Product details
Overview
LT6700IS6-1#TRPBF from Analog Devices is a micropower dual comparator with integrated 400mV reference, designed for low-voltage system monitoring in industrial and automotive applications. It features one noninverting input (INA) and one inverting input (INB), open-collector outputs capable of sinking >5mA, 6.5µA quiescent current at 5V, and operates from 1.4V to 18V supply. Used in battery voltage supervision and window detection circuits where precision thresholding and low power are critical.
For engineers reviewing the LT6700IS6-1#TRPBF datasheet, LT6700IS6-1#TRPBF pinout, LT6700IS6-1#TRPBF application, or LT6700IS6-1#TRPBF equivalent, key selection factors include its ±1.25% max total threshold error at 25°C, internal hysteresis (6.5mV typ), –40°C to 85°C industrial temperature rating, SOT-23-6 package, and compatibility with over-the-top inputs referenced to ground or up to 36V.
Technical Context
The LT6700IS6-1#TRPBF implements two independent comparators sharing a single precision 400mV internal reference. Comparator A accepts external signals on its noninverting input (+INA), while Comparator B uses its inverting input (–INB); both second inputs are internally tied to the reference. This configuration enables direct window comparator implementation without external resistors.
Its open-collector outputs support level translation - OUTA/OUTB can be pulled up to voltages as high as 18V (independent of VS), enabling interface with higher-voltage logic or relay drivers. Input common-mode range extends from GND to 18V (36V for HV variants), and internal hysteresis eliminates need for external feedback networks in noisy environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4V to 18V - supports operation directly from single-cell Li-ion or alkaline batteries and standard industrial rails. |
| Quiescent Current | 6.5µA typ at 5V - enables multi-year battery life in always-on monitoring systems. |
| Reference Accuracy | ±1.25% max total threshold error at 25°C - ensures reliable trip-point consistency across production units. |
| Hysteresis | 6.5mV typ - suppresses output oscillation due to noise near threshold without external components. |
| Input Bias Current | ±10nA max - minimizes loading error on high-impedance sensor or divider networks. |
| Output Sink Current | >5mA guaranteed over temperature - drives LEDs, small relays, or logic gates directly. |
| Operating Temp Range | –40°C to +85°C - qualified for industrial control and automotive cabin electronics. |
Pinout & Package
LT6700IS6-1#TRPBF is housed in a 6-lead plastic TSOT-23 (S6) package, 2.9mm × 1.6mm × 1.0mm profile, with exposed pad thermally connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA | Open-collector output of Comparator A | Sinks current when +INA exceeds 400mV; pull-up required; supports up to 18V off-state voltage. |
| GND | Ground reference and reference low terminal | Common return for supply, reference, and outputs; must be low-impedance for stable threshold accuracy. |
| +INA | Noninverting input of Comparator A | Accepts input from 0V to 18V (or 36V for HV versions); used with internal 400mV reference for high-side detection. |
| OUTB | Open-collector output of Comparator B | Sinks current when –INB falls below 400mV; independently controllable; same voltage tolerance as OUTA. |
| VS | Core supply voltage input | Powers internal comparators and reference; decoupling capacitor recommended close to pin. |
| –INB | Inverting input of Comparator B | Accepts input from 0V to 18V; used with internal 400mV reference for low-side or window boundary detection. |
Key Features
| Feature | Design Value |
|---|---|
| Dual comparator + 400mV reference | Eliminates external reference IC and resistor dividers, reducing BOM count and layout area in threshold-detection designs. |
| Over-the-top input capability | Enables direct sensing of signals above VS (up to 36V), supporting high-side battery or bus voltage monitoring without level-shifting circuitry. |
| Internal hysteresis | 6.5mV typical hysteresis prevents chatter in noisy environments - no external feedback resistors needed for stability. |
| Open-collector outputs | Allow flexible interfacing: outputs can be pulled to any voltage ≤18V (36V HV), enabling mixed-voltage system integration. |
| Low input bias current | ±10nA max ensures minimal error in high-impedance voltage divider networks used for scaling input signals. |
Applications
| Battery Voltage Monitor | Window Comparator |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator with reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6700IS6-2#TRPBF | Two inverting inputs (–INA, –INB) instead of mixed polarity; identical specs otherwise. | Requires inverted signal routing or external inversion for high-threshold detection; better suited for dual-low-side monitoring. | Select LT6700IS6-2#TRPBF only when both thresholds require inverting configuration - not a drop-in replacement for LT6700IS6-1#TRPBF. |
| TLV3701IDBVR | Single comparator with 1.24V reference, no internal hysteresis, 1.8V–16V supply, 1.2µA IQ. | Lacks dual-channel integration and fixed 400mV reference; requires external hysteresis and resistor scaling for window function. | Choose TLV3701IDBVR only for ultra-low-power single-threshold applications where board area allows added passives and reference. |
Compared with LT6700IS6-1#TRPBF, LT6700IS6-2#TRPBF offers identical performance but reversed input polarity - requiring schematic changes - while TLV3701IDBVR trades integration and hysteresis for lower quiescent current and higher reference voltage, increasing design complexity for window detection.

FAQ
What is the reference voltage accuracy of the LT6700IS6-1#TRPBF over temperature?
The LT6700IS6-1#TRPBF features a total threshold error of ±1.25% maximum at 25°C. Over the full –40°C to +85°C industrial temperature range, the rising input threshold voltage varies by approximately ±2mV (±0.5%) around 400mV, as confirmed by typical performance curves in the datasheet. This stability is achieved through matched internal resistor and reference design.
Can the LT6700IS6-1#TRPBF operate from a 1.4V supply and still drive a 5mA load?
Yes. The LT6700IS6-1#TRPBF is fully specified down to 1.4V supply and guarantees >5mA sink capability over temperature. At VS = 1.4V and IOUT = 0.5mA, VOL is 200mV max; at VS = 5V and IOUT = 5mA, VOL remains ≤200mV. Its output stage is designed for robust low-voltage operation without performance degradation.
Is the LT6700IS6-1#TRPBF pin-compatible with other LT6700 variants like LT6700IS6-2#TRPBF?
No. While LT6700IS6-1#TRPBF and LT6700IS6-2#TRPBF share identical pinout and package (SOT-23-6), their input polarities differ: LT6700IS6-1#TRPBF has +INA and –INB, whereas LT6700IS6-2#TRPBF has –INA and –INB. Swapping them requires signal routing changes and may invert logic behavior - they are functional alternatives, not pin-compatible replacements.
Does the LT6700IS6-1#TRPBF require external hysteresis components?
No. The LT6700IS6-1#TRPBF integrates 6.5mV typical hysteresis per comparator, eliminating the need for external positive-feedback resistors. This internal hysteresis is factory-trimmed and stable over temperature and supply voltage, simplifying design and improving repeatability in threshold-detection applications.
What is the maximum input voltage the LT6700IS6-1#TRPBF can tolerate on +INA or –INB pins?
The LT6700IS6-1#TRPBF supports input voltages from GND – 0.3V to 18V on +INA and –INB, independent of VS. This "over-the-top" capability allows direct monitoring of signals referenced to higher potentials - e.g., battery voltage or 12V bus - without level shifters or clamping diodes, provided current into the pin is limited per Absolute Maximum Ratings.
