Product details
Overview
ADA4098-2HCPZ from Analog Devices is a dual-channel, precision, Over-The-Top™ operational amplifier designed for high-voltage industrial sensing and monitoring. It operates from 3 V to 50 V supply, delivers 1.05 MHz gain bandwidth, draws only 165 µA per channel, and supports rail-to-rail input/output with common-mode range extending to −VS − 0.1 V up to −VS + 70 V - enabling direct battery or bus voltage sensing in harsh environments.
For engineers reviewing the ADA4098-2HCPZ datasheet, ADA4098-2HCPZ pinout, ADA4098-2HCPZ application, or ADA4098-2HCPZ equivalent, this page provides verified specifications, H-grade temperature performance (−55°C to +150°C), shutdown functionality, Over-The-Top™ input robustness, and real-world use cases in current sensing and power supply monitoring.
Technical Context
The ADA4098-2HCPZ implements an Over-The-Top™ input stage that maintains precision operation even when inputs exceed the negative rail by up to 70 V - critical for ground-referenced current sensing in high-side configurations. Its input stage tolerates ±80 V differential voltage without damage or dc accuracy degradation.
This dual op amp features independent shutdown pins (SHDN1/SHDN2) per channel, enabling selective power gating in multi-channel systems. It is unity-gain stable, drives 20 mA loads, and supports capacitive loads up to 200 pF - simplifying interface design in sensor front-ends and transmitter circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 50 V - supports single-supply industrial rails and wide-range battery monitoring without level-shifting. |
| Gain Bandwidth Product | 1.05 MHz typical - enables stable closed-loop operation at gains ≥1 with bandwidth sufficient for 4–20 mA loop signals. |
| Input Offset Voltage (max) | ±35 µV - ensures sub-0.1% error in precision current sense amplifiers with 100 mΩ shunts. |
| Common-Mode Input Range | −VS − 0.1 V to −VS + 70 V - allows direct connection to high-side shunts or battery terminals referenced to system ground. |
| Supply Current per Channel | 165 µA typical - enables low-power operation in always-on monitoring systems with extended battery life. |
| Operating Temperature | −55°C to +150°C (H grade) - qualified for under-hood automotive, downhole, and industrial control applications. |
| ESD Robustness | ±3 kV HBM, ±1.25 kV FICDM - withstands handling and board-level transients in factory and field environments. |
Pinout & Package
The ADA4098-2HCPZ is packaged in a 10-lead lead-frame chip-scale package (LFCSP), thermally enhanced with an exposed pad connected to −VS. This package supports high-density PCB layouts and improved thermal dissipation in compact industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VOUT1 / VOUT2 | Amplifier output terminals - rail-to-rail capable, drive up to 20 mA, high-impedance in shutdown mode. |
| 2, 8 | −IN1 / −IN2 | Inverting inputs - support Over-The-Top™ operation; tolerate >70 V above −VS without phase reversal. |
| 3, 7 | +IN1 / +IN2 | Noninverting inputs - matched bias current (<700 pA), enable precision differential and current-sense topologies. |
| 4 | −VS | Negative supply rail - must be connected to low-impedance ground plane; EPAD tied to this pin for thermal conduction. |
| 5, 6 | SHDN1 / SHDN2 | Independent channel shutdown controls - active-high logic (threshold = −VS + 1.5 V); reduce supply current to ≤20 µA per channel. |
| 10 | +VS | Positive supply rail - bypass with ≥0.1 µF capacitor near pin to suppress high-frequency noise and ensure stability. |
| EPAD | Exposed Thermal Pad | Internally connected to −VS - requires solder mask-defined thermal via array to internal ground plane for θJA = 43°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Over-The-Top™ Input Stage | Enables direct sensing of voltages up to 70 V above negative rail - eliminates need for external level shifters in high-side current monitoring. |
| Robust Input Protection | Tolerates ±80 V differential input voltage without damage or dc accuracy loss - critical for fault-tolerant industrial interfaces. |
| Low 1/f Noise Corner | 6 Hz typical - preserves signal integrity in low-frequency sensor conditioning (e.g., strain gauges, RTDs) without high-pass filtering. |
| Channel Separation | 115 dB at 1 kHz - prevents crosstalk between channels in dual-sensor or dual-loop applications such as redundant power monitors. |
| Shutdown Current | ≤20 µA per channel - enables dynamic power management in battery-powered data loggers or wake-on-event systems. |

| 4–20 mA Transmitter Front-End | Abusive Environment Sensor Conditioning |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6015IMS8#PBF | Wider supply range (4.5 V to 50 V), higher GBP (1.3 MHz), but no Over-The-Top™ input - requires external level shifting for >−VS + 5 V inputs. | Not suitable for direct high-side shunt sensing; limited to mid-rail common-mode ranges unless augmented with external circuitry. | Choose when higher bandwidth is required and input common-mode stays within rail limits. |
| OPA2189IDR | Zero-drift architecture (0.005 µV/°C), lower noise (7.2 nV/√Hz), but narrower supply (4.5 V to 36 V) and no Over-The-Top™ capability. | Cannot tolerate inputs >+VS or <−VS; unsuitable for battery-terminal or bus-monitoring applications with large common-mode excursions. | Prefer for ultra-low-drift, low-noise applications where common-mode voltage remains constrained. |
Compared with LT6015IMS8#PBF and OPA2189IDR, the ADA4098-2HCPZ uniquely combines Over-The-Top™ input operation, H-grade temperature range, and low quiescent current - making it the only option among the three qualified for unattenuated high-side current sensing in extended-temperature industrial systems.

FAQ
What is the maximum common-mode input voltage for ADA4098-2HCPZ?
The ADA4098-2HCPZ supports a guaranteed common-mode input range from −VS − 0.1 V to −VS + 70 V. This Over-The-Top™ capability allows the device to accurately condition signals referenced to system ground even when the input exceeds the negative supply rail by up to 70 V - a key requirement in high-side current sensing and battery monitoring applications where the ADA4098-2HCPZ is commonly deployed.
Does ADA4098-2HCPZ support shutdown mode, and how is it controlled?
Yes, the ADA4098-2HCPZ includes independent shutdown pins (SHDN1 and SHDN2) for each channel. An input voltage >−VS + 1.5 V places the corresponding amplifier into shutdown, reducing supply current to ≤20 µA per channel and placing the output in high-impedance state. The ADA4098-2HCPZ datasheet specifies 2.5 µs active-to-shutdown and 30 µs shutdown-to-active response times - enabling fast power cycling in energy-sensitive systems.
What package type is used for ADA4098-2HCPZ, and what are its thermal advantages?
The ADA4098-2HCPZ uses a 10-lead LFCSP (lead-frame chip-scale package) with an exposed thermal pad. When the EPAD is soldered to a −VS-connected PCB plane using thermal vias, the junction-to-ambient thermal resistance (θJA) is reduced to 43°C/W - significantly lower than SOIC_N (120°C/W) or MSOP (163°C/W) variants. This makes the ADA4098-2HCPZ ideal for compact, high-power-density industrial modules where thermal management is critical.
Can ADA4098-2HCPZ operate from a single 5 V supply while handling inputs above the positive rail?
No - the ADA4098-2HCPZ Over-The-Top™ architecture extends the input range only *above the negative rail* (up to −VS + 70 V), not above the positive rail. Inputs exceeding +VS may cause damage or undefined behavior. For inputs above +VS, external clamping or level-shifting is required. The ADA4098-2HCPZ is optimized for high-side sensing where the signal is referenced to ground and exceeds −VS - not for super-rail inputs relative to +VS.
What is the input offset voltage specification for ADA4098-2HCPZ over temperature?
The ADA4098-2HCPZ (H grade) guarantees a maximum input offset voltage of ±35 µV at 25°C and ±200 µV over the full −55°C to +150°C operating range. Its offset voltage drift is specified at ±0.8 µV/°C max - enabling high-accuracy, low-calibration industrial measurements. These values are validated per the ADA4098-2HCPZ datasheet Table 1 and apply to the 10-lead LFCSP variant under standard test conditions.
