TLV7034PWR

Comparators Overview

The TLV7034PWR is a quad-channel analog comparator from the Texas Instruments TLV703x family, housed in a 14-pin TSSOP package. It operates on a supply voltage range of 1.6V to 6.5V with a typical quiescent current of 315nA per channel. The device features rail-to-rail inputs, push-pull outputs capable of sourcing 29mA and sinking 33mA, and an internal hysteresis of up to 25mV. Key electrical parameters include a propagation delay of 3µs, input offset voltage of ±8mV, and operation across a temperature range of -40°C to +125°C.

Comparators Feature Summary

• Rail-to-rail common-mode input voltage range extending beyond supply rails
• Push-pull output stage for direct drive capability without pull-up resistors
• Internal hysteresis to prevent output oscillation in noisy environments
• Power-on-reset circuitry ensures defined output state during power transitions

Comparators Applications

• Mobile phones and tablets
• Gas detectors and smoke/heat detectors
• Motion detectors
• Servo drive position sensors

Comparators Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-14 package variant when placing orders. Confirm that the application environment remains within the specified -40°C to +125°C operating temperature range. Ensure supply voltages do not exceed the absolute maximum ratings to maintain device reliability and avoid permanent damage.

Comparators Selection Notes

Select this component for designs requiring multiple comparators in a compact footprint with low power consumption. The push-pull output configuration simplifies interface requirements compared to open-drain alternatives. Consider the 3µs propagation delay for timing-sensitive applications and verify that the 315nA quiescent current aligns with system battery life targets.

Comparators Part Context

This part belongs to the TLV703x and TLV704x series of nano-power comparators. The TLV703x sub-series specifically utilizes push-pull outputs, whereas the TLV704x uses open-drain outputs. Both share similar electrical characteristics and are designed for space-critical portable and industrial applications.

Comparators FAQ

Does the TLV7034PWR have internal hysteresis?

Yes, the device includes internal hysteresis ranging from approximately 3mV to 25mV depending on the supply voltage and common-mode conditions.

What is the behavior of the output during power-on?

The internal power-on-reset (POR) circuit holds the output low at VEE while the supply voltage is below the minimum operating threshold.
