ADA4097-2BRZ-RL7

Overview

The ADA4097-2BRZ-RL7 is a dual-channel, precision operational amplifier manufactured by Analog Devices Inc. It features an ultrawide common-mode input range extending from −VS to +VS and beyond, supporting Over-The-Top operation up to 70 V above the negative supply. The device operates on a wide power supply voltage range of +3 V to +50 V (±25 V for PSRR) with a typical supply current of 32.5 µA per channel. Key electrical specifications include a maximum input offset voltage of ±60 µV, a gain bandwidth product of 130 kHz, and a slew rate of 0.1 V/µs. It offers high CMRR and PSRR, low noise characteristics, and robust ESD protection.

Feature Summary

• Over-The-Top capability allows inputs to operate from −VS to +VS and beyond, tolerating voltages up to 70 V above the negative rail without phase reversal.
• Robust construction provides high electrostatic discharge tolerance and large signal voltage gain for reliable performance in abusive environments.
• Low quiescent power consumption combined with high precision parameters ensures efficient operation in battery-powered and portable instrumentation applications.

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 transmitters

Procurement Notes

Verify that the specific ordering suffix matches the required package type and reel configuration. Confirm the grade (B or H) aligns with the necessary temperature range and offset voltage drift specifications. Ensure compatibility with the intended supply voltage and common-mode requirements before finalizing procurement.

Selection Notes

Select this component when high precision is required alongside extreme common-mode voltage ranges exceeding standard supply rails. Consider the B grade for tighter offset voltage limits or the H grade for extended temperature operation up to +150°C. Evaluate the shutdown feature availability if lower power states are needed, noting it is only available in specific packages like LFCSP.

Part Context

This part belongs to the ADA4097 family of robust, precision op amps designed for single-supply and split-supply applications. It complements other Analog Devices precision amplifiers by offering unique Over-The-Top input capabilities while maintaining low power consumption and high accuracy suitable for demanding industrial and automotive environments.

Replacement Considerations

Direct substitutes within the same family include the ADA4097-2ARMZ (MSOP package) and ADA4097-2BCPZ (LFCSP package). Verify pinout compatibility and thermal resistance differences when transitioning between SOIC_N, MSOP, and LFCSP packages.

FAQ

Does the ADA4097-2BRZ-RL7 support shutdown functionality?

No, the 8-lead SOIC_N package does not include shutdown pins. Shutdown functionality is only available in the 6-lead TSOT and 10-lead LFCSP packages.

What is the maximum operating voltage for this device?

The continuous maximum operating supply voltage is 50 V. The device can tolerate temporary transient overshoot up to 60 V.
