TLV3691IDPFR

Comparators Overview

The TLV3691IDPFR is a single-channel analog comparator from Texas Instruments, housed in a 5-pin SC-70 package. It operates within a supply voltage range of 0.9 V to 6.5 V and supports an industrial temperature range from -40°C to 125°C. The device features rail-to-rail inputs that extend 100 mV beyond the supply rails and a push-pull output stage. Key electrical specifications include a maximum quiescent current of 150 nA at 25°C, a typical input offset voltage of ±3 mV, and a propagation delay of 24 µs.

Comparators Feature Summary

• Rail-to-rail input stage capable of operating up to 100 mV beyond both power supply rails without phase inversion.
• Push-pull output stage eliminates the need for external pull-up resistors while maintaining nano-power operation.
• Internal hysteresis reduces sensitivity to noise in signal processing applications.

Comparators Applications

• Overvoltage and undervoltage detection circuits
• Window comparators for voltage monitoring
• Zero-crossing detection systems
• Smart phones and portable medical devices

Comparators Procurement Notes

Verify the specific ordering suffix 'IDPFR' against the manufacturer's official documentation to confirm the SC-70 package type and reel quantity. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision date with your design timeline to account for any potential specification updates or changes.

Comparators Selection Notes

Select this component when designing low-voltage portable electronics requiring minimal power consumption. The wide supply range and extended common-mode input range provide flexibility for interfacing with various sensors. The compact SC-70 package is suitable for space-constrained PCB layouts where standard packages cannot fit.

Comparators Part Context

This part belongs to the TLV3691 family of nanopower comparators designed by Texas Instruments. The family includes variants in different packages such as DFN-6 and SC-70. These devices are engineered for battery-operated applications where low standby current and high accuracy are critical performance factors.

Comparators Replacement Considerations

Consult the manufacturer's cross-reference tools for verified substitutes. Ensure any replacement maintains the same supply voltage range, package dimensions, and electrical characteristics like quiescent current and offset voltage.

Comparators FAQ

Does the TLV3691 exhibit phase inversion when input voltages exceed the supply rails?

No, the device is designed to prevent phase inversion even when input signals swing beyond the positive or negative supply rails.

What is the purpose of the internal hysteresis in this comparator?

The internal hysteresis helps reduce the comparator's sensitivity to noise, allowing for stable operation in noisy environments without requiring additional external components.
