Product details
Overview
ADA4098-1BUJZ-R5 from Analog Devices is a single-channel, precision rail-to-rail input/output operational amplifier featuring Over-The-Top™ architecture. It operates from 3 V to 50 V supply, delivers 1.05 MHz gain bandwidth, draws only 165 µA per channel, and supports ultrawide common-mode input range (−VS − 0.1 V to −VS + 70 V), enabling direct sensing in high-side current monitoring applications.
For engineers reviewing the ADA4098-1BUJZ-R5 datasheet, ADA4098-1BUJZ-R5 pinout, ADA4098-1BUJZ-R5 application, or ADA4098-1BUJZ-R5 equivalent, this device is selected for robust front-end amplification where input overvoltage tolerance, low drift (±0.5 µV/°C max), and operation beyond rail in abusive industrial environments are mandatory design requirements.
Technical Context
The ADA4098-1BUJZ-R5 implements an Over-The-Top™ input stage that maintains precision performance with common-mode voltages up to 70 V above the negative rail - independent of positive supply voltage - and tolerates ±80 V differential input without damage or phase reversal. Its input stage uses high-voltage JFET-based circuitry enabling <700 pA input bias current and >1 GΩ common-mode input resistance.
Internally, it integrates a low-power shutdown control (SHDN pin) with 2.5 µs activation time and 30 µs wake-up latency, and features thermal shutdown at 175°C junction temperature with 20°C hysteresis. The amplifier is unity-gain stable and drives capacitive loads up to 200 pF while delivering 20 mA output current per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 50 V DC - enables single-supply operation in battery-powered and industrial 24–48 V systems without level-shifting. |
| Gain Bandwidth Product | 1.05 MHz typical - supports stable closed-loop gain configurations up to ~100× at 10 kHz with adequate phase margin. |
| Input Offset Voltage | ±35 µV maximum (B grade) - ensures sub-0.1 mV error in 20 mV full-scale current sense applications. |
| Common-Mode Input Range | −VS − 0.1 V to −VS + 70 V - allows direct high-side sensing across 70 V potential above ground, e.g., in 48 V bus monitoring. |
| Supply Current per Channel | 165 µA typical - enables always-on precision sensing in power-constrained IoT and portable equipment. |
| Input Offset Drift | ±0.5 µV/°C maximum (B grade) - limits offset drift to <10 µV over 20°C ambient variation, critical for uncalibrated long-term measurements. |
| CMRR | 120 dB minimum (−0.1 V to +70 V) - rejects common-mode noise in noisy industrial signal chains without calibration. |
Pinout & Package
The ADA4098-1BUJZ-R5 is housed in a 6-lead thin small outline transistor (TSOT) package (UJ-6), with exposed pad thermally connected to −VS. This compact 1.5 mm × 1.5 mm footprint supports high-density PCB layouts and efficient heat dissipation in space-constrained modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Amplifier Output | Low-impedance buffered output capable of sourcing/sinking 20 mA; rail-to-rail swing with <15 mV headroom at no load. |
| 2 - −VS | Negative Power Supply | Reference node for all internal circuitry; must be bypassed with ≥0.1 µF capacitor to low-impedance ground plane. |
| 3 - +IN | Noninverting Input | High-impedance, low-bias-current node optimized for precision differential or single-ended sensing topologies. |
| 4 - −IN | Inverting Input | High-impedance feedback node; immune to phase reversal when overdriven up to ±80 V differential. |
| 5 - SHDN | Shutdown Control | Logic-controlled enable/disable: <−VS + 0.5 V = active; >−VS + 1.5 V = shutdown (20 µA quiescent). |
| 6 - +VS | Positive Power Supply | Primary supply rail; requires local ≥0.1 µF bypass capacitor to minimize PSRR degradation at high frequencies. |
Key Features
| Feature | Design Value |
|---|---|
| Over-The-Top™ Input Stage | Enables reliable operation with inputs up to 70 V above −VS - eliminating need for external level shifters in high-side current sensing. |
| Robust Input Protection | Withstands ±3 kV HBM / ±1.25 kV FICDM ESD and ±80 V differential input without accuracy degradation or latch-up. |
| Ultra-Low Power Shutdown | Reduces supply current to ≤20 µA per channel while maintaining high-impedance output state - ideal for duty-cycled sensor nodes. |
| Wide Temperature Range Support | Specified from −55°C to +150°C (H grade); B grade operates from −40°C to +125°C - suitable for under-hood and industrial control environments. |
| Low 1/f Noise Corner | 6 Hz typical - preserves signal integrity in DC-coupled, low-frequency applications such as strain gauge or thermocouple conditioning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4077-1ARZ-R7 | Lower supply current (100 µA), narrower common-mode range (−VS to +VS + 2 V), no Over-The-Top capability | Suitable for rail-to-rail but non-abusive environments; cannot replace ADA4098-1BUJZ-R5 in >5 V above rail sensing | Select when ultra-low power dominates over input overvoltage tolerance and system voltage headroom is limited. |
| LT6015IMS8#PBF | Wider supply range (up to 50 V), but lower GBP (1.3 MHz), higher offset drift (±2 µV/°C), no guaranteed shutdown mode | Acceptable for general-purpose high-voltage amplification, but lacks robust Over-The-Top validation and precise low-drift spec | Choose only if thermal stability over wide temperature ranges is less critical than raw bandwidth in non-safety-critical designs. |
Compared with ADA4077-1ARZ-R7 and LT6015IMS8#PBF, the ADA4098-1BUJZ-R5 uniquely combines 70 V Over-The-Top input tolerance, ±0.5 µV/°C drift, and 20 µA shutdown current - making it the sole option for uncalibrated, high-reliability current sensing in 48 V industrial systems.

FAQ
What is the maximum common-mode input voltage supported by the ADA4098-1BUJZ-R5?
The ADA4098-1BUJZ-R5 supports a guaranteed common-mode input range from −VS − 0.1 V to −VS + 70 V. This Over-The-Top™ capability allows the device to operate with inputs up to 70 V above the negative supply rail - verified across temperature and process corners per datasheet Table 1 and Figure 25. It is not limited by the +VS rail voltage, enabling true high-side sensing in 48 V systems without external level shifting.
Does the ADA4098-1BUJZ-R5 include a shutdown function, and how is it controlled?
Yes, the ADA4098-1BUJZ-R5 includes a dedicated SHDN pin (Pin 5). The amplifier remains active when SHDN is tied to −VS or left floating (with recommended 1 nF capacitor to −VS). It enters low-power shutdown mode when SHDN voltage exceeds −VS + 1.5 V, reducing supply current to ≤20 µA. Wake-up time is 30 µs, and shutdown activation occurs within 2.5 µs - fully documented in datasheet Sections "SHDN AND SHDNx PINS" and Figure 4.
Can the ADA4098-1BUJZ-R5 drive capacitive loads, and what is the maximum value?
Yes, the ADA4098-1BUJZ-R5 is characterized to drive capacitive loads up to 200 pF while maintaining stability and specified settling time (18 µs for 0.1% at ±2 V step). This capability is confirmed in the General Description section and validated across test conditions in Typical Performance Characteristics (Figure 39 shows loop gain/phase margin). For loads >200 pF, external isolation resistor or compensation network is required.
What is the input protection rating of the ADA4098-1BUJZ-R5, and is it suitable for harsh ESD environments?
The ADA4098-1BUJZ-R5 is rated for ±3 kV Human Body Model (HBM) and ±1.25 kV Field-Induced Charged Device Model (FICDM) per JEDEC JS-001/JS-002 standards - verified in production testing and listed in Table 5. Its Over-The-Top™ input stage also withstands ±80 V differential input continuously without damage or parametric shift, making it suitable for deployment in unshielded industrial enclosures and field-connected sensor interfaces.
Is the ADA4098-1BUJZ-R5 qualified for operation at extreme temperatures, and what grade does it ship as?
The ADA4098-1BUJZ-R5 is manufactured and tested to the B grade specification, supporting operation from −40°C to +125°C ambient temperature. While the H grade (−55°C to +150°C) exists in the family, the BUJZ-R5 variant is B grade - confirmed in the Ordering Guide and Absolute Maximum Ratings table. Thermal shutdown activates at 175°C junction temperature with 20°C hysteresis, providing fail-safe protection during overload conditions.
