ADA4098-2BCPZ-RL7

Overview

The ADA4098-2BCPZ-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 supply voltages up to 50 V. The device offers low power consumption with a typical supply current of 165 µA per channel. Key electrical specifications include a gain-bandwidth product of 1.05 MHz, a slew rate of 0.85 V/µs, and a maximum input offset voltage of ±35 µV for the B grade. It provides high CMRR (120 dB minimum) and PSRR (123 dB minimum), along with robust overdrive tolerance without phase reversal.

Feature Summary

• Over-The-Top operation allows inputs to function above the positive supply rail
• Robust design tolerant to abusive environments and large signal overdrives
• Low noise performance with a 1/f noise corner at 6 Hz
• Integrated shutdown capability for reduced power consumption

Applications

• Industrial sensor conditioning
• Supply current sensing
• Battery and power supply monitoring
• Front-end amplifiers in abusive environments
• 4 mA to 20 mA transmitters

Procurement Notes

Verify the specific package variant against the datasheet ordering guide, as the BCPZ suffix indicates a Lead Frame Chip Scale Package. Confirm that the B grade selection meets the required offset voltage drift specifications for the application. Ensure ESD precautions are followed during handling due to the sensitivity of the CMOS input stages. Cross-reference the RL7 suffix for reel packaging requirements if applicable to the manufacturing process.

Selection Notes

Select this component when high DC precision is required alongside wide input voltage ranges exceeding standard supply rails. The B grade is suitable for applications demanding tight offset voltage limits and low drift. Consider the thermal resistance characteristics of the LFCSP package for heat dissipation planning. Evaluate the shutdown pin functionality if power management during idle states is necessary for the system design.

Part Context

This part belongs to the ADA4098 family of robust, precision op amps designed for challenging industrial environments. The dual-channel configuration (ADA4098-2) integrates two identical amplifiers into a single compact package. It complements the single-channel ADA4098-1 and other variants within the series, offering a balance of speed, precision, and power efficiency for analog signal processing tasks.

Replacement Considerations

Check the official Analog Devices related products list for direct functional equivalents or upgraded revisions. Verify pin compatibility and electrical parameter overlaps before substituting with other precision amplifiers. Ensure any alternative maintains the Over-The-Top input capability and similar supply voltage ratings.
