Product details
Overview
LTC6702CTS8#TRMPBF from Analog Devices (formerly Linear Technology) is a dual micropower rail-to-rail comparator in an 8-lead TSOT-23 package, operating from 1.7V to 5.5V supply, delivering 500ns max propagation delay with only 30μA/comparator quiescent current and 4mV internal hysteresis-used in battery-powered threshold detection and clock regeneration circuits.
For engineers reviewing the LTC6702CTS8#TRMPBF datasheet, LTC6702CTS8#TRMPBF pinout, LTC6702CTS8#TRMPBF application, or LTC6702CTS8#TRMPBF equivalent, key selection criteria include guaranteed –40°C to 85°C operation, CMOS-compatible push-pull outputs, input range extending 100mV below ground, and compatibility with high-impedance sensor interfaces in space-constrained portable systems.
Technical Context
The LTC6702CTS8#TRMPBF integrates two independent comparators with built-in 4mV hysteresis per channel, eliminating external feedback components for noise-immune threshold detection. Its CMOS input stage supports source impedances up to 10MΩ while maintaining sub-500ns propagation delay across the full temperature range.
Each comparator features rail-to-rail push-pull output capable of sourcing/sinking ±15mA, specified down to 1.7V supply, with output swing within 250mV of GND and 350mV of V+ at full load-enabling direct interfacing with TTL/CMOS logic without pull-up resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.7V to 5.5V - enables operation from single-cell Li-ion (3.0V), coin cell (3V), or 5V logic rails without level shifting. |
| Quiescent Current | 30μA per comparator max - supports multi-year battery life in always-on sensing nodes. |
| Propagation Delay | 500ns max over –40°C to 85°C - ensures reliable timing-critical decisions in clock recovery up to 3.2MHz. |
| Input Hysteresis | 4mV typical - suppresses chatter on slow-moving or noisy analog signals without external components. |
| Input Voltage Range | –0.1V to V+ – 1.2V - allows direct interface with transducers biased below ground or above rail. |
| Output Drive | ±15mA at –40°C to 85°C - drives 10kΩ loads directly and handles capacitive loads up to 10,000pF. |
| Operating Temperature | –40°C to 85°C - qualified for industrial and automotive cabin applications. |

Applications
| Battery-Powered Threshold Detection | Window Comparator for Sensor Monitoring |
|---|---|
Use Scenario: Detecting low-battery condition in portable medical devices using a precision voltage divider off a Li-ion cell. IC Role / Device Role / Timing Role: Dual comparator compares battery voltage against upper and lower thresholds to assert "OK" and "LOW" flags. Use Value: 30μA total quiescent current extends device runtime; internal hysteresis prevents false triggers during transient load dips. | Use Scenario: Monitoring temperature sensor output in HVAC control to trigger alarm if reading falls outside safe band. IC Role / Device Role / Timing Role: One comparator detects upper limit, the other lower limit; outputs combined via wired-OR logic. Use Value: 4mV hysteresis rejects EMI-induced noise on long sensor traces; rail-to-rail outputs interface directly with MCU GPIOs. |

Use Scenario: Recovering clean clock edges from degraded or attenuated system clocks in data acquisition modules. IC Role / Device Role / Timing Role: Comparator A conditions rising edge, Comparator B falling edge; outputs combined to reconstruct square wave. Use Value: 500ns max delay and 3.2MHz toggle frequency support precise timing recovery in 1–3MHz serial links. | Use Scenario: Monitoring motor phase currents in BLDC drives to disable PWM if overcurrent occurs. IC Role / Device Role / Timing Role: Compares amplified shunt voltage against dual thresholds to generate fast trip signals for gate drivers. Use Value: Input range extending below GND accommodates bidirectional current sensing; 500ns response enables sub-microsecond fault shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6700IMS8#TRPBF | Integrated 400mV reference; higher 18μs propagation delay; 1.4V–18V supply range. | Eliminates external reference but trades speed for wide-supply flexibility - suited for high-voltage industrial monitoring. | Select when reference integration outweighs speed requirement and supply exceeds 5.5V. |
| LTC1442CMS8#TRPBF | Ultralow 5.7μA quiescent current; open-drain outputs; no internal hysteresis; 8μs delay. | Optimized for extreme battery life over speed; requires external hysteresis and pull-ups - ideal for infrequent wake-up sensing. | Select when nanowatt operation is mandatory and response time >10μs is acceptable. |

FAQ
What is the maximum operating temperature range for the LTC6702CTS8#TRMPBF?
The LTC6702CTS8#TRMPBF is specified for operation from –40°C to 85°C. This grade ('I' suffix) is qualified across that full industrial temperature range, with all electrical parameters guaranteed per the datasheet under those conditions. It is not rated for the –40°C to 125°C range like the 'H' grade variants.
Does the LTC6702CTS8#TRMPBF require external hysteresis for stable operation?
No, the LTC6702CTS8#TRMPBF includes 4mV of internal hysteresis per comparator, which is sufficient to prevent oscillation due to input noise or slow signal transitions. External hysteresis is optional and only needed when greater hysteresis magnitude is required for specific noise margins.
Can the LTC6702CTS8#TRMPBF operate from a 1.8V supply?
Yes, the LTC6702CTS8#TRMPBF operates from 1.7V to 5.5V, so 1.8V is fully supported. At 1.8V, it maintains 500ns max propagation delay and 30μA/comparator max supply current, with output swing within 250mV of GND and 350mV of V+ at ±15mA load - verified over temperature.
What is the input voltage range relative to ground for the LTC6702CTS8#TRMPBF?
The LTC6702CTS8#TRMPBF accepts input voltages from –0.1V (100mV below ground) up to V+ – 1.2V. This allows direct connection to transducers or amplifiers whose outputs swing slightly negative or near the positive rail, without clamping diodes or level-shifting circuitry.
Is a bypass capacitor required on the V+ pin of the LTC6702CTS8#TRMPBF?
Yes, a minimum 0.1μF ceramic capacitor is required between V+ and GND, placed as close as possible to the device pins. When sourcing or sinking ≥1mA, a 1μF capacitor is recommended to maintain stability and minimize supply-induced propagation delay variation.
