ADA4099-2BCPZ

Overview

The ADA4099-2BCPZ is a dual precision operational amplifier from Analog Devices, featuring an 8 MHz gain bandwidth product and a typical slew rate of 5.5 V/µs. It operates on supply voltages ranging from +3.15 V to +50 V with a quiescent current of 1.5 mA per channel. The device supports Over-The-Top operation, allowing input common-mode voltages up to −VS + 70 V. Key electrical specifications include a maximum input offset voltage of ±40 µV, a minimum large signal voltage gain of 120 dB, and a CMRR of 118 dB. It is housed in an 8-lead SOIC package.

Feature Summary

• Supports Over-The-Top operation for inputs exceeding the positive supply rail
• Provides robust performance with high ESD tolerance ratings
• Features low power shutdown capability for energy conservation
• Ensures stability when driving capacitive loads

Applications

• Industrial sensor conditioning circuits
• Supply current sensing applications
• Battery and power supply monitoring systems
• Front-end amplifiers in abusive environments
• 4 mA to 20 mA transmitter interfaces

Procurement Notes

Verify the specific grade suffix (B or H) required for your temperature range needs, as the B grade typically covers -40°C to +125°C while the H grade extends to -55°C to +150°C. Confirm that the 8-lead SOIC_N package matches your PCB footprint requirements. Ensure that the selected variant includes the necessary shutdown pin configuration if low-power standby modes are part of your system design.

Selection Notes

Select this component when high voltage tolerance and over-the-top input capabilities are required alongside precision DC characteristics. It is suitable for designs needing unity-gain stability and low noise in single-supply or split-supply configurations. Consider the thermal resistance values provided in the datasheet for proper heat dissipation planning in enclosed industrial enclosures.

Part Context

This dual-channel version belongs to the ADA4099 family of robust, precision op amps designed for demanding industrial environments. The series combines high speed with low offset voltage drift, making it ideal for applications where signal integrity must be maintained despite significant common-mode voltage excursions beyond standard supply rails.

Replacement Considerations

Check for ADA4099-2ACPZ or ADA4099-2ARMZ for alternative package options such as MSOP or LFCSP. Verify functional compatibility with ADA4099-1 variants if only a single channel is needed.
