Product details
Overview
ADA4099-1BUJZ-R5 from Analog Devices is a single-channel, precision rail-to-rail input/output operational amplifier with Over-The-Top™ architecture, enabling operation with input voltages up to 70 V above the negative supply rail. 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 across a +3.15 V to +50 V supply range. It is designed for high-voltage industrial sensor conditioning and current sensing in abusive environments.
For engineers reviewing the ADA4099-1BUJZ-R5 datasheet, ADA4099-1BUJZ-R5 pinout, ADA4099-1BUJZ-R5 application, or ADA4099-1BUJZ-R5 equivalent, key selection considerations include its −VS − 0.1 V to −VS + 70 V common-mode range, robust ±2 kV HBM ESD rating, shutdown capability (20 µA max), and guaranteed performance over −55°C to +150°C (H grade).
Technical Context
The ADA4099-1BUJZ-R5 employs a proprietary Over-The-Top input stage that maintains precision DC performance even when inputs exceed the positive supply by up to 70 V relative to −VS, with no phase reversal under overdrive. Its voltage-feedback topology supports unity-gain stability and drives capacitive loads up to 100 pF while delivering 20 mA output current per channel.
It integrates low-power shutdown (2.5 µs active-to-shutdown response), rail-to-rail output swing (within 45 mV of rails at no load), and high PSRR (123 dB min) and CMRR (118 dB min). Input protection tolerates ±80 V differential voltage without damage or dc accuracy degradation.
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. |
| Slew Rate | 5.5 V/µs typical at ΔVOUT = 25 V - supports fast settling for high-dV/dt signals in power monitoring. |
| Input Offset Voltage | ±40 µV maximum - ensures sub-0.1% error in precision current sense applications at 1 V full-scale. |
| 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/36 V/48 V rails and wide-input power supplies. |
| Quiescent Current | 1.5 mA per channel typical - balances performance and power efficiency in always-on monitoring circuits. |
| ESD Rating | ±2 kV HBM, ±1.25 kV FICDM - meets IEC 61000-4-2 Level 3 for robustness in factory-floor instrumentation. |
Pinout & Package
The ADA4099-1BUJZ-R5 is housed in a 6-lead thin small outline transistor (TSOT) package (UJ-6), optimized for high-density PCB layouts and thermal performance on JEDEC 4-layer boards (θJA = 192°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Amplifier Output | Delivers rail-to-rail output swing; capable of sourcing/sinking 20 mA; high-impedance in shutdown mode. |
| 2 - −VS | Negative Power Supply | Reference for all internal circuitry; must be bypassed with ≥0.1 µF capacitor to low-impedance ground plane. |
| 3 - +IN | Noninverting Input | High-impedance node (>1 GΩ common-mode); tolerant of Over-The-Top voltages up to −VS + 70 V. |
| 4 - −IN | Inverting Input | Differential input node; supports precision feedback networks; immune to phase reversal during overdrive. |
| 5 - SHDN | Shutdown Control | Logic-controlled enable: < −VS + 0.5 V = active; > −VS + 1.5 V = shutdown (20 µA IQ); 10 µs wake-up time. |
| 6 - +VS | Positive Power Supply | Primary supply rail; requires ≥0.1 µF local bypass; supports up to 50 V continuous operation. |
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 resistive dividers. |
| Robust Input Protection | Tolerates ±80 V differential input voltage without damage or parametric shift - critical for fault-prone industrial interfaces. |

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 IQ (1.3 mA), but narrower CMR (−VS to +VS + 7 V) and no Over-The-Top capability. | Limited to standard high-side sensing where input stays within 7 V of +VS; unsuitable for true 48 V bus monitoring. | Select LT6015 only if Over-The-Top operation is unnecessary and lower quiescent current is prioritized. |
| OPA192IDBVR | Lower offset (±5 µV), higher GBP (10 MHz), but CMR limited to −VS − 0.1 V to +VS + 0.1 V and no 70 V overvoltage tolerance. | Requires external level-shifting for high-side sensing; lacks robustness against transient overvoltage events. | Choose OPA192 only for ultra-precision, low-noise lab-grade instrumentation where supply rails are tightly controlled. |
Compared with LT6015IMS8#PBF and OPA192IDBVR, the ADA4099-1BUJZ-R5 uniquely combines 70 V Over-The-Top input tolerance, −55°C to +150°C operation, and ±40 µV offset in a 6-lead TSOT - making it the only drop-in solution for unconditioned high-voltage industrial sensing without redesign.

FAQ
What is the maximum continuous supply voltage for the ADA4099-1BUJZ-R5?
The ADA4099-1BUJZ-R5 supports a maximum continuous supply voltage of +50 V, with transient tolerance up to +60 V. This rating is defined by time-dependent dielectric breakdown limits of on-chip oxides. Operation beyond 50 V DC risks long-term reliability degradation, though short-duration overshoots within the ±60 V absolute maximum are survivable.
Does the ADA4099-1BUJZ-R5 support true Over-The-Top operation, and what does that mean in practice?
Yes, the ADA4099-1BUJZ-R5 supports true Over-The-Top operation: its inputs function correctly with common-mode voltages extending from −VS − 0.1 V to −VS + 70 V - i.e., up to 70 V above the negative supply rail. In practice, this allows direct high-side current sensing on 48 V buses without level-shifting circuitry, maintaining ±40 µV offset accuracy even at VCM = 70 V.
What is the operating temperature range specified for the ADA4099-1BUJZ-R5?
The ADA4099-1BUJZ-R5 is rated for operation from −55°C to +150°C (H grade), with full parametric specifications guaranteed across this range. This includes key parameters such as input offset voltage (±90 µV max), offset drift (±0.8 µV/°C max), and PSRR (119 dB min), making it suitable for under-hood automotive, downhole, and industrial furnace applications.
Can the ADA4099-1BUJZ-R5 drive capacitive loads, and what is the maximum supported value?
Yes, the ADA4099-1BUJZ-R5 is designed to drive capacitive loads up to 100 pF while maintaining stability and specified settling time (1.5 µs for 0.1%). This capability supports direct connection to ADC input capacitors or long PCB traces without external isolation resistors - simplifying layout in compact sensor front-ends.
How does the shutdown feature of the ADA4099-1BUJZ-R5 work, and what is its quiescent current in that state?
The ADA4099-1BUJZ-R5 features a dedicated SHDN pin (Pin 5) that places the amplifier in low-power shutdown when driven above −VS + 1.5 V, reducing supply current to 20 µA maximum. The output enters high-impedance state, and wake-up time from shutdown to active is 10 µs. This enables power-gating in battery-powered or energy-conscious industrial nodes without compromising signal chain integrity.
