Product details
Overview
ADA4099-1HUJZ-RL7 from Analog Devices is a single-channel, robust precision operational amplifier with Over-The-Top™ input architecture, enabling operation from −VS − 0.1 V to −VS + 70 V common-mode voltage. It delivers 8 MHz gain bandwidth, 5.5 V/µs slew rate, ±40 µV max input offset voltage, and 1.5 mA per channel supply current. It is designed for high-voltage industrial sensor conditioning and current sensing in abusive environments.
For engineers reviewing the ADA4099-1HUJZ-RL7 datasheet, ADA4099-1HUJZ-RL7 pinout, ADA4099-1HUJZ-RL7 application, or ADA4099-1HUJZ-RL7 equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options - all grounded in Analog Devices' Rev. A datasheet and official ordering guide.
Technical Context
The ADA4099-1HUJZ-RL7 implements a proprietary Over-The-Top input stage that tolerates differential input voltages up to ±80 V and supports rail-to-rail-plus common-mode operation beyond the negative rail by up to 70 V - independent of positive supply voltage. Its voltage-feedback topology ensures unity-gain stability and drives capacitive loads up to 100 pF.
It integrates a dedicated shutdown pin (Pin 5) with logic thresholds referenced to −VS (−VS + 0.5 V low, −VS + 1.5 V high), enabling low-power mode with ≤20 µA quiescent current. Input protection includes ±2 kV HBM and ±1.25 kV FICDM ESD ratings, and thermal shutdown activates at 175°C junction temperature.
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 noise gain. |
| Slew Rate | 5.5 V/µs typical at ΔVOUT = 25 V - supports fast transient response in high-voltage current sensing. |
| Input Offset Voltage | ±40 µV maximum - ensures sub-0.1% error in 1 V/A current sense amplifiers over temperature. |
| Common-Mode Range | −VS − 0.1 V to −VS + 70 V - allows direct sensing of high-side currents in 48 V battery systems without level-shifting. |
| Supply Voltage Range | +3.15 V to +50 V (single-supply) - compatible with industrial 24 V and telecom 48 V rails. |
| Quiescent Current | 1.5 mA per channel typical - balances performance and power in always-on monitoring circuits. |
| CMRR / PSRR | 118 dB / 123 dB minimum - rejects supply and common-mode noise in noisy plant-floor environments. |
Pinout & Package
The ADA4099-1HUJZ-RL7 is housed in a 6-lead thin small outline transistor (TSOT) package (UJ-6), with an exposed pad thermally connected to −VS. This compact 1.5 mm × 1.5 mm footprint supports high-density PCB layouts in space-constrained industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Amplifier output | Capable of sourcing/sinking 20 mA; rail-to-rail swing within 45 mV of rails (no load). |
| 2 - −VS | Negative power supply | Reference for all internal biasing; must be bypassed with ≥0.1 µF capacitor to low-impedance ground plane. |
| 3 - +IN | Noninverting input | High-impedance node (>1 GΩ common-mode resistance); tolerant of overvoltage up to +80 V relative to −VS. |
| 4 - −IN | Inverting input | Differential input pair node; supports Over-The-Top operation with matched input bias current (±10 nA max). |
| 5 - SHDN | Shutdown control | Active-high logic referenced to −VS; pulls output to high-impedance state when > −VS + 1.5 V. |
| 6 - +VS | Positive power supply | Accepts up to 50 V continuous; requires local ≥0.1 µF bypass capacitor to minimize supply noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Over-The-Top input stage | Enables direct high-side current sensing in 48 V systems without external level shifters or isolated supplies. |
| Robust input protection | Tolerates ±80 V differential input and −5 V to +80 V absolute pin voltage - survives accidental wiring faults. |
| Low 1/f noise corner | 6 Hz typical - preserves signal integrity in DC-coupled sensor interfaces (e.g., strain gauges, RTDs). |
| Wide temperature range | −55°C to +150°C (H grade) - qualified for under-hood automotive and downhole industrial use. |
| Shutdown current | ≤20 µA - reduces system standby power in battery-backed or energy-harvested monitoring nodes. |
Applications

Use Value: Survives ±2 kV HBM ESD events and maintains dc accuracy after 80 V differential overvoltage transients - no calibration drift. |
Use Scenario: Signal conditioning for vibration sensors mounted on industrial motors operating in high EMI, wide ambient temperature, and mechanical shock conditions. IC Role / Device Role / Timing Role: Low-drift, low-noise amplifier with extended common-mode range for direct connection to floating sensor elements.

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), but lower GBP (1.3 MHz) and higher input offset (±75 µV max). | Limited to lower-bandwidth sensor interfaces; unsuitable for fast current transients or high-gain AC-coupled stages. | Choose LT6015 for ultra-low input bias current (±25 pA) in high-impedance pH or photodiode circuits - not for speed-critical current sensing. |
| OPA192IDBVR | Lower supply current (1 mA), but narrower common-mode range (−0.1 V to +VS − 1.5 V) and no Over-The-Top capability. | Requires level-shifting or dual-supply configuration for high-side sensing above +VS - adds complexity and error sources. | Choose OPA192 only for low-power, single-supply rail-to-rail I/O applications where input voltage never exceeds supply rails. |
Compared with LT6015IMS8#PBF and OPA192IDBVR, the ADA4099-1HUJZ-RL7 uniquely combines 70 V over-the-negative-rail input tolerance, 8 MHz bandwidth, and ±40 µV offset - making it the only option for precision, high-speed, high-common-mode industrial current sensing without auxiliary circuitry.

FAQ
What is the maximum continuous supply voltage for ADA4099-1HUJZ-RL7?
The ADA4099-1HUJZ-RL7 supports a maximum continuous supply voltage of +50 V, as specified in its Absolute Maximum Ratings table. 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. This rating applies across the full −55°C to +150°C operating temperature range.
Does ADA4099-1HUJZ-RL7 support true rail-to-rail input and output operation?
Yes - the ADA4099-1HUJZ-RL7 features rail-to-rail input and output operation, with an extended common-mode input range from −VS − 0.1 V to −VS + 70 V (Over-The-Top™). Its output swings within 45 mV of both rails under no-load conditions and maintains linearity while sourcing/sinking up to 20 mA per channel.
How does the SHDN pin function on ADA4099-1HUJZ-RL7?
The SHDN pin (Pin 5) on ADA4099-1HUJZ-RL7 is a −VS-referenced active-high shutdown control. When pulled above −VS + 1.5 V, the amplifier enters low-power mode (<20 µA supply current) and the output transitions to high impedance. When tied to −VS or left open (with optional 1 nF cap to −VS), the device remains fully active. Response time is 2.5 µs (active→shutdown) and 10 µs (shutdown→active).
Can ADA4099-1HUJZ-RL7 be used in high-temperature automotive under-hood applications?
Yes - the ADA4099-1HUJZ-RL7 is rated for −55°C to +150°C operation (H grade), with thermal shutdown activation at 175°C junction temperature. Its guaranteed parametric performance, ±0.4 µV/°C offset drift, and ±2 kV HBM ESD rating make it suitable for engine control unit (ECU) sensor interfaces, exhaust gas recirculation (EGR) monitoring, and other under-hood applications demanding long-term reliability.
What is the noise performance of ADA4099-1HUJZ-RL7 at low frequencies?
The ADA4099-1HUJZ-RL7 delivers 150 nV p-p input-referred voltage noise over 0.1 Hz to 10 Hz, with a 6 Hz 1/f noise corner. At 100 Hz, its broadband noise is 7 nV/√Hz. These values are measured under standard conditions (5 V supply, 25°C) and remain stable across Over-The-Top operation - critical for precision DC measurements in industrial instrumentation.
