Key Features
- Automotive AEC-Q100 qualified quad comparator for reliable -40°C to 125°C operation in harsh environments
- Ultra-low 30pA (0.00003µA) maximum bias current minimizes loading on high-impedance sensor inputs
- Push-pull output stage enables direct logic-level interfacing without external pull-up resistors
- Four independent comparator channels in 14-pin SOIC reduce component count in multi-channel threshold detection designs
Applications
The TLC3704QDRQ1 is designed for automotive body electronics, powertrain control modules, and battery management systems requiring accurate multi-channel voltage threshold detection. Its ultra-low input bias current makes it ideal for interfacing with high-impedance capacitive or resistive sensors in ADAS, lighting control, and smart motor management applications. Industrial designers also use it in over-voltage and under-voltage detection circuits, window comparator networks, and oscillator circuits where low bias current and push-pull outputs simplify system design.

Frequently Asked Questions
What are the key electrical specifications of the TLC3704QDRQ1?
The TLC3704QDRQ1 is a quad CMOS comparator with push-pull outputs, featuring a maximum input offset voltage of 5mV (5000µV), an extremely low maximum input bias current of 30pA (0.00003µA), and four independent comparator channels in a 14-pin SOIC package. It is AEC-Q100 automotive qualified and Pb-free (JESD-609 e4).
Why is the ultra-low bias current of the TLC3704QDRQ1 important?
The 30pA maximum input bias current is critical when interfacing with high-impedance signal sources such as capacitive sensors, piezoelectric transducers, or resistive voltage dividers. Such low bias current prevents measurement errors due to excessive loading on the source, making the TLC3704QDRQ1 suitable for precision threshold detection in sensitive sensor circuits.
What is the output type of the TLC3704QDRQ1 and how does it simplify design?
The TLC3704QDRQ1 features push-pull outputs, which can both source and sink current directly to drive logic inputs or small loads without requiring an external pull-up resistor. This differs from open-drain comparators and reduces BOM cost and PCB space in automotive and industrial comparator applications where multiple channels are used.
What applications is the TLC3704QDRQ1 suited for in automotive and industrial designs?
This quad comparator is suited for automotive voltage monitoring, window comparator circuits, over-voltage and under-voltage protection, LED driver control, battery cell balancing threshold detection, and motor control signal conditioning. Its AEC-Q100 qualification and 14-pin SOIC package make it a reliable choice for under-hood and cabin automotive electronic systems.
