Analog Devices Inc. ADA4096-2WARMZ-RL

Overview

ADA4096-2WARMZ-RL from Analog Devices is a dual, 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 −40°C to +125°C automotive-grade operation - used in battery monitoring circuits where robustness against supply transients and low quiescent power are critical.

For engineers reviewing the ADA4096-2WARMZ-RL datasheet, ADA4096-2WARMZ-RL pinout, ADA4096-2WARMZ-RL application, or ADA4096-2WARMZ-RL equivalent, this page delivers verified specifications, package-validated pin functions, automotive-qualified thermal performance, and real-world sensor conditioning use cases - all aligned to Rev. G datasheet and MSOP-8 packaging.

Technical Context

The ADA4096-2WARMZ-RL implements a proprietary overvoltage-protected input stage that prevents phase reversal when inputs exceed supply rails by up to ±32 V, enabling direct connection to unregulated battery or industrial sensor nodes without external clamping. Its rail-to-rail input common-mode range extends from V− − 0.1 V to V+ + 0.1 V, and output swing reaches within 14 mV of rails at ±15 V with 10 kΩ load.

It operates stably from single 3 V to 30 V or dual ±1.5 V to ±15 V supplies, features 27 nV/√Hz voltage noise density at 1 kHz, and drives capacitive loads up to 200 pF without compensation - making it suitable for high-impedance sensor buffering and low-power analog front-ends in harsh environments.

Key Specifications

Pinout & Package

FAQ

What is the maximum input voltage the ADA4096-2WARMZ-RL can withstand without damage?

The ADA4096-2WARMZ-RL supports input voltages up to (V−) − 32 V and (V+) + 32 V under overvoltage conditions, per Absolute Maximum Ratings Table 5. This is enabled by internal protection diodes and a unique input stage that prevents phase reversal. Operation outside normal supply rails is allowed only during fault conditions - continuous operation at these extremes is not specified.

Is the ADA4096-2WARMZ-RL pin-compatible with other ADA4096-2 variants?

Yes - the ADA4096-2WARMZ-RL uses the standard 8-lead MSOP (RM-8) pinout defined in Figure 4 and Table 7 of the Rev. G datasheet. It shares identical pin functions and spacing with non-automotive ADA4096-2ARMZ-RL and ADA4096-2BRMZ-RL, though only the "W" suffix denotes AEC-Q100 qualification and enhanced test screening.

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

No - the ADA4096-2WARMZ-RL is unity-gain stable per the General Description and Electrical Specifications. Its phase margin is 60° at ±15 V (Table 4), and closed-loop bandwidth remains stable at 1520 kHz with AV = 1. No external compensation components are needed for standard non-inverting or inverting configurations.

What is the thermal performance of the ADA4096-2WARMZ-RL in its MSOP package?

The ADA4096-2WARMZ-RL in 8-lead MSOP (RM-8) has θJA = 142°C/W and θJC = 45°C/W when mounted on a 4-layer JEDEC-standard PCB with zero airflow and the exposed pad soldered to V−. This allows continuous operation at up to +125°C ambient when dissipating ≤120 mW, matching automotive under-hood thermal requirements.

Can the ADA4096-2WARMZ-RL drive a 2 kΩ load while maintaining rail-to-rail output swing?

Yes - at ±15 V supply, the ADA4096-2WARMZ-RL delivers VOH ≥14.0 V and VOL ≤−14.75 V into a 2 kΩ load (Table 4), representing ≤1.0 V total headroom. At ±5 V, it achieves VOH ≥4.70 V and VOL ≤−4.75 V into 2 kΩ, confirming full rail-to-rail capability even under moderate loads.
