Product details
Overview
ADA4097-1BUJZ-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 ADA4097-1BUJZ-RL7 datasheet, ADA4097-1BUJZ-RL7 pinout, ADA4097-1BUJZ-RL7 application, or ADA4097-1BUJZ-RL7 equivalent, this page provides verified specifications, TSOT-6 package details, shutdown functionality, robust overvoltage tolerance (±80 V differential, −10 V to +80 V input), and real-world use cases in abusive supply-sensing circuits.
Technical Context
The ADA4097-1BUJZ-RL7 implements an Over-The-Top™ input stage that extends common-mode range beyond the negative rail by up to 70 V while maintaining precision performance-enabling direct sensing of high-side currents or battery voltages without level-shifting. Its input stage tolerates ±80 V differential voltage and features ±2 kV HBM ESD protection.
It integrates a dedicated SHDN pin (Pin 5) for low-power shutdown (20 µA max), with logic thresholds referenced to −VS (active below −VS + 0.5 V, shutdown above −VS + 1.5 V). The amplifier remains unity-gain stable and drives capacitive loads up to 200 pF while delivering 20 mA output sink/source capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +3 V to +50 V (single-supply); supports abusive 70 V CM input beyond −VS |
| Input Offset Voltage | ±60 µV maximum (B grade), enabling <100 µV total error in precision current sense |
| Gain Bandwidth Product | 130 kHz typical at fTEST = 250 Hz - sufficient for DC-coupled sensor signal chains |
| Slew Rate | 0.1 V/µs typical (ΔVOUT = 4 V) - adequate for slow-varying industrial signals |
| Supply Current per Channel | 32.5 µA typical active, 20 µA max shutdown - enables always-on monitoring in low-power systems |
| Common-Mode Input Range | −VS − 0.1 V to −VS + 70 V - allows direct high-side sensing in 48 V battery or industrial bus applications |
| CMRR / PSRR | 120 dB min CMRR (−0.1 V to +70 V), 123 dB min PSRR (+3 V to ±25 V) - rejects supply and common-mode noise in noisy environments |
Pinout & Package
ADA4097-1BUJZ-RL7 is housed in a 6-lead Thin Small Outline Transistor (TSOT) package (UJ-6), optimized for space-constrained industrial PCBs and featuring an exposed pad thermally connected to −VS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VOUT | Amplifier output | Delivers rail-to-rail output swing; high-impedance during shutdown |
| 2 - −VS | Negative power supply | Reference for all biasing; must be bypassed with ≥0.1 µF capacitor to low-impedance ground |
| 3 - +IN | Noninverting input | High-impedance node (>1 GΩ common-mode resistance); tolerant of overvoltage when used in Over-The-Top configuration |
| 4 - −IN | Inverting input | High-impedance node; differential input voltage rated to ±80 V |
| 5 - SHDN | Shutdown control | Logic-referenced to −VS; asserts shutdown at >−VS + 1.5 V; floating or tied to −VS enables operation |
| 6 - +VS | Positive power supply | Must be bypassed with ≥0.1 µF capacitor to low-impedance ground; supports up to +50 V continuous |
Key Features
| Feature | Design Value |

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 CM range (−VS to +VS + 5 V), no Over-The-Top capability | Not suitable for >5 V beyond rail sensing; limited to standard rail-to-rail input use cases | Select when ultra-low power dominates over high common-mode range requirements |
| LT6015IMS8#PBF | Wider GBP (1.3 MHz), higher supply current (95 µA), same 70 V Over-The-Top CM range, but no shutdown pin | Lacks integrated shutdown; requires external enable logic for power gating | Select when higher bandwidth is needed and board space allows discrete shutdown control |
Compared with ADA4077-1ARZ-R7 and LT6015IMS8#PBF, the ADA4097-1BUJZ-RL7 uniquely balances ultra-low quiescent current (32.5 µA), 70 V Over-The-Top input, and integrated shutdown in a 6-lead TSOT - making it optimal for space- and power-constrained high-voltage monitoring.

FAQ
What is the maximum continuous supply voltage for ADA4097-1BUJZ-RL7?
The ADA4097-1BUJZ-RL7 supports a maximum continuous supply voltage of +50 V, as defined by time-dependent dielectric breakdown limits of on-chip oxides. Transient overshoot up to +60 V is tolerated per absolute maximum ratings, but DC operation must remain ≤+50 V. This rating applies regardless of whether the device is operated in single-supply (+VS to −VS) or split-supply (±VS) configurations.
Does ADA4097-1BUJZ-RL7 support true rail-to-rail input and output operation?
Yes, the ADA4097-1BUJZ-RL7 provides rail-to-rail input and output operation - but its defining feature is Over-The-Top™ input capability, allowing the common-mode voltage to extend up to 70 V above the −VS rail. Input range is specified from −VS − 0.1 V to −VS + 70 V, and output swings within 15 mV of each rail under no load, meeting true rail-to-rail performance across its full operating temperature range.
How does the SHDN pin on ADA4097-1BUJZ-RL7 function, and what are its voltage thresholds?
The SHDN pin (Pin 5) on ADA4097-1BUJZ-RL7 controls amplifier enable/disable with thresholds referenced to −VS: amplifier is active when VSHDN < −VS + 0.5 V, and enters shutdown when VSHDN > −VS + 1.5 V. During shutdown, supply current drops to ≤20 µA and output goes high-impedance. Floating or tying SHDN directly to −VS enables normal operation; a 1 nF capacitor to −VS is recommended if routing near noisy nodes.
Can ADA4097-1BUJZ-RL7 be used for high-side current sensing in a 48 V system?
Yes - the ADA4097-1BUJZ-RL7 is explicitly designed for this use case. With a common-mode input range extending to −VS + 70 V, it can directly interface with the high-side of a 48 V bus (e.g., VBAT = +48 V, −VS = 0 V) while maintaining precision performance. Its ±80 V differential input rating and input overvoltage tolerance ensure robustness against transients commonly seen in automotive and industrial 48 V architectures.
What is the guaranteed input offset voltage drift specification for ADA4097-1BUJZ-RL7?
The ADA4097-1BUJZ-RL7 B-grade guarantees input offset voltage drift of ±1 µV/°C maximum over the full operating temperature range (−40°C to +125°C). This value is lab-characterized and applies across the entire common-mode input range (−0.1 V to +70 V relative to −VS), ensuring predictable DC error accumulation in precision measurement applications like RTD or bridge sensor interfaces.
