Product details
Overview
LT6700IS6-1#TRMPBF 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 typical supply current at 5V, and operates from 1.4V to 18V supply.
For engineers reviewing the LT6700IS6-1#TRMPBF datasheet, LT6700IS6-1#TRMPBF pinout, LT6700IS6-1#TRMPBF application, or LT6700IS6-1#TRMPBF equivalent, this part supports precision threshold detection with ±1.25% max total threshold error at 25°C, internal hysteresis (6.5mV typ), and over-the-top inputs operating to 36V - critical for battery voltage supervision and window comparator designs.
Technical Context
The LT6700IS6-1#TRMPBF integrates two independent comparators sharing a precision 400mV internal reference; each comparator has one externally accessible input while the other connects internally to the reference. Its input architecture supports over-the-top operation down to ground, enabling direct sensing of signals referenced to GND or above VS.
Both outputs are open-collector with rail-to-rail sink capability up to 18V (independent of VS), allowing level translation across domains. The device includes built-in hysteresis (6.5mV typ) to prevent oscillation near thresholds, eliminating external feedback components in most monitoring applications.
Key Specifications

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#TRMPBF | Two inverting inputs instead of one noninverting + one inverting; identical specs otherwise. | Requires inverted signal routing or external inversion for same window function; less intuitive for asymmetric thresholds. | Select only if existing PCB layout or signal polarity favors dual inverting configuration. |
| TLV3701IDBVR | Single comparator with 1.24V reference; no internal hysteresis; 850nA IQ; SOT-23-6 package. | Lacks dual-channel integration and fixed 400mV reference; requires external hysteresis and scaling for window detection. | Use when ultra-low IQ (<1µA) is mandatory and single-threshold detection suffices. |
Compared with LT6700IS6-1#TRMPBF, LT6700IS6-2#TRMPBF offers identical performance but different input polarity - limiting direct substitution without layout changes - while TLV3701IDBVR trades integration and hysteresis for extreme low-power operation, increasing design complexity for dual-threshold tasks.

FAQ
What is the reference voltage tolerance of the LT6700IS6-1#TRMPBF over temperature?
The LT6700IS6-1#TRMPBF features a total threshold error of ±1.25% maximum at 25°C, with typical rising threshold variation of ±2mV over –40°C to +85°C. This combines reference drift and comparator offset, ensuring predictable trip points across its full rated temperature range without external trimming.
Can the LT6700IS6-1#TRMPBF operate from a 1.4V supply while driving a 5mA load?
Yes - the LT6700IS6-1#TRMPBF is fully specified down to 1.4V supply and guarantees >5mA sink capability per output over temperature. At 1.4V, VOL is 200mV max at 5mA, leaving sufficient headroom for standard logic or LED drive in ultra-low-voltage systems.
How does the input polarity of the LT6700IS6-1#TRMPBF differ from LT6700IS6-2#TRMPBF?
The LT6700IS6-1#TRMPBF has +INA (noninverting) and –INB (inverting), enabling direct window comparator implementation with one input above and one below the 400mV reference. In contrast, LT6700IS6-2#TRMPBF has –INA and –INB, requiring both external signals to be inverted relative to the reference for equivalent functionality.
Is the LT6700IS6-1#TRMPBF pin-compatible with the LT6700HVIS6-1#TRMPBF?
No - while both share the same SOT-23-6 package and pinout, the LT6700HVIS6-1#TRMPBF supports higher absolute maximum input/output voltages (up to 36V vs. 18V) and has different electrical specifications (e.g., higher supply current). They are not drop-in replacements without verifying voltage margin and thermal design.
Does the LT6700IS6-1#TRMPBF require external hysteresis resistors?
No - the LT6700IS6-1#TRMPBF includes internal hysteresis of 6.5mV typical, eliminating the need for external positive feedback resistors. This simplifies design for basic threshold detection and reduces board space, though external hysteresis can be added if larger hysteresis is required.
