Product details
Overview
LT1716IS5#TRPBF from Analog Devices is a micropower, precision rail-to-rail comparator with Over-the-Top® input capability, operating from 2.7V to 44V supply and drawing only 35µA quiescent current. Its inputs withstand 44V above V– (independent of V+), output swings within 35mV of V– and 55mV of V+, and it features internal pull-up current sourcing - enabling direct drive of loads referenced to higher supplies. It is used in lamp monitors, power supply supervisors, and relay drivers where wide common-mode range and low power are critical.
For engineers reviewing the LT1716IS5#TRPBF datasheet, LT1716IS5#TRPBF pinout, LT1716IS5#TRPBF application, or LT1716IS5#TRPBF equivalent, key selection considerations include its –40°C to 85°C temperature grade, SOT-23-5 package, 1.5mV max offset voltage, 5.5µs propagation delay, and ability to maintain valid output when either input is driven 5V below V–.
Technical Context
The LT1716IS5#TRPBF employs a three-stage input architecture (NPN/PNP/common-base) enabling operation across an extended common-mode range - from 0.5V above V– to 44V above V–, including regions beyond V+. This architecture supports fault-tolerant behavior: one input may remain within spec while the other drops up to 5V below V– without phase reversal.
Its output stage integrates a class-B pull-up current source (≈60–85µA typical), eliminating external pull-up resistors and reducing power consumption. The output can sink ≥10mA and swing rail-to-rail - to within 35mV of V– and 55mV of V+ - while driving loads referenced to voltages up to 44V above V–, matching open-collector functionality without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 44V total - supports single-supply industrial and automotive systems without level-shifting. |
| Input Common-Mode Range | Extends 44V above V–, independent of V+ - enables direct sensing of high-side signals (e.g., battery, bus) without attenuators. |
| Quiescent Current | 35µA max at 25°C - enables always-on monitoring in battery-powered or energy-constrained applications. |
| Input Offset Voltage | 1.5mV max over –40°C to 85°C - ensures accurate threshold detection in precision supervisory circuits. |
| Propagation Delay | 5.5µs typical (100mV overdrive, RL = 10kΩ) - suitable for medium-speed control loops and fault flag generation. |
| Output Swing | Within 35mV of V– and 55mV of V+ - delivers full logic-level compatibility with 3.3V/5V microcontrollers even at low supply voltages. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and commercial environments; not AEC-Q100 automotive-grade (H-grade required). |

| 2 - V– | Negative supply rail | Reference node for input common-mode and output swing; inputs tolerate 5V below this pin without invalid output. |
| 3 - +IN | Noninverting input | Differential input terminal with bias current <35nA typical; operates from 0.5V to 44V above V–, including >V+. |
| 4 - V+ | Positive supply rail | Power supply connection; device shuts down when removed; reverse-battery protected up to 20V. |
| 5 - –IN | Inverting input | Differential input terminal symmetric to +IN; same Over-the-Top® range and fault tolerance; internal 5kΩ series resistor limits fault current. |
Key Features
| Feature | Design Value |
|---|---|
| Over-the-Top® Input Stage | Enables direct high-side sensing - e.g., monitoring 48V bus with 3.3V supply - without external resistive dividers or level shifters. |
| Internal Pull-Up Current Source | Eliminates external pull-up resistor, saving board space and reducing standby power - especially valuable in portable or remote sensors. |
| Rail-to-Rail Output Swing | Ensures clean logic transitions into 3.3V/5V MCU GPIOs or optocouplers, even at minimum 2.7V supply, improving noise margin. |
| Valid Output with Input Below V– | Guarantees correct comparator decision when one input is pulled 5V below V– - critical for ground-referenced fault detection in negative-rail systems. |
| Low Input Bias Current Variation | Bias current remains ≤100nA across full common-mode range (–14.5V to +44V relative to V–), minimizing offset errors in high-impedance sensor interfaces. |
Applications
| Lamp Monitor | Power Supply Supervisor |
|---|---|
|
Use Scenario: Detecting open-circuit or short-circuit conditions in automotive or industrial lighting circuits powered from 12V–48V rails. IC Role / Device Role: Comparator compares sensed current through shunt resistor against reference; drives LED driver enable or fault flag. Use Value: Over-the-Top® inputs allow direct sensing on high-side of lamp load without isolation; 35µA IQ enables always-on diagnostics. |
Use Scenario: Monitoring DC output of switching or linear regulators (e.g., 3.3V, 5V, 12V) for undervoltage/overvoltage faults. IC Role / Device Role: Compares regulated output against precision reference; asserts reset or interrupt signal upon deviation. Use Value: 1.5mV max offset ensures tight trip accuracy; rail-to-rail output interfaces directly with µC reset pins or FPGA I/O. |
| Relay Driver Control | Oscillator / Window Detector |
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC1442CMS8#PBF | Dual comparator + integrated 1.182V reference; ±10mV max offset; 12µA IQ; SO-8 package. | Requires external reference routing; better for dual-threshold or reference-sharing designs; larger footprint. | Choose LTC1442 when dual comparators and built-in reference simplify BOM and layout - but not for single-channel Over-the-Top® sensing. |
| LT1634BCS8-1.25#PBF | Precision shunt reference (1.25V, 0.05% initial accuracy, 10ppm/°C drift); not a comparator. | Provides stable reference voltage only; must pair with separate comparator (e.g., LT1716) for supervision. | Use LT1634 with LT1716IS5#TRPBF when highest accuracy reference is required - e.g., for programmable trip points in test equipment. |
Compared with LTC1442CMS8#PBF, LT1716IS5#TRPBF offers superior input voltage range and single-channel optimization; compared with LT1634BCS8-1.25#PBF, it provides active decision-making rather than passive voltage regulation - making LT1716IS5#TRPBF the sole solution for direct high-side sensing and fault-flag generation.

FAQ
What is the maximum input voltage the LT1716IS5#TRPBF can tolerate relative to V–?
The LT1716IS5#TRPBF supports an input common-mode voltage range extending up to 44V above V–, independent of the V+ supply voltage. It also tolerates inputs as low as 5V below V– while maintaining valid output - enabled by internal 5kΩ series resistors and robust input stage design. This makes LT1716IS5#TRPBF ideal for high-side sensing in 48V systems with low-voltage logic supplies.
Does the LT1716IS5#TRPBF require an external pull-up resistor on its output?
No, the LT1716IS5#TRPBF integrates a class-B pull-up current source (~60–85µA typical), eliminating the need for an external pull-up resistor. This reduces component count, saves PCB area, and lowers system power - especially beneficial in battery-powered or space-constrained designs. The output can still be pulled up externally if higher drive strength or different logic levels are required.
What is the operating temperature range specified for the LT1716IS5#TRPBF?
The LT1716IS5#TRPBF is rated for operation from –40°C to +85°C, corresponding to the "I" grade per Analog Devices' ordering nomenclature. This range is fully tested and guaranteed - unlike the "C" grade (0°C to 70°C) or "H" grade (–40°C to 125°C). It is not AEC-Q100 qualified; automotive use requires the LT1716HS5#WTRPBF variant.
Can the LT1716IS5#TRPBF drive a load referenced to a voltage higher than its own V+ supply?
Yes - the LT1716IS5#TRPBF output stage is designed to drive loads connected to supplies up to 44V above V–, regardless of the LT1716IS5#TRPBF's own V+ voltage. This open-collector–equivalent behavior enables level shifting and interfacing with higher-voltage peripherals (e.g., 24V PLC inputs) without additional level translators or isolation.
What is the typical propagation delay of the LT1716IS5#TRPBF under standard conditions?
The LT1716IS5#TRPBF exhibits a typical propagation delay of 5.5µs when driven with ≥100mV overdrive into a 10kΩ load, measured at 25°C. Delay increases slightly at temperature extremes and with lower overdrive - e.g., ~9µs at 125°C or with 10mV overdrive. This performance suits medium-speed supervision, oscillator, and fault-detection applications.
