. Key electrical characteristics include an 8 MHz gain-bandwidth product, ±40 µV maximum input offset voltage, and high CMRR of 118 dB minimum.

Feature Summary

• Robust Over-The-Top operation allows inputs to exceed the positive supply rail without phase reversal
• Low quiescent current combined with a dedicated low-power shutdown pin for energy management
• High precision performance with minimal input offset voltage drift over temperature
• Integrated thermal shutdown protection and robust electrostatic discharge tolerance

Applications

• Industrial sensor conditioning in abusive environments
• Supply current sensing applications
• Battery and power supply monitoring systems
• Front-end amplifiers requiring wide common-mode ranges

Procurement Notes

Verify the specific H grade suffix ensures the extended operating temperature range of −55°C to +150°C. Confirm the CPZ package designation matches the required lead frame chip scale footprint. Ensure the RL7 suffix aligns with reel packaging requirements for automated assembly processes.

Selection Notes

Select this component when circuit designs demand simultaneous high precision and extreme voltage tolerance. The dual-channel configuration reduces board space compared to single units. Verify that the 10-lead LFCSP thermal resistance meets system dissipation limits under maximum load conditions.

Part Context

This part belongs to the ADA4099 family of robust, precision op amps designed for harsh industrial environments. It complements the single-channel ADA4099-1 by providing two channels in a compact surface-mount package. The series addresses applications requiring signal integrity near high-voltage rails.

Replacement Considerations

ADA4099-2ACPZ is available as a lower temperature grade alternative.
