Application Fields and Working Principle

The LMV7239M7X/NOPB has found many applications in professional audio equipment, such as pre-amplifiers, studio monitors, loudspeakers and sound systems. It is highly suitable for applications where a low-noise, reliable and accurate comparison of audio signals is required. In its simplest form, the LMV7239M7X/NOPB consists of two inputs, a pair of comparator circuits, and an output. The two inputs are referred to as VINH and VINL, which accept signals with a voltage differential (VINH to VINL) of up to 6V. This differential specifies the input voltage range of the LMV7239M7X/NOPB.

When an analog input is applied to VINH or VINL, a pair of comparator circuits will be triggered. The output of the comparator circuit that is triggered first will be latched, and the result will be transmitted to the open-drain output, OUT. If the voltage differential of VINH and VINL is greater than 6V, the output will remain in its latched state and the comparator circuit will not toggle until the voltage differential is reduced below 6V. If VINH and VINL are both low, the comparator circuit will remain in the low output state.

Complementary outputs are available in the LMV7239M7X/NOPB to accommodate dual rail power supplies. The COMP pin indicates the complement of the OUT pin, and can be used to drive loads that require signals with opposite polarity. The propagation delay of the LMV7239M7X/NOPB typically ranges from 20ns to 140ns, making it well-suited for applications where fast response and low latency are of utmost importance.

Conclusion

The LMV7239M7X/NOPB is a high performance, low-noise, open-drain comparator specifically designed for use in professional audio equipment. It is well-suited for audio processing applications that require a reliable and accurate comparison of signals with a differential of up to 6V. Additionally, the LMV7239M7X/NOPB features a host of features such as EMI-hardened architecture, low power consumption, and fast response time, making it an ideal choice for those looking for a reliable, high performance comparator.
