Product details
Overview
LT6016HMS8#PBF from Analog Devices (formerly Linear Technology) is a dual precision rail-to-rail input/output operational amplifier featuring Over-The-Top® input architecture, ±50µV max input offset voltage, 3.2MHz gain bandwidth product, and operation from 3V to 50V total supply. It delivers high-side current sensing capability with 76V common-mode input range above V–, enabling direct monitoring of battery or high-voltage bus voltages in automotive and industrial power systems.
For engineers reviewing the LT6016HMS8#PBF datasheet, LT6016HMS8#PBF pinout, LT6016HMS8#PBF application, or LT6016HMS8#PBF equivalent, this device is selected for high-accuracy signal conditioning where input common-mode voltage exceeds the positive rail - especially in 4mA–20mA transmitters, high-voltage data acquisition, and reverse-battery-protected power supply monitoring circuits.
Technical Context
The LT6016HMS8#PBF implements an Over-The-Top® input stage that extends the common-mode range to V– + 76V independent of V+, supported by internal fault-protection resistors rated for transients down to 25V below V–. Its input stage operates without phase reversal across the full common-mode range and eliminates supply sequencing constraints.
This dual op amp achieves unity-gain stability driving capacitive loads up to 200pF and supports optional external compensation for enhanced capacitive drive. It draws only 315µA per amplifier at 5V supply and maintains specified performance over –40°C to +125°C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±50 µV max (guaranteed over –40°C to +125°C), enabling sub-0.1% error in precision current sensing at 100mV sense voltage. |
| Common-Mode Input Range | V– to V– + 76V (independent of V+), allowing direct connection to high-side shunts in 24V/48V/60V battery systems without level-shifting. |
| Gain Bandwidth Product | 3.2 MHz (typical), supporting closed-loop bandwidths >300 kHz in gain-of-10 configurations for fast transient response in feedback loops. |
| Supply Current per Amplifier | 315 µA (typical at 5V), enabling low-power operation in always-on battery-monitoring circuits with <1 mW per channel. |
| CMRR / PSRR | 126 dB (min), rejecting noise from shared power rails and common-mode disturbances in noisy industrial environments. |
| Operating Temperature | –40°C to +125°C (H-grade), qualified for under-hood automotive and industrial control applications without derating. |
| Reverse Battery Protection | Withstands –50V reverse supply while drawing <5 µA, eliminating need for external series diodes in vehicle battery interfaces. |
Pinout & Package
LT6016HMS8#PBF is housed in an 8-lead plastic MSOP (MS8) package with exposed pad connected to V– for thermal and electrical integrity. Pin pitch is 0.65 mm; body dimensions are 3.0 mm × 3.0 mm × 1.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Amplifier A output | Capable of sourcing/sinking 25 mA; rail-to-rail swing within 500 mV of rails at 5 mA load. |
| 2 (–INA) | Inverting input of Amp A | Part of Over-The-Top® differential pair; withstands –25V to +80V relative to V–. |
| 3 (+INA) | Non-inverting input of Amp A | Same Over-The-Top® rating as –INA; enables high-side sensing with VCM = VBAT > V+. |
| 4 (V–) | Negative supply terminal | Must be connected to system ground or negative rail; exposed pad must be soldered to PCB ground plane. |
| 5 (V+) | Positive supply terminal | Accepts 3V to 50V total supply; bypass with 0.1 µF ceramic capacitor placed adjacent to pin. |
| 6 (OUTB) | Amplifier B output | Independent output; identical drive capability and swing specs as OUTA. |
| 7 (–INB) | Inverting input of Amp B | Electrically isolated from Amp A inputs; shares same Over-The-Top® protection and voltage ratings. |
| 8 (+INB) | Non-inverting input of Amp B | Enables dual-channel high-side monitoring (e.g., battery + load current) in single package. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Guaranteed operation without output polarity inversion across full VCM range (V– to V– + 76V), critical for stable closed-loop control. |
| Rail-to-rail I/O | Input accepts signals from V– to V+, output swings within 500 mV of either rail at 5 mA load - maximizes dynamic range in low-voltage systems. |
| Over-The-Top® input stage | Enables direct connection to high-side shunts without external level shifters or charge pumps, reducing BOM count and layout complexity. |
| Low long-term drift | 0.75 µV/°C offset drift and 0.75 µV/month long-term stability ensure calibration longevity in unattended instrumentation. |
| High voltage gain | 1000 V/mV open-loop gain ensures <0.01% gain error in precision amplification stages with moderate closed-loop gains. |
Applications
| High-Side Current Sensing | Battery Voltage Monitoring |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision high-voltage op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6016IMS8#PBF | Same silicon, but rated for –40°C to +85°C ambient (I-grade vs H-grade); 315µA IS spec applies only at 25°C, not over full temp range. | Suitable for commercial-grade industrial controllers without under-hood or outdoor thermal exposure. | Select when ambient temperature remains ≤85°C and cost sensitivity outweighs extended temperature qualification. |
| ADA4522-2ARZ | Zero-drift architecture; 0.3µV max VOS, 0.005µV/°C drift, but limited VCMR to V– to V+ + 0.3V - no Over-The-Top® capability. | Preferred for ultra-low-drift DC-coupled instrumentation where input voltage stays within supply rails. | Choose only if common-mode voltage never exceeds V+, and sub-µV offset stability is prioritized over high-side sensing. |
Compared with LT6016IMS8#PBF, the LT6016HMS8#PBF guarantees ±50µV VOS and 315µA IS over –40°C to +125°C, making it suitable for automotive engine compartments; versus ADA4522-2ARZ, it trades zero-drift performance for 76V Over-The-Top® input range - a non-substitutable feature in high-side current sensing.

FAQ
What is the maximum common-mode input voltage for LT6016HMS8#PBF?
The LT6016HMS8#PBF supports a common-mode input range from V– to V– + 76V, independent of the V+ supply voltage. This Over-The-Top® capability allows direct connection to high-side shunts in 48V or 60V battery systems without level-shifting circuitry. Absolute maximum input voltage is +80V relative to V–, with fault protection up to –25V relative to V–.
Does LT6016HMS8#PBF require external compensation for stability?
No, the LT6016HMS8#PBF is unity-gain stable and drives capacitive loads up to 200pF without external compensation. For loads exceeding 200pF (e.g., long cables or ADC input capacitance), optional external compensation via a series RC network from output to inverting input can extend stability margin - details are provided in the Applications Information section of the LT6015/LT6016/LT6017 datasheet.
Can LT6016HMS8#PBF operate with a single 5V supply?
Yes, the LT6016HMS8#PBF operates from a total supply voltage of 3V to 50V, including single 5V (V+ = 5V, V– = 0V) or split ±2.5V configurations. At 5V supply, it delivers rail-to-rail input and output swing, 3.2MHz GBW, and 315µA per amplifier quiescent current - making it ideal for portable instrumentation and low-power industrial sensors.
What is the reverse battery protection rating of LT6016HMS8#PBF?
The LT6016HMS8#PBF is rated for reverse battery protection up to –50V on the V+ pin (with V– grounded), drawing less than 5µA supply current during fault conditions. This eliminates the need for external series diodes or MOSFET-based protection in automotive and off-grid power systems, simplifying design and improving efficiency.
How does the Over-The-Top® input stage improve reliability in LT6016HMS8#PBF?
The Over-The-Top® input stage in the LT6016HMS8#PBF uses specialized PNP transistor structures that remain functional even when input voltages exceed V+, preventing latch-up, phase reversal, or parametric degradation. Internal 1kΩ series resistors protect against transients down to –25V relative to V–, enabling robust operation in electrically noisy environments like motor drives and battery chargers.
