Overview
LT6015IS5#TRMPBF from Analog Devices (formerly Linear Technology) is a single-channel, rail-to-rail input/output precision operational amplifier featuring Over-The-Top® input architecture. It delivers ±50 µV max input offset voltage, 3.2 MHz gain bandwidth, 0.8 V/µs slew rate, and operates from 3 V to 50 V total supply with only 315 µA quiescent current per amplifier. It is designed for high-side current sensing in battery monitoring systems up to 76 V above ground.
For engineers reviewing the LT6015IS5#TRMPBF datasheet, LT6015IS5#TRMPBF pinout, LT6015IS5#TRMPBF application, or LT6015IS5#TRMPBF equivalent, this page provides verified technical context, package-specific pin functions, real-world application mappings, and validated alternative options for industrial power monitoring, 4–20 mA transmitters, and high-voltage data acquisition designs.
Technical Context
The LT6015IS5#TRMPBF implements an Over-The-Top® input stage enabling operation with inputs up to 76 V above V–, independent of V+, and includes internal protection against transient faults down to 25 V below V–. Its rail-to-rail output drives loads up to 25 mA and remains unity-gain stable with capacitive loads ≤ 200 pF.
It supports single-supply (3–50 V) and split-supply (±1.5 V to ±25 V) operation, features reverse battery protection to –50 V, and exhibits no phase reversal or supply sequencing issues. Input common-mode range spans V– to V– + 76 V, and CMRR/PSRR are both specified at 126 dB over temperature.
Key Specifications

| Gain Bandwidth Product | 3.2 MHz - Enables stable closed-loop operation up to ~300 kHz at unity gain with minimal phase margin degradation. |
| Slew Rate | 0.8 V/µs - Supports accurate reproduction of signals with <3.5 µs 0.1% settling time for ±2 V steps. |
| Input Offset Voltage | ±50 µV max (I-grade, –40°C to 85°C) - Enables sub-0.1% error in precision current shunt amplification at 100 mV full-scale. |
| Supply Current | 315 µA per amplifier - Allows continuous operation in always-on battery-powered instrumentation with multi-year runtime. |
| Common-Mode Input Range | V– to V– + 76 V - Permits direct high-side sensing in 48 V, 60 V, and telecom battery stacks without level-shifting circuitry. |
| CMRR / PSRR | 126 dB - Rejects >99.9997% of supply ripple and common-mode noise in noisy industrial power rails. |
| Operating Temperature | –40°C to +85°C - Qualified for commercial and extended-temperature industrial environments without derating. |
Pinout & Package
LT6015IS5#TRMPBF is housed in a 5-lead TSOT-23 (ThinSOT™) package with exposed pad connected to V– for thermal and electrical integrity. Pin 1 is OUT, Pin 2 is V–, Pin 3 is +IN, Pin 4 is –IN, Pin 5 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Amplifier output | Drives loads up to 25 mA; rail-to-rail swing enables full utilization of ADC input range in single-supply systems. |
| V– (Pin 2) | Negative supply / reference | Must be tied to system ground or negative rail; exposed pad must be soldered to PCB ground plane for thermal stability and noise immunity. |
| +IN (Pin 3) | Non-inverting input | Accepts voltages from V– to V– + 76 V; Over-The-Top architecture eliminates need for external level shifters in high-side sensing. |
| –IN (Pin 4) | Inverting input | Same Over-The-Top range as +IN; used for feedback in current-sense configurations where shunt is on high side of load. |
| V+ (Pin 5) | Positive supply | Accepts 3–50 V total supply; bypass capacitor (0.1 µF) required adjacent to pin for stability under dynamic load conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Over-The-Top® input stage | Enables direct connection to high-side shunts in 48 V–76 V battery systems without external biasing or level shifting. |
| Rail-to-rail I/O | Maximizes dynamic range in low-voltage (e.g., 5 V) microcontroller-based data acquisition systems. |
| Reverse battery protection | Draws <5 µA at –50 V reverse supply - prevents latch-up and damage during field-replaceable battery insertion errors. |
| No phase reversal | Eliminates output polarity inversion during input overdrive - critical for closed-loop control stability in motor drivers and power supplies. |
| Low 0.75 µV/°C offset drift | Ensures <±15 µV offset variation across –40°C to +85°C - maintains calibration integrity in unheated outdoor equipment. |
Applications
| High-Side Current Monitoring | Battery Voltage Supervision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6015HS5#TRMPBF | Same die, extended temperature grade (–40°C to 125°C); identical electrical specs except wider VOS drift tolerance. | Required for under-hood automotive or high-ambient industrial enclosures where junction temperatures exceed 85°C. | Select when operating ambient exceeds 85°C and long-term offset stability at elevated temperature is critical. |
| AD8628ARJZ-R7 | Zero-drift chopper amplifier; 1 µV max VOS, but limited CMIR to V– to V+ – 1.2 V and no Over-The-Top capability. | Not suitable for high-side sensing >5 V; best for low-voltage, ultra-low-offset applications like strain gauge bridges. | Choose only for sub-1 µV offset requirements in low-voltage (<12 V), low-CMIR systems where Over-The-Top is unnecessary. |
Compared with LT6015HS5#TRMPBF, the LT6015IS5#TRMPBF trades extended temperature operation for lower cost and qualification scope; compared with AD8628ARJZ-R7, it sacrifices ultra-low offset for robust high-CMIR performance essential in battery and power rail monitoring.

FAQ
What is the maximum input common-mode voltage for LT6015IS5#TRMPBF?
The LT6015IS5#TRMPBF supports an input common-mode range from V– to V– + 76 V. This means its inputs can operate up to 76 V above the negative supply rail - a key enabler for high-side current sensing in 48 V and 60 V battery systems without external level-shifting components. This specification is guaranteed across the full –40°C to +85°C operating temperature range.
Does LT6015IS5#TRMPBF require external compensation for stability?
No, the LT6015IS5#TRMPBF is unity-gain stable and does not require external compensation under standard conditions. It maintains stability with capacitive loads up to 200 pF. For loads exceeding 200 pF, optional external compensation (e.g., series resistor at output) may be added per the datasheet Figure 12 guidance - but this is not needed for typical 4–20 mA transmitter or battery monitor implementations.
Can LT6015IS5#TRMPBF be used in reverse-battery fault conditions?
Yes, the LT6015IS5#TRMPBF includes integrated reverse-battery protection rated to –50 V. During such faults, supply current drops to <5 µA per amplifier, preventing damage and allowing safe recovery upon correction. This feature is especially valuable in field-deployed battery-powered equipment where incorrect battery installation is a known risk.
What is the typical supply current of LT6015IS5#TRMPBF at 5 V supply?
The LT6015IS5#TRMPBF draws 315 µA per amplifier at 5 V supply, as specified in the Electrical Characteristics table (I-grade, TA = 25°C). This value remains stable across the full –40°C to +85°C range, varying by less than ±10% - making it ideal for always-on, low-power instrumentation where energy budget is constrained.
Is LT6015IS5#TRMPBF pin-compatible with other packages in the LT6015/LT6016/LT6017 family?
No, LT6015IS5#TRMPBF uses the 5-lead TSOT-23 (S5) package and is not pin-compatible with the 8-lead MSOP (LT6016) or 22-lead DFN (LT6017) variants. Each variant has distinct pin counts, layouts, and thermal pads. Migration requires PCB redesign; however, electrical behavior and functional specifications are consistent across the family for equivalent channels.
