Product details
Overview
ADA4096-4ARUZ from Analog Devices is a quad micropower rail-to-rail input/output operational amplifier with ±32 V overvoltage protection on inputs, 60 µA per amplifier supply current at ±15 V, 800 kHz unity-gain bandwidth, and 300 µV maximum offset voltage - deployed in battery monitoring, sensor conditioning, and portable instrumentation where robustness and ultra-low power are critical.
For engineers reviewing the ADA4096-4ARUZ datasheet, ADA4096-4ARUZ pinout, ADA4096-4ARUZ application, or ADA4096-4ARUZ equivalent, key selection criteria include input overvoltage tolerance beyond rails, rail-to-rail swing at 3 V to 30 V single/dual supply, guaranteed operation from −40°C to +125°C, and compatibility with capacitive loads up to 200 pF without oscillation.
Technical Context
The ADA4096-4ARUZ implements a proprietary input stage with integrated diodes enabling safe input voltage extension of ±32 V beyond supply rails without phase reversal or latch-up. Its unity-gain stable architecture supports stable closed-loop operation with gains ≥1 and handles 200 pF capacitive loads directly at the output.
It delivers 27 nV/√Hz voltage noise density and 120 dB large-signal voltage gain (at ±15 V), with PSRR >100 dB and CMRR >95 dB across full common-mode range - optimized for precision signal conditioning in noisy, wide-supply industrial and automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V single supply or ±1.5 V to ±15 V dual supply - enables direct integration into Li-ion battery-powered systems and legacy 24 V industrial rails. |
| Input Overvoltage Protection | ±32 V beyond supply rails - eliminates need for external clamping diodes in high-transient environments like automotive battery sensing. |
| Supply Current per Amplifier | 60 µA typical at ±15 V - allows 4-channel operation under 250 µA total, extending battery life in portable instrumentation. |
| Unity-Gain Bandwidth | 800 kHz at ±15 V - supports stable amplification of low-frequency sensor signals (e.g., thermocouples, strain gauges) with minimal phase lag. |
| Input Offset Voltage | 300 µV maximum - ensures ≤0.002% error in 15 V full-scale measurements, critical for precision analog front-ends. |
| Rail-to-Rail I/O Swing | Output swings within 10 mV of rails at 2 kΩ load; input common-mode extends to both rails - maximizes dynamic range in low-voltage systems. |
| Voltage Noise Density | 27 nV/√Hz at 1 kHz - preserves SNR in audio and sensor signal chains where low-noise preamplification is required. |
Pinout & Package
ADA4096-4ARUZ is packaged in a 14-lead TSSOP (RU-14) with exposed pad connected to V−. Pin 1 is OUTA; pins 2–3 are −INA/+INA; pin 4 is V+; pins 5–6 are +INB/−INB; pin 7 is OUTB; pins 8–10 are OUTC/−INC/+INC; pin 11 is V−; pins 12–14 are +IND/−IND/OUTD. Pins 13 and 14 in LFCSP variant are NIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives external load or next stage; rail-to-rail swing supports full utilization of supply headroom. |
| 2 | −INA | Inverting input of Channel A - accepts differential or single-ended signals; protected to ±32 V beyond rails. |
| 3 | +INA | Non-inverting input of Channel A - same overvoltage tolerance; used for unity-gain buffers or non-inverting configurations. |
| 4 | V+ | Positive supply rail - connects to main system supply (e.g., 3.3 V, 5 V, or ±15 V); decoupling capacitor required near pin. |
| 11 | V− | Negative supply rail - ties to GND in single-supply mode or negative rail in dual-supply; exposed pad must be soldered to this node. |
| 14 | OUTD | Amplifier D output - enables independent signal paths for multi-channel sensor arrays or redundant monitoring circuits. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal up to ±32 V beyond rails | Prevents catastrophic output latch-up during input transients - essential for battery voltage monitoring during load dump events. |
| Rail-to-rail input and output | Enables full-scale signal capture and delivery in 3 V systems without level-shifting circuitry or supply headroom loss. |
| Low 60 µA per amplifier supply current | Supports always-on sensor interfaces with <1 mA total quiescent draw for all four channels - ideal for energy-harvesting nodes. |
| Guaranteed operation from −40°C to +125°C | Validated for under-hood automotive and industrial control applications without derating or thermal management overhead. |
| Stable with 200 pF capacitive loads | Eliminates need for isolation resistors when driving ADC input filters or long PCB traces - simplifies layout and reduces BOM count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4091-4ARUZ | Lower supply current (45 µA/ch), lower GBP (150 kHz), no overvoltage protection - lacks ±32 V input tolerance. | Best suited for ultra-low-power, low-bandwidth sensor interfaces where input transients are absent. | Select ADA4091-4ARUZ only if OVP is unnecessary and bandwidth <200 kHz suffices; not drop-in compatible due to missing protection diodes. |
| AD8604ARUZ | Higher supply current (420 µA/ch), higher GBP (8 MHz), rail-to-rail I/O, but no overvoltage protection and narrower temp range (−40°C to +125°C same, but not automotive-qualified). | Preferred for higher-speed signal chains (e.g., active filters, audio line drivers) where precision and speed outweigh power and ruggedness needs. | Choose AD8604ARUZ when bandwidth >1 MHz is required and system-level transient suppression is implemented externally. |
Compared with ADA4091-4ARUZ and AD8604ARUZ, ADA4096-4ARUZ uniquely combines micropower operation, ±32 V overvoltage protection, and extended temperature performance - making it the only option among the three qualified for unclamped automotive battery monitoring and harsh industrial sensor nodes.

FAQ
What is the maximum input voltage the ADA4096-4ARUZ can tolerate without damage?
The ADA4096-4ARUZ supports an absolute maximum input voltage of (−VS) − 32 V to (+VS) + 32 V under overvoltage conditions, per its Absolute Maximum Ratings table. This means with ±15 V supplies, inputs may safely reach −47 V to +47 V. Operation outside normal common-mode range does not guarantee functional behavior, but prevents latch-up or destruction.
Does the ADA4096-4ARUZ require external components for stability with capacitive loads?
No - the ADA4096-4ARUZ is internally compensated and remains stable driving capacitive loads up to 200 pF directly at the output, as confirmed in the General Description and Typical Performance Characteristics. No series isolation resistor or external compensation network is needed for standard ADC input filtering or cable driving.
What is the operating temperature range specified for the ADA4096-4ARUZ?
The ADA4096-4ARUZ is specified for continuous operation from −40°C to +125°C across all electrical parameters, as stated in the Absolute Maximum Ratings and General Description sections. This extended industrial temperature range is validated and guaranteed - not derated - making it suitable for under-hood automotive and factory-floor applications.
Can the ADA4096-4ARUZ operate from a single 3 V supply?
Yes - the ADA4096-4ARUZ supports single-supply operation from 3 V to 30 V. At 3 V, it maintains rail-to-rail input and output swing, 465 kHz unity-gain bandwidth, and 50 µA typical supply current per amplifier, enabling use in coin-cell or single-Li-ion powered devices without voltage boosting.
Is the ADA4096-4ARUZ pin-compatible with other quad op amps in TSSOP-14 packages?
No - the ADA4096-4ARUZ has a unique pinout optimized for its overvoltage protection architecture and quad channel routing. It is not pin-compatible with industry-standard quad op amps (e.g., LM324, TL074, or AD8604). Layout redesign is required when substituting; refer to Figure 6 in the datasheet for exact pin mapping.
