Product details
Overview
LT6015IS5#TRPBF 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 ±50µV max input offset voltage, 3.2MHz gain bandwidth, 0.8V/µs slew rate, and operates from 3V to 50V total supply with only 315µA quiescent current per amplifier. It is optimized for high-side current sensing in battery monitoring and 4mA–20mA transmitter circuits.
For engineers reviewing the LT6015IS5#TRPBF datasheet, LT6015IS5#TRPBF pinout, LT6015IS5#TRPBF application, or LT6015IS5#TRPBF equivalent, key selection criteria include its 76V input common-mode range above V–, reverse battery protection to 50V, –40°C to 85°C temperature grade, SOT-23-5 package, and guaranteed performance on single 5V or split ±15V supplies.
Technical Context
The LT6015IS5#TRPBF implements an Over-The-Top® input stage enabling operation with inputs up to 76V above V–-independent of V+-making it suitable for direct high-voltage node interfacing without level-shifting. Its input stage includes internal resistors that protect against transients down to 25V below V–.
It features unity-gain stability with capacitive loads up to 200pF and supports optional external compensation for enhanced capacitive drive capability. The amplifier maintains rail-to-rail output swing (within 55mV of rails at 5mA load) and exhibits no phase reversal or supply sequencing issues.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3.2MHz - Enables stable closed-loop operation up to ~300kHz at gain = 10, supporting precision signal conditioning in data acquisition. |
| Input Offset Voltage (max) | ±50µV - Ensures <0.1% error in mV-level differential measurements, critical for shunt-based current sensing. |
| Supply Current per Amp | 315µA - Allows battery-powered operation for >10 years on a typical CR2032 cell in low-duty-cycle monitoring systems. |
| Input Common-Mode Range | V– to V– + 76V - Permits direct connection to high-side bus voltages up to 76V above ground, eliminating need for external attenuators. |
| CMRR / PSRR | 126dB - Rejects >2 million-to-1 common-mode or supply noise, essential for accurate measurement in noisy industrial environments. |

Pinout & Package
LT6015IS5#TRPBF is housed in a 5-lead TSOT-23 (ThinSOT™) package, measuring 2.9mm × 1.6mm × 0.8mm, with exposed pad thermally connected to V– for improved thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ≥25mA; requires local 0.1µF bypass if driving heavy or capacitive loads. |
| 2 (V–) | Negative supply | Reference for all inputs and outputs; exposed pad must be soldered to PCB ground plane or low-impedance V– trace for thermal and noise integrity. |
| 3 (+IN) | Non-inverting input | Accepts signals from V– to V– + 76V; high common-mode rejection enables direct high-side sensing without attenuation. |
| 4 (–IN) | Inverting input | Matches +IN in Over-The-Top® range and bias behavior; used with +IN for differential or single-ended configurations. |
| 5 (V+) | Positive supply | Accepts up to +60V relative to V–; reverse-battery protected to –50V; requires local 0.1µF ceramic bypass capacitor. |
Key Features

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#TRPBF | Same electrical specs but rated for –40°C to +125°C junction temperature; higher max VOS (±55µV) at extended temp. | Suitable for under-hood automotive or high-temp industrial enclosures where ambient exceeds 85°C. | Select when operating ambient exceeds 85°C and extended temperature validation is required; same footprint and biasing. |
| AD8628ARJZ-R7 | Zero-drift architecture; lower VOS (±10µV typ), but limited input common-mode range (to V+ – 1.2V); no Over-The-Top® capability. | Preferred for ultra-low-offset DC-coupled sensors at low voltages (<5V), but cannot replace LT6015IS5#TRPBF in high-side sensing. | Choose only for low-voltage, low-drift applications where 76V common-mode range is unnecessary; not a functional substitute in high-side roles. |
Compared with LT6015HS5#TRPBF, the LT6015IS5#TRPBF trades extended temperature rating for tighter initial VOS spec and lower cost; versus AD8628ARJZ-R7, it sacrifices zero-drift performance for unique high-common-mode-range functionality essential in power rail monitoring.

FAQ
What is the maximum input common-mode voltage for LT6015IS5#TRPBF?
The LT6015IS5#TRPBF supports an input common-mode voltage range from V– to V– + 76V. This Over-The-Top® capability allows the device to operate with inputs 76V above the negative supply rail-regardless of V+-enabling direct high-side sensing without level shifters. This specification is guaranteed over the full –40°C to +85°C temperature range and applies to both input pins.
Does LT6015IS5#TRPBF require external compensation for stability?
No, the LT6015IS5#TRPBF is unity-gain stable and does not require external compensation for capacitive loads up to 200pF. Its internal compensation ensures stable operation in standard gain configurations (e.g., G = +1, –1, +10). External compensation is optional only when driving larger capacitive loads (>200pF) or when optimizing for specific phase margin requirements in custom designs.
Can LT6015IS5#TRPBF be used with a single 3.3V supply?
Yes, the LT6015IS5#TRPBF operates with a minimum total supply voltage of 3V, making it compatible with single 3.3V (V+ = 3.3V, V– = 0V) configurations. In this setup, its rail-to-rail input and output stages allow full utilization of the 0V–3.3V range, and its 315µA supply current supports ultra-low-power applications. Performance parameters-including VOS, GBW, and CMRR-are specified down to 3V total supply.
What is the reverse battery protection rating of LT6015IS5#TRPBF?
The LT6015IS5#TRPBF provides reverse battery protection up to –50V on the V+ pin relative to V–, drawing less than 5µA supply current under that condition. This feature eliminates the need for external blocking diodes in battery-powered equipment, improving efficiency and reliability in applications like portable test gear and backup power systems where polarity reversal is a risk.
Is LT6015IS5#TRPBF pin-compatible with other members of the LT6015/LT6016/LT6017 family?
Yes, the LT6015IS5#TRPBF shares identical pinout (OUT, V–, +IN, –IN, V+) and footprint with all other LT6015 variants in the SOT-23-5 package (e.g., LT6015HS5#TRPBF, LT6015MPS5#TRPBF). However, it is not pin-compatible with the dual LT6016 (MSOP-8) or quad LT6017 (DFN-22), which use different packages and pin counts. Board designs using LT6015IS5#TRPBF can be upgraded to higher temperature grades without layout changes.
