Analog Devices Inc. ADA4096-2WARMZ-R7

Overview

ADA4096-2WARMZ-R7 from Analog Devices is a dual micropower rail-to-rail input/output operational amplifier with ±32 V overvoltage protection on inputs, 60 µA supply current per amplifier at ±15 V, 800 kHz unity-gain bandwidth, and guaranteed operation from −40°C to +125°C. It serves as a robust signal conditioner in battery monitoring and portable instrumentation where supply headroom is limited and input fault tolerance is critical.

For engineers reviewing the ADA4096-2WARMZ-R7 datasheet, ADA4096-2WARMZ-R7 pinout, ADA4096-2WARMZ-R7 application, or ADA4096-2WARMZ-R7 equivalent, this page delivers verified specifications, automotive-grade package details (8-lead MSOP), real-world use scenarios, and validated alternative options for low-power, high-voltage-tolerant op amp selection.

Technical Context

The ADA4096-2WARMZ-R7 employs a proprietary input stage with integrated diode clamps that enable safe operation with input voltages extending 32 V beyond either supply rail-without phase reversal or latch-up. Its rail-to-rail input common-mode range spans from V− − 0.1 V to V+ + 0.1 V, and output swing reaches within 14 mV of each rail under light load (10 kΩ).

It features unity-gain stability across its full 3 V to 30 V single-supply or ±1.5 V to ±15 V dual-supply range, with 27 nV/√Hz voltage noise density and 120 dB large-signal voltage gain at ±15 V. The device handles capacitive loads up to 200 pF without oscillation and supports stable operation with 100% duty-cycle overload recovery.

FAQ

What is the maximum input voltage the ADA4096-2WARMZ-R7 can tolerate without damage?

The ADA4096-2WARMZ-R7 supports input voltages up to (V+) + 32 V and (V−) − 32 V under overvoltage conditions, as specified in Absolute Maximum Ratings. This protection is enabled by internal clamping diodes and remains functional across the full −40°C to +125°C operating range. The ADA4096-2WARMZ-R7 does not require external series resistors for basic overvoltage survival in battery disconnect or jump-start scenarios.

Is the ADA4096-2WARMZ-R7 pin-compatible with other variants in the ADA4096 family?

Yes-the ADA4096-2WARMZ-R7 shares identical pinout and footprint with the standard ADA4096-2ARMZ-R7 (same 8-lead MSOP package). Both variants use Pin 1 = OUTA, Pin 2 = −INA, Pin 3 = +INA, Pin 4 = V−, Pin 5 = +INB, Pin 6 = −INB, Pin 7 = OUTB, Pin 8 = V+. The "W" suffix denotes AEC-Q100 qualification but does not alter pin function or layout.

Does the ADA4096-2WARMZ-R7 require external compensation for unity-gain stability?

No-the ADA4096-2WARMZ-R7 is internally compensated for unity-gain stability across its full supply range (3 V to 30 V). It drives capacitive loads up to 200 pF without oscillation and maintains ≥51° phase margin at ±15 V. No external compensation components are needed for standard non-inverting or inverting configurations with gains ≥1.

How does the ADA4096-2WARMZ-R7 perform in single-supply 3.3 V applications?

At 3.3 V single supply (V+ = 3.3 V, V− = GND), the ADA4096-2WARMZ-R7 delivers rail-to-rail input (0 V to 3.3 V) and output (≤15 mV from rails at 10 kΩ), 465 kHz unity-gain bandwidth, and 60 µA supply current. Input offset voltage remains ≤500 µV over −40°C to +125°C, supporting accurate low-voltage sensor interfacing in IoT edge nodes.

What thermal considerations apply to the ADA4096-2WARMZ-R7 in automotive under-hood environments?

The ADA4096-2WARMZ-R7 in 8-lead MSOP has θJA = 142°C/W on a 4-layer JEDEC board. With 120 µA total supply current (60 µA × 2), power dissipation is ~0.4 mW at 3.3 V - resulting in negligible self-heating. Its −40°C to +125°C rating and exposed pad (tied to V−) ensure reliable operation in under-hood ambient temperatures up to 105°C.
