The ADCMP565BPZ is a high-speed, low-power precision CMOS differential-input comparator. It is an ideal solution in a variety of applications, such as motor control, process control, safety systems, and automotive electronics. This part belongs to the Linear-Comparators category. In this article, the application fields and working principle of the ADCMP565BPZ are explained.

Application Fields

The ADCMP565BPZ is suitable for a variety of applications such as motor control, process control, safety systems, and automotive electronics. It provides high-speed and low-power operation, as well as industry\'s lowest comparison latency of just 5ns. It has ultra-low propagation delay of only 10ns, and low offset and gain errors. This part has an input common mode range of -0.3V to +6.2V, and an output that is compatible with TTL and CMOS. This allows it to directly interface with digital logic.

Additionally, the ADCMP565BPZ has an ±25mV window comparator with programmable thresholds, a programmable hysteresis output that reduces false triggering and a single-wire serial control port that enables programmability of the thresholds, overdrive, hysteresis level, output drive, and power-down modes.

The ADCMP565BPZ is offered in 14-plastic small-outline packages and enables designer to reduce board spacing by 50% with the innovative TDFN package.

Working Principle

The ADCMP565BPZ is a precision CMOS differential-input comparator. It integrates a high-speed comparator and input buffers for improved accuracy and response time. The input section consists of a differential/common-mode amplifier followed by a voltage-follower amplifier. The amplifier provides both high input impedance to reduce loading of the signal source, and high common mode rejection ratio (CMRR) for improved accuracy and speed. The output driver is designed for low power dissipation, and low distortion to meet the clean-swing requirements of many applications.

The internal architecture of the ADCMP565BPZ includes a two-stage comparator, with the first stage performed by a high-impendance differential pair. The second stage uses a hysteresis feature that provides improved noise immunity. This internal hysteresis can be set with an external resistor, providing the designer with a simple, fast way to set the hysteresis level.

When the voltage difference exceeds the thresholds of the comparator, the output of the comparator switches from the low state to the high state, and back again when the voltage crosses one of the thresholds in the opposite direction. The ADCMP565BPZ is designed to work under a wide range of operating conditions, such as supply voltages from 2.7V to 5.5V and power-down supply current of less than 1µA.

Conclusion

The ADCMP565BPZ is a high performance CMOS differential input comparator operating on low power, suitable for motor control, process control, safety systems and automotive electronics. It provides high-speed and low-power operation, as well as ultra-low propagation delay, low offset and gain errors and industry\'s lowest comparison latency. The internal architecture of the ADCMP565BPZ includes a two-stage comparator and an output driver that enables low power dissipation and low distortion operation. This part is offered in 14-plastic small-outline packages and TDFN package.
