Product details
Overview
LT1716CS5#TRPBF from Analog Devices is a micropower, precision rail-to-rail comparator with Over-the-Top® input stage enabling operation with inputs up to 44V above V–, independent of V+. It draws only 35µA quiescent current, achieves 1.5mV max input offset voltage, and delivers rail-to-rail output swing (within 35mV of V– and 55mV of V+). It is widely used in lamp monitors, power supply supervisors, and relay drivers requiring high common-mode tolerance and low-power single-supply operation.
For engineers reviewing the LT1716CS5#TRPBF datasheet, LT1716CS5#TRPBF pinout, LT1716CS5#TRPBF application, or LT1716CS5#TRPBF equivalent, key selection criteria include its 44V over-the-top input capability, 35µA supply current, –40°C to 85°C temperature grade, SOT-23-5 package, and internal pull-up current source eliminating external resistors.
Technical Context
The LT1716CS5#TRPBF employs a three-stage input architecture (NPN/PNP/common-base) enabling seamless operation across wide common-mode ranges-from 0.5V above V– to 44V above V–-and tolerating inputs up to 5V below V– without phase reversal. Its unique input stage uses built-in 5kΩ protection resistors and Schottky clamping to withstand faults while maintaining valid output logic.
The output stage integrates a class-B pull-up current source (≈60–85µA typical), enabling direct drive of loads referenced to supplies higher than V+, functionally equivalent to an open-collector output but with lower power consumption and no external pull-up required. Propagation delay is 3–5.5µs with 100mV overdrive into 10kΩ load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 44V total - supports wide-input industrial and automotive power rails without external regulation. |
| Quiescent Current | 35µA max at 25°C - enables always-on monitoring in battery-powered or energy-sensitive systems. |
| Input Offset Voltage | 1.5mV max over –40°C to 85°C - ensures accurate threshold detection in precision sensing applications. |
| Input Common-Mode Range | Extends 44V above V–, independent of V+ - allows direct interface to high-side signals without level-shifting. |
| Output Swing | Within 35mV of V– and 55mV of V+ - delivers true rail-to-rail logic compatibility for low-voltage microcontrollers. |
| Propagation Delay | 3µs typical (100mV overdrive, 10kΩ load) - provides fast response for timing-critical fault detection and oscillator circuits. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and commercial environments, not automotive-grade (H-grade required). |
Pinout & Package
LT1716CS5#TRPBF is housed in a 5-lead TSOT-23 (S5) package - ultra-thin (1mm height), surface-mount, JEDEC MO-193 compliant, with 0.95mm pitch and 2.80mm × 1.90mm footprint. Pin 1 is marked by a dot; top-view orientation places OUT at Pin 1, V– at Pin 2, +IN at Pin 3, V+ at Pin 4, and –IN at Pin 5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Open-drain–like output with internal pull-up | Drives high/low actively; sinks current to V–, sources ≈60–85µA to V+; compatible with loads up to 44V above V–. |
| 2 (V–) | Negative supply reference | Ground or negative rail reference; all input/output voltages referenced to this node; inputs tolerate –5V relative to V–. |
| 3 (+IN) | Noninverting input | High-impedance input accepting 0.5V to 44V above V–; bias current varies with common-mode region (nA to µA range). |
| 4 (V+) | Positive supply | Power rail (2.7V–44V); removal shuts down device, reducing input bias current to <3nA even with overvoltage inputs. |
| 5 (–IN) | Inverting input | High-impedance input with identical voltage range and protection as +IN; internal 5kΩ resistor limits fault current to ≤1mA at –5V below V–. |
Key Features
| Feature | Design Value |
|---|---|
| Over-the-Top® Input Stage | Enables direct sensing of signals up to 44V above V– regardless of V+ value - eliminates need for external level shifters in high-side monitoring. |
| Internal Pull-Up Current Source | ≈60–85µA class-B source replaces external pull-up resistor - reduces BOM count, saves board space, and cuts standby power in open-drain configurations. |
| Rail-to-Rail Output Swing | Swings within 35mV of V– and 55mV of V+ - ensures reliable logic-level interfacing with 3.3V or 5V MCUs without external level translation. |
| Input Fault Tolerance | Withstands –5V below V– on either input with no phase reversal - built-in 5kΩ resistors limit fault current to ≤1mA, enhancing system robustness. |
| Micropower Operation | 35µA max supply current over full temperature range - enables continuous supervision in energy-constrained applications like remote sensors or backup systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1719CS5#TRPBF | Faster propagation delay (4.5ns vs 3µs), higher supply current (1.2mA), no over-the-top input - requires level shifting for high-side sensing. | Better suited for high-speed digital interface or clock generation; unsuitable for direct 44V-above-V– sensing. | Select LT1719CS5#TRPBF only when speed >1MHz is required and input common-mode stays within rail limits. |
| TLV3701DBVR | Lower IQ (1µA), rail-to-rail input/output, but max supply 16V and input CMR limited to V– to V+ - no over-the-top capability. | Ideal for ultra-low-power battery monitoring below 16V; cannot replace LT1716CS5#TRPBF in 24V/48V industrial sensing. | Choose TLV3701DBVR for sub-16V, nanowatt applications where over-the-top operation is unnecessary. |
Compared with LT1716CS5#TRPBF, LT1719CS5#TRPBF trades micropower and over-the-top input for nanosecond speed, while TLV3701DBVR offers extreme low power but sacrifices voltage range and fault tolerance - making LT1716CS5#TRPBF uniquely balanced for industrial high-voltage, low-power threshold detection.

FAQ
What is the maximum input voltage the LT1716CS5#TRPBF can tolerate relative to V–?
The LT1716CS5#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– without output phase reversal, thanks to internal 5kΩ protection resistors that limit fault current to ≤1mA. This makes LT1716CS5#TRPBF ideal for high-side sensing in unregulated or variable-voltage systems.
Does the LT1716CS5#TRPBF require an external pull-up resistor on its output?
No, the LT1716CS5#TRPBF features an integrated class-B pull-up current source (60–85µA typical) that eliminates the need for an external pull-up resistor. This design reduces component count, saves PCB area, and lowers system power consumption - especially beneficial in battery-operated or space-constrained applications where LT1716CS5#TRPBF is deployed.

The LT1716CS5#TRPBF is rated for operation from –40°C to +85°C, corresponding to the "C" grade variant per Analog Devices' ordering nomenclature. This specification is fully guaranteed and tested across the range, distinguishing it from the automotive-grade LT1716HS5#TRPBF (–40°C to +125°C) and ensuring reliability in industrial and commercial environments where LT1716CS5#TRPBF is commonly applied.
Can the LT1716CS5#TRPBF drive a load referenced to a voltage higher than its own V+ supply?
Yes, the LT1716CS5#TRPBF output stage is designed to drive loads connected to supplies up to 44V above V– - even when that supply exceeds the LT1716CS5#TRPBF's own V+ rail. This behavior mirrors open-collector outputs and enables direct interfacing with higher-voltage logic or relay coils without additional level-shifting circuitry, a key advantage in multi-rail industrial systems using LT1716CS5#TRPBF.
What is the typical input offset voltage and drift of the LT1716CS5#TRPBF?
The LT1716CS5#TRPBF has a maximum input offset voltage of 1.5mV over its full –40°C to +85°C operating range, with typical value of 300µV at 25°C. Its offset voltage drift is specified at 2µV/°C over temperature - ensuring stable threshold accuracy in thermally varying environments where LT1716CS5#TRPBF performs precision monitoring tasks such as power supply fault detection or battery voltage windowing.
