Product details
Overview
LT1716IS5#TRMPBF from Analog Devices is a micropower, precision rail-to-rail comparator in a 5-lead TSOT-23 package, operating from 2.7V to 44V with 35µA quiescent current, ±1.5mV max input offset voltage, and Over-the-Top® input stage enabling common-mode operation up to 44V above V–-ideal for high-side lamp monitoring and power supply fault detection in industrial and automotive systems.
For engineers reviewing the LT1716IS5#TRMPBF datasheet, LT1716IS5#TRMPBF pinout, LT1716IS5#TRMPBF application, or LT1716IS5#TRMPBF equivalent, this page delivers verified electrical specs, temperature-rated performance (–40°C to 85°C), rail-to-rail output swing (35mV from V–, 55mV from V+), internal pull-up current source, and fault-tolerant input design for reliable overvoltage and reverse-battery scenarios.
Technical Context
The LT1716IS5#TRMPBF uses a three-stage input architecture (NPN/PNP/common-base) enabling seamless operation across three distinct input voltage regions: below V–, within rails, and >44V above V–-with no phase reversal even when one input is forced 5V below V–. Its output stage integrates a class-B pull-up current source, eliminating external pull-up resistors while supporting loads referenced to supplies higher than its own V+.
Input protection includes built-in 5kΩ series resistors and Schottky clamping, allowing safe operation with inputs up to 5V below V– or 44V above V– under differential or common-mode stress. The device meets AEC-Q100 requirements for automotive use and supports single- or split-supply configurations without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 44V total - enables direct interface with 12V/24V/48V industrial and automotive bus voltages without level-shifting. |
| Quiescent Current | 35µA typical at 5V - supports always-on monitoring in battery-backed or energy-constrained systems. |
| Input Offset Voltage | ≤1.5mV max (–40°C to 85°C) - ensures accurate threshold detection in precision voltage supervision applications. |
| Input Common-Mode Range | Extends 44V above V–, independent of V+ - allows high-side sensing without external attenuators or isolated supplies. |
| Output Swing | Within 35mV of V– and 55mV of V+ - delivers robust logic-level compatibility with 3.3V/5V microcontrollers in single-supply designs. |
| Propagation Delay | 3µs typical (100mV overdrive, 10kΩ load) - provides fast response for overcurrent flagging and relay control timing-critical paths. |
| Operating Temperature | –40°C to +85°C - qualified for extended industrial and commercial environments, excluding automotive-grade H-temp variants. |
Pinout & Package
LT1716IS5#TRMPBF is housed in a low-profile 5-lead TSOT-23 (S5) package (1.0mm max height), optimized for space-constrained PCB layouts and automated assembly. Pin 1 is marked with a dot; the package conforms to JEDEC MO-193 and features 0.95mm pitch, 1.90mm body width, and 2.80mm length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Open-collector–like output | Class-B pull-up current source drives loads referenced to V+ or higher supplies; sinks up to 20mA; swings rail-to-rail. |
| 2 (V–) | Negative supply terminal | Reference node for input common-mode range and output swing; supports inputs down to –5V relative to this pin. |
| 3 (+IN) | Noninverting input | Differential input stage accepts voltages from –5V to 44V relative to V–; bias current varies by region (nA to µA). |
| 4 (V+) | Positive supply terminal | Power rail for internal circuitry; removal shuts down device with <3nA input bias current remaining. |
| 5 (–IN) | Inverting input | Matches +IN in voltage range and fault tolerance; internal 5kΩ resistor protects against –5V faults below V–. |
Key Features
| Feature | Design Value |
|---|---|
| Over-the-Top® Input Stage | Enables direct high-side sensing at 44V above V– without external components-critical for battery stack monitoring and 48V DC bus supervision. |
| Internal Pull-Up Current Source | Eliminates external pull-up resistor, reducing BOM count and board area while cutting standby power in always-on comparators. |
| Rail-to-Rail Output Swing | 35mV low / 55mV high swing ensures TTL/CMOS-compatible logic levels across full supply range-no level-shifter needed for MCU interfacing. |
| Input Fault Tolerance | Withstands –5V transients on either input (relative to V–) with no phase reversal or latch-up-supports robust field-deployed systems. |
| Micropower Operation | 35µA IQ at 5V enables multi-year battery life in remote sensors and portable diagnostic tools requiring continuous voltage monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1719IS5#TRMPBF | Faster propagation delay (4.5ns vs 3µs), higher supply current (1.3mA), same SOT-23-5 package and Over-the-Top® input. | Better suited for high-speed digital interface monitoring; not ideal for micropower battery applications. | Select LT1719IS5#TRMPBF only when speed >100kHz is required; LT1716IS5#TRMPBF remains optimal for sub-10kHz precision monitoring. |
| TLV3701IDBVR | Lower IQ (1µA), rail-to-rail I/O, but limited input range (V– to V+ +0.2V); no Over-the-Top® capability or –5V fault tolerance. | Only suitable for low-voltage, low-power applications where inputs stay within supply rails-cannot replace LT1716IS5#TRMPBF in high-side sensing. | Choose TLV3701IDBVR for ultra-low-power 3.3V systems; avoid where input exceeds V+ or drops below V–. |
Compared with LT1719IS5#TRMPBF and TLV3701IDBVR, the LT1716IS5#TRMPBF uniquely balances micropower operation (35µA), extreme input voltage tolerance (44V above V–), and fault resilience (–5V below V–), making it irreplaceable in high-reliability industrial power monitoring where both precision and ruggedness are mandatory.

FAQ
What is the maximum input voltage the LT1716IS5#TRMPBF can tolerate relative to V–?
The LT1716IS5#TRMPBF supports input voltages up to 44V above V– in both differential and common-mode configurations, and tolerates up to 5V below V– without phase reversal or damage-enabled by internal 5kΩ series resistors and Schottky clamping. This Over-the-Top® capability is confirmed in the Absolute Maximum Ratings and Applications Information sections of the official datasheet.
Does the LT1716IS5#TRMPBF require an external pull-up resistor on its output?
No, the LT1716IS5#TRMPBF integrates a class-B pull-up current source that actively drives the output high, eliminating the need for an external pull-up resistor. This reduces component count, saves board space, and lowers system power consumption-verified in the "Output" section of the Applications Information and Electrical Characteristics tables.
What is the guaranteed operating temperature range for the LT1716IS5#TRMPBF?
The LT1716IS5#TRMPBF is specified for operation from –40°C to +85°C, as indicated by the "I" grade suffix and confirmed in the Order Information table and Specified Temperature Range notes. This range covers extended industrial environments but excludes the automotive-grade "H" variant rated to 125°C.
Can the LT1716IS5#TRMPBF drive a load referenced to a voltage higher than its own V+ supply?
Yes-the LT1716IS5#TRMPBF output stage is explicitly designed to drive loads connected to supplies higher than V+, functioning like an open-collector output. The datasheet confirms it can be pulled up to 44V above V– regardless of V+, enabling direct interface with higher-voltage logic or optocouplers without level-shifting circuitry.
What is the typical input offset voltage drift over temperature for the LT1716IS5#TRMPBF?
The LT1716IS5#TRMPBF has a guaranteed input offset voltage drift of 2µV/°C over the full –40°C to +85°C range, as specified in the Electrical Characteristics table under "Input Offset Voltage Drift." This low drift ensures stable threshold accuracy across wide ambient temperature variations in industrial deployments.
