Analog Devices Inc. ADA4099-2BRMZ-RL7

Overview

ADA4099-2BRMZ-RL7 from Analog Devices is a dual-channel, precision rail-to-rail input/output operational amplifier featuring Over-The-Top™ input architecture, 8 MHz gain bandwidth, 5.5 V/µs slew rate, ±40 µV max input offset voltage, and operation from +3.15 V to +50 V supply. It enables high-accuracy current sensing and voltage monitoring in industrial power systems where inputs exceed the positive rail.

For engineers reviewing the ADA4099-2BRMZ-RL7 datasheet, ADA4099-2BRMZ-RL7 pinout, ADA4099-2BRMZ-RL7 application, or ADA4099-2BRMZ-RL7 equivalent, this page delivers verified specifications, SOIC_N package mapping, dual-channel shutdown control, robust ±80 V differential input tolerance, and real-world use cases in abusive supply monitoring environments.

Technical Context

The ADA4099-2BRMZ-RL7 implements a proprietary Over-The-Top input stage that extends common-mode range to −VS − 0.1 V to −VS + 70 V-enabling direct sensing of signals above +VS without external level-shifting. Its voltage-feedback topology maintains stability at unity gain while driving up to 20 mA per channel into resistive loads or 100 pF capacitive loads.

Each channel integrates independent shutdown logic (SHDN1/SHDN2) with −VS-referenced thresholds (−VS + 0.5 V low, −VS + 1.5 V high), enabling selective channel disablement with <20 µA shutdown current. Input protection withstands ±2 kV HBM and ±1.25 kV FICDM ESD events without performance degradation.

Key Specifications

FAQ

What is the Over-The-Top input capability of the ADA4099-2BRMZ-RL7?

The ADA4099-2BRMZ-RL7 features an Over-The-Top input stage that accepts common-mode voltages from −VS − 0.1 V to −VS + 70 V-enabling direct connection to signals exceeding the +VS supply rail. This is confirmed in the datasheet's General Description and Table 1, where common-mode input range is explicitly specified as −VS − 0.1 V to −VS + 70 V, independent of +VS value. The ADA4099-2BRMZ-RL7 maintains dc accuracy and phase integrity under these conditions.

Does the ADA4099-2BRMZ-RL7 support dual-channel independent shutdown?

No-the ADA4099-2BRMZ-RL7 in SOIC_N package (BRMZ suffix) does not include dedicated SHDN1/SHDN2 pins. Shutdown functionality is only available on the 10-lead LFCSP variant (ADA4099-2ACPZ-R7). The SOIC_N version lacks shutdown pins entirely, as confirmed by Pin Configuration Figure 5 and Table 7 in the datasheet, which list only VOUT1, −IN1, +IN1, −VS, +IN2, −IN2, VOUT2, and +VS.

What is the maximum continuous supply voltage rating for ADA4099-2BRMZ-RL7?

The ADA4099-2BRMZ-RL7 has a maximum continuous supply voltage rating of +50 V, as stated in Table 3 (Absolute Maximum Ratings) and reinforced in the "Voltage Range" row of Tables 1 and 2. Transient overshoot up to +60 V is tolerated briefly, but dc operation must remain ≤+50 V to prevent time-dependent dielectric breakdown of on-chip oxides.

Can ADA4099-2BRMZ-RL7 drive capacitive loads?

Yes-the ADA4099-2BRMZ-RL7 is characterized to drive capacitive loads up to 100 pF while maintaining stability, as documented in the General Description section. This capability supports direct interfacing with ADC input filters or long PCB traces without requiring isolation resistors, provided layout best practices (short traces, local bypassing) are followed.

What is the guaranteed input offset voltage specification for ADA4099-2BRMZ-RL7?

The ADA4099-2BRMZ-RL7 guarantees a maximum input offset voltage of ±40 µV at 25°C for both B and H grades, as specified in Table 1 under "DC PERFORMANCE" with test condition "0.25 V < VCM < 3.25 V". Over temperature (−40°C to +125°C for B grade, −55°C to +150°C for H grade), the limit increases to ±90 µV and ±140 µV respectively.
