Product details
Overview
LT6700MPS6-1#TRMPBF from Analog Devices is a micropower dual comparator with integrated 400mV reference, designed for low-voltage system monitoring in harsh environments. It features one noninverting input (INA) and one inverting input (INB), open-collector outputs rated to 18V, 6.5µA typical supply current at 5V, ±10nA max input bias current, and operates across –55°C to 125°C.
For engineers reviewing the LT6700MPS6-1#TRMPBF datasheet, LT6700MPS6-1#TRMPBF pinout, LT6700MPS6-1#TRMPBF application, or LT6700MPS6-1#TRMPBF equivalent, this part supports precision threshold detection, battery voltage supervision, window comparator configurations, and industrial control systems requiring extended temperature reliability and rail-to-rail input capability.
Technical Context
The LT6700MPS6-1#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 Over-The-Top® input architecture enables operation with inputs up to 36V above ground, independent of supply voltage.
Both outputs are open-collector with guaranteed sinking capability >5mA over temperature and output voltage tolerance up to 18V. Internal hysteresis (6.5mV typ) eliminates external components for stable switching, and the device supports supply voltages from 1.4V to 18V - enabling use in single-cell Li-ion, multi-cell alkaline, and industrial 12V/24V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4V to 18V - supports single-cell battery operation and standard industrial rails without level-shifting. |
| Quiescent Current | 6.5µA typ at 5V - enables multi-year battery life in always-on monitoring applications. |
| Reference Accuracy | ±1.25% max total threshold error at 25°C - ensures reliable trip-point consistency across voltage and temperature. |
| Input Bias Current | ±10nA max - minimizes loading on high-impedance sensor or divider networks. |

Pinout & Package
Package: 6-lead plastic TSOT-23 (S6), 1mm profile, RoHS-compliant, tape-and-reel (500 pcs).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA | Open-collector output of Comparator A | Sinks current up to 5mA; off-state voltage tolerates up to 18V regardless of VS - enables level translation to higher-voltage logic or loads. |
| GND | Ground reference and reference low terminal | Common return for internal 400mV reference and comparator core; must be connected to system ground for accurate thresholding. |
| +INA | Noninverting input of Comparator A | Accepts input from –0.3V to 18V vs GND; used with internal 400mV reference to detect rising thresholds (e.g., battery OK). |
| OUTB | Open-collector output of Comparator B | Independent sink output; supports dual-threshold or window-comparator top/bottom detection. |
| VS | Comparator core supply voltage | Powers internal circuitry only; does not supply outputs - allows output loads referenced to separate rails. |
| –INB | Inverting input of Comparator B | Accepts input from –0.3V to 18V vs GND; compares against same 400mV reference to detect falling thresholds (e.g., battery low warning). |
Key Features
