Product details
Overview
ADA4096-4ARUZ-R7 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 operation from ±1.5 V to ±15 V (3 V to 30 V single-supply). It serves as a robust signal conditioner in battery monitoring systems where input transients exceed supply rails.
For engineers reviewing the ADA4096-4ARUZ-R7 datasheet, ADA4096-4ARUZ-R7 pinout, ADA4096-4ARUZ-R7 application, or ADA4096-4ARUZ-R7 equivalent, key selection criteria include overvoltage tolerance beyond rails, micropower consumption under 100 µA per channel, rail-to-rail I/O swing, guaranteed operation across −40°C to +125°C, and compatibility with capacitive loads up to 200 pF without compensation.
Technical Context
The ADA4096-4ARUZ-R7 implements a proprietary input stage with integrated diodes enabling safe input voltage extension of ±32 V beyond the supply rails without phase reversal or latch-up. Its unity-gain stable architecture supports direct use in gain-of-1 configurations without external compensation.
It delivers 27 nV/√Hz voltage noise density and 120 dB large-signal voltage gain at ±15 V, while maintaining rail-to-rail output swing within 14 mV of each rail at 10 kΩ load - critical for low-voltage precision sensing in portable instrumentation and automotive subsystems.
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 interface with Li-ion, 12 V automotive, and industrial 24 V systems. |
| Input Overvoltage Protection | ±32 V beyond supply rails - eliminates need for external clamping diodes in battery voltage monitoring with transient surges. |
| Supply Current per Amplifier | 60 µA typical at ±15 V - supports multi-channel always-on sensing with sub-250 µA total quiescent current. |
| Unity-Gain Bandwidth | 800 kHz at ±15 V - sufficient for DC-coupled sensor buffering and anti-aliasing filtering up to ~100 kHz. |
| Input Offset Voltage | 300 µV maximum - ensures ≤0.3 mV error in 10 V full-scale measurements without trimming. |
| Operating Temperature Range | −40°C to +125°C - qualified for under-hood automotive and industrial control environments. |
| Voltage Noise Density | 27 nV/√Hz at 1 kHz - preserves SNR in low-level thermocouple or bridge sensor interfaces. |
Pinout & Package
The ADA4096-4ARUZ-R7 is packaged in a 14-lead TSSOP (RU-14) with exposed pad connected to V−. Pin 13 is not internally connected (NIC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | −INA | Inverting input of Channel A - accepts signals up to ±32 V beyond V+ or V− without damage or phase reversal. |
| 2 | +INA | Non-inverting input of Channel A - high-impedance node (±25 nA bias current) for precision reference or sensor connections. |
| 3 | V+ | Positive supply rail - must be decoupled with ≥0.1 µF ceramic capacitor near pin for stability. |
| 4 | OUTB | Output of Channel B - rail-to-rail swing supports full dynamic range utilization in single-supply data acquisition. |
| 5 | −INB | Inverting input of Channel B - matched offset voltage (≤300 µV max) enables accurate differential amplification. |
| 6 | +INB | Non-inverting input of Channel B - identical CMRR (≥86 dB at ±5 V) to Channel A for common-mode rejection. |
| 7 | OUTA | Output of Channel A - capable of sourcing/sinking ±10 mA, supporting direct drive of 10 kΩ loads to rails. |
| 8 | OUTC | Output of Channel C - independent output stage with same slew rate (0.4 V/µs at ±15 V) as other channels. |
| 9 | −INC | Inverting input of Channel C - shares same overvoltage protection structure as Channels A/B/D. |
| 10 | +INC | Non-inverting input of Channel C - matched input capacitance (CDM = 2.5 pF) minimizes phase shift in high-frequency feedback paths. |
| 11 | V− | Negative supply rail - exposed pad must be soldered to this net for thermal and electrical performance. |
| 12 | +IND | Non-inverting input of Channel D - supports four independent sensor channels in compact layout. |
| 13 | NIC | No internal connection - left unconnected; no pull-up/down required. |
| 14 | OUTD | Output of Channel D - fully specified for rail-to-rail swing and 100 dB channel separation at 1 kHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum input voltage the ADA4096-4ARUZ-R7 can tolerate without damage?
The ADA4096-4ARUZ-R7 supports an overvoltage condition of (−V−) − 32 V ≤ VIN ≤ (+V+) + 32 V, meaning it withstands inputs up to 32 V beyond either supply rail. For example, with ±15 V supplies, inputs from −47 V to +47 V are tolerated. This rating applies only under overvoltage conditions per the Absolute Maximum Ratings table; normal operation remains within the supply rails.
Does the ADA4096-4ARUZ-R7 require external compensation for unity-gain stability?
No, the ADA4096-4ARUZ-R7 is unity-gain stable and requires no external compensation components. Its internal compensation ensures stable operation with closed-loop gains ≥1, including voltage followers and non-inverting amplifiers with gain = 1. This simplifies design and reduces bill-of-materials cost in sensor interface circuits.
Can the ADA4096-4ARUZ-R7 drive a 10 kΩ load to the supply rails?
Yes, the ADA4096-4ARUZ-R7 delivers rail-to-rail output swing. At ±15 V supply and RL = 10 kΩ, VOH = 14.94 V and VOL = −14.80 V - within 150 mV of each rail. At ±5 V, output reaches ±4.97 V. This capability enables full utilization of ADC input ranges in single- or dual-supply systems without level-shifting circuitry.
What is the thermal resistance (θJA) of the ADA4096-4ARUZ-R7 in its 14-lead TSSOP package?
The ADA4096-4ARUZ-R7 in the 14-lead TSSOP (RU-14) package has a junction-to-ambient thermal resistance (θJA) of 112°C/W when mounted on a 4-layer JEDEC-standard PCB with zero airflow and the exposed pad soldered to V−. This value assumes proper thermal land design per Analog Devices' layout guidelines.
Is the ADA4096-4ARUZ-R7 qualified for automotive applications?
The ADA4096-4ARUZ-R7 is not explicitly automotive-qualified; only the ADA4096-2W variant is AEC-Q100 qualified. However, the ADA4096-4ARUZ-R7 operates across −40°C to +125°C and meets all electrical specifications in that range, making it suitable for non-safety-critical automotive subsystems such as cabin sensors and infotainment power management when validated per customer requirements.
