Linear-Comparators

Linear-Comparators utilize operational amplifiers to provide a real-time function between two input signals and output a high or low logic level depending on the comparison result. Comparator circuits offer fast, single-pulse waveform sensing commonly used for quick and reliable event control in a variety of applications, such as those involving voltage-level detection and pulse-width modulation (PWM).

MAX9691EUA+T Application Field and Working Principle

The MAX9691EUA+T is a dual-channel, low-power and low-cost precision comparator ideal for use as an analog-to-digital converter or in waveform compairing applications. The device includes two comparators that provide open-drain outputs with a pull-up resistor (resistor from output to VDD) and a guaranteed supply current of only 1µA per channel.

Due to its high-accuracy performance, the MAX9691EUA+T is suitable for a variety of industrial, medical and automation applications. Its relatively low supply voltage range of 2.1 to 6V makes it an ideal choice for low voltage designs. Furthermore, the part features a wide common-mode input voltage range (−0.9V to VDD + 0.9V) and an error signal flag output, allowing it to easily interface with various logic voltage levels.

In terms of operation, the MAX9691EUA+T is designed to compare an input voltage at IN A over a known reference voltage at IN B and turn on the output (high) when the input exceeds the reference. In addition, the device includes a temperature-compensated internal hysteresis circuit for reliable operation independent of supply voltage and temperature. This hysteresis is adjustable via an external resistor connected between GND and the HYST pin.

Conclusion

The MAX9691EUA+T is an excellent choice for low cost and precise comparator applications with an industry-leading supply current per channel. Its adjustable hysteresis value, wide common-mode range, and low-power operation make it ideal for use as an analog-to-digital converter in industrial, medical, and automation applications.
