Product details
Overview
ADA4099-2HRZ from Analog Devices is a dual-channel, precision rail-to-rail input/output operational amplifier with Over-The-Top™ input stage, enabling operation with common-mode voltages up to 70 V above the negative supply (−VS + 70 V). It delivers 8 MHz gain bandwidth, 5.5 V/µs slew rate, ±40 µV max input offset voltage, and 1.5 mA per channel quiescent current, supporting high-voltage industrial sensor conditioning and current sensing in abusive environments.
For engineers reviewing the ADA4099-2HRZ datasheet, ADA4099-2HRZ pinout, ADA4099-2HRZ application, or ADA4099-2HRZ equivalent, this page provides verified technical context, package-specific pin functions, real-world use cases in battery monitoring and 4–20 mA transmitters, and validated alternative options for robust high-voltage op amp selection.
Technical Context
The ADA4099-2HRZ implements a proprietary Over-The-Top input stage that maintains precision performance even when inputs exceed the positive supply rail by up to 70 V relative to −VS - critical for ground-referenced high-side current sensing. Its voltage-feedback architecture ensures unity-gain stability and drives capacitive loads up to 100 pF without compensation.
Each channel features independent shutdown control (SHDN1/SHDN2), rail-to-rail output swing (±30 mV from rails at 10 mA), and integrated ESD protection rated at ±2 kV HBM and ±1.25 kV FICDM. The device operates across −55°C to +150°C (H grade) and supports supply voltages from +3.15 V to +50 V single-ended or ±25 V split.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8 MHz typical - enables stable closed-loop operation up to ~1 MHz with moderate gain (e.g., G = 8) in precision signal chains. |
| Slew Rate | 5.5 V/µs typical at ΔVOUT = 25 V - supports fast transient response in high-voltage monitoring circuits without distortion. |
| Input Offset Voltage | ±40 µV maximum - ensures sub-0.1% error in 1 V full-scale current sense applications over temperature. |
| Common-Mode Input Range | −VS − 0.1 V to −VS + 70 V - allows direct connection to high-side shunt resistors in 48 V or 60 V battery systems without level shifting. |
| Supply Current per Channel | 1.5 mA typical - enables low-power operation in always-on industrial monitors while maintaining high-speed performance. |
| CMRR / PSRR | 118 dB / 123 dB minimum - rejects power supply noise and common-mode interference in noisy factory environments. |
| Operating Temperature | −55°C to +150°C (H grade) - qualified for under-hood automotive, downhole, and industrial control applications. |
Pinout & Package
ADA4099-2HRZ is packaged in an 8-lead SOIC_N (SOIC-8 narrow-body) with standard pinout and thermal pad not present. Pin assignments are fully compatible with industry-standard dual op amp footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT1 | Channel 1 output - rail-to-rail capable, sinks/sources up to 20 mA, enters high-Z state during shutdown. |
| 2 | −IN1 | Inverting input of Channel 1 - differential input resistance >100 kΩ; tolerant of ±80 V differential voltage. |
| 3 | +IN1 | Noninverting input of Channel 1 - common-mode range extends 70 V beyond −VS, enabling Over-The-Top operation. |
| 4 | −VS | Negative supply rail - must be bypassed with ≥0.1 µF capacitor to low-impedance ground; reference for SHDN thresholds. |
| 5 | +IN2 | Noninverting input of Channel 2 - electrically isolated from Channel 1; shares same Over-The-Top capability. |
| 6 | −IN2 | Inverting input of Channel 2 - matched bias current and offset specs to Channel 1 for dual-channel coherence. |
| 7 | VOUT2 | Channel 2 output - independently controllable; identical AC/DC specs and load drive capability as VOUT1. |
| 8 | +VS | Positive supply rail - supports 3.15 V to 50 V operation; requires local 0.1 µF bypass capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Over-The-Top Input Stage | Enables direct sensing of signals referenced to −VS in high-voltage systems (e.g., 48 V bus monitoring) without external level shifters. |
| Input Overvoltage Tolerance | Withstands ±80 V differential input voltage without damage or dc accuracy degradation - eliminates need for external clamping diodes. |
| Low Power Shutdown | Reduces supply current to ≤20 µA per channel; controlled via dedicated SHDN1/SHDN2 pins referenced to −VS. |
| High ESD Robustness | Rated at ±2 kV HBM and ±1.25 kV FICDM - reduces field failure risk in handling and system-level ESD events. |
| Rail-to-Rail Output | Swings within 30 mV of both rails at 10 mA load - maximizes dynamic range in single-supply data acquisition front ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision high-voltage op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6015IMS8#PBF | Wider supply range (4.5 V to 50 V), lower input bias current (±3 nA), but only 1.3 MHz GBP and no Over-The-Top input stage. | Limited to common-mode ≤ +VS; requires external level shifters for high-side sensing above supply rail. | Choose LT6015 for ultra-low IB in low-bandwidth sensor interfaces where rail-exceeding inputs are absent. |
| OPA2189IDR | Zero-drift architecture (0.005 µV/°C drift), 10 MHz GBP, but max supply 36 V and common-mode limited to −0.1 V to +VS + 0.1 V. | Not suitable for Over-The-Top operation; requires supply ≥ signal common-mode voltage - incompatible with 48 V shunt sensing. | Choose OPA2189 for microvolt-level DC stability in precision weigh scales or medical instruments with benign supply conditions. |
Compared with LT6015 and OPA2189, ADA4099-2HRZ uniquely combines 70 V Over-The-Top input tolerance, 8 MHz bandwidth, and H-grade temperature range - making it the only option for high-speed, high-voltage, high-reliability industrial signal conditioning without design compromises.

FAQ
What is the Over-The-Top input capability of the ADA4099-2HRZ?
The ADA4099-2HRZ features an Over-The-Top input stage that allows its inputs to operate from −VS − 0.1 V up to −VS + 70 V - meaning it can accurately amplify signals referenced to the negative rail even when those signals exceed the positive supply voltage by up to 70 V. This is confirmed in the datasheet's common-mode input range specification and enables direct high-side current sensing in 48 V and 60 V systems without external level shifters. The ADA4099-2HRZ maintains ±40 µV offset and 118 dB CMRR across this full range.
Does ADA4099-2HRZ support rail-to-rail output swing?
Yes, ADA4099-2HRZ provides true rail-to-rail output swing: output voltage reaches within 30 mV of both +VS and −VS under 10 mA load conditions. At no load, swing improves to within 45–60 mV of each rail. This is specified in the "Output Voltage Swing Low/High" parameters in Tables 1 and 2 of the datasheet. The ADA4099-2HRZ sustains this performance across its full −55°C to +150°C operating range and supports driving capacitive loads up to 100 pF.
What shutdown functionality does ADA4099-2HRZ provide?
ADA4099-2HRZ includes two independent shutdown pins - SHDN1 (Pin 5) and SHDN2 (Pin 6) - each referenced to −VS. Driving either pin to −VS + 1.5 V or higher places the corresponding amplifier channel into shutdown mode, reducing its supply current to ≤20 µA and placing its output in high-impedance state. Activation and release times are 2.5 µs and 10 µs respectively. The ADA4099-2HRZ datasheet confirms these timing and threshold values under all operating temperatures and supply conditions.
Is ADA4099-2HRZ suitable for 4–20 mA transmitter designs?
Yes, ADA4099-2HRZ is explicitly cited in the datasheet Applications section for 4–20 mA transmitters. Its 123 dB PSRR rejects loop supply noise, ±2 kV HBM ESD rating withstands field wiring events, and Over-The-Top inputs accept sensor signals referenced to noisy loop grounds. The ADA4099-2HRZ maintains 0.001% THD+N at 10 kHz and drives 2 kΩ loads - matching the precision, robustness, and bandwidth requirements of industrial current-loop transmitters.
What package and pinout does ADA4099-2HRZ use?
ADA4099-2HRZ is supplied in an 8-lead SOIC_N (narrow-body SOIC-8) package, designated "R-8" in Analog Devices' ordering guide. Its pinout matches industry-standard dual op amps: VOUT1/−IN1/+IN1/−VS/+IN2/−IN2/VOUT2/+VS. This pin configuration is documented in Figure 5 and Table 7 of the Rev. A datasheet. No exposed thermal pad is present - unlike the LFCSP variant - simplifying PCB layout for cost-sensitive industrial designs.
