Product details
Overview
ADA4097-1HUJZ-RL7 from Analog Devices is a single-channel, precision rail-to-rail input/output operational amplifier with Over-The-Top™ architecture, enabling operation with common-mode inputs up to 70 V above the negative supply. It delivers ±60 µV max input offset voltage, 130 kHz gain bandwidth, and 32.5 µA typical supply current per channel, supporting high-voltage industrial sensor conditioning and battery monitoring in harsh environments.
For engineers reviewing the ADA4097-1HUJZ-RL7 datasheet, ADA4097-1HUJZ-RL7 pinout, ADA4097-1HUJZ-RL7 application, or ADA4097-1HUJZ-RL7 equivalent, this page provides verified specifications, TSOT-6 package details, shutdown functionality, robust ±2 kV HBM ESD rating, and real-world use cases in abusive overvoltage conditions - all confirmed from Analog Devices Rev. A datasheet.
Technical Context
The ADA4097-1HUJZ-RL7 implements an Over-The-Top™ input stage that tolerates differential input voltages up to ±80 V and common-mode voltages from −VS − 0.1 V to −VS + 70 V, independent of +VS. Its input protection includes internal clamping and robust ESD structures rated at ±2 kV HBM and ±1.25 kV FICDM.
This op amp features unity-gain stability, drives capacitive loads up to 200 pF, and supports output currents up to ±30 mA. The integrated shutdown pin (Pin 5) enables low-power mode with 20 µA max quiescent current and 100 µs wake-up time, while maintaining high-impedance output during shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

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 |
|---|---|---|---|
| ADA4077-1ARZ-R7 | Lower supply current (10 µA), narrower common-mode range (−VS to +VS), no Over-The-Top™ capability | Limited to standard rail-to-rail sensing; unsuitable for >±VS input overvoltage scenarios | Select when ultra-low power dominates and input voltage stays within supply rails |
| LT6015IMS8#PBF | Wider GBP (1.3 MHz), higher supply current (95 µA), same 76 V input range but no shutdown pin | Higher bandwidth for faster signals; lacks power management for intermittent operation | Select when dynamic response matters more than shutdown control or sub-40 µA quiescent current |
Compared with ADA4097-1HUJZ-RL7, ADA4077-1ARZ-R7 trades Over-The-Top™ robustness for lower power, while LT6015IMS8#PBF offers higher speed at the cost of quiescent current and missing shutdown - making ADA4097-1HUJZ-RL7 optimal for low-power, high-CMRR, high-reliability industrial monitoring.

FAQ
What is the maximum continuous supply voltage for ADA4097-1HUJZ-RL7?
The ADA4097-1HUJZ-RL7 supports a maximum continuous supply voltage of +50 V, limited by time-dependent dielectric breakdown (TDDB) of on-chip oxides. Transient overshoot up to +60 V is tolerated briefly, but dc operation must remain ≤+50 V to ensure long-term reliability and parametric stability per Analog Devices Rev. A datasheet Section "Absolute Maximum Ratings".
Does ADA4097-1HUJZ-RL7 support true rail-to-rail input and output operation?
Yes, ADA4097-1HUJZ-RL7 provides rail-to-rail input and output operation, with common-mode input range extending from −VS − 0.1 V to −VS + 70 V and output swing within 15 mV of either rail under no-load conditions. This Over-The-Top™ capability allows direct interface with high-side shunts and unregulated supplies without external level shifting.
What is the function of Pin 5 (SHDN) on ADA4097-1HUJZ-RL7?
Pin 5 is the shutdown control input for ADA4097-1HUJZ-RL7. When pulled to −VS + 1.5 V or higher, the amplifier enters low-power shutdown mode (≤20 µA supply current) and its output goes high-impedance. At −VS + 0.5 V or lower - or when floating - the device remains active. Activation delay is 100 µs; deactivation delay is 2.5 µs.
Can ADA4097-1HUJZ-RL7 operate in automotive under-hood environments?
Yes, ADA4097-1HUJZ-RL7 is qualified for operation from −55°C to +150°C (H grade) and features ±2 kV HBM ESD rating, thermal shutdown at 175°C, and robust input protection - making it suitable for under-hood automotive applications such as battery management, exhaust gas sensing, and engine control modules where high temperature and electrical stress are present.
What package type is used for ADA4097-1HUJZ-RL7?
ADA4097-1HUJZ-RL7 uses a 6-lead Thin Small Outline Transistor (TSOT) package (UJ-6), measuring 1.5 mm × 1.0 mm with an exposed pad. The exposed pad must be soldered to −VS for optimal thermal performance and EMI suppression, and the package supports JEDEC-standard reflow profiles per Analog Devices datasheet Section "Outline Dimensions".
