The MAX934CPE is a single, low-power, open-drain output comparator that is designed for use in a wide variety of applications. The MAX934CPE is a 55x41x19mm plastic moulded ceramic package, which allows for greater flexibility in application from industry to consumer electronics applications.

The MAX934CPE features a linear-to-comparator input structure, which translates the linear signal into a digital returned result. The input voltage is converted to a 12-bit digital data word depending on the reference voltage. This data is sent to the SOP-8 compatible output port and is read out by the MAX934CPE for its required action. The MAX934CPE is ideal for applications where a digital result is required from a linear signal, including ADC, DAC, oscillators and frequency synthesizers.

The MAX934CPE comprises two main blocks, the linear-to-comparator input structure and the output logic block. The linear-to-comparator input structure provides a 0.06V to 15V input voltage range and a 12-bit data word generation with less than 0.2% linearity error. This structure also guarantees a fast settling time of 10µs when the input voltage is changed.

The output logic block performs the logic analysis of the 12-bit data word read by the MAX934CPE and sets the status of the output port accordingly. The outputs can be open-drain or pull-up/pull-down type and are individually programmable to operate from 0V to 15V. The PIN control lines further enable customization of the output port.

The MAX934CPE provides a wide supply voltage range from 2.5V to 4.2V and is thus ideal for battery powered applications. It also contains inbuilt ESD protection that exceeds the requirements of the industry standard. The power consumption of the MAX934CPE is very low at around 0.4mW.

The MAX934CPE is suitable for a wide range of applications such as automotive, high performance audio, instrumentation amplifiers, comparator and ADC systems. It is also ideal for line receivers, temperature control, motor speed control and high-resolution analogue-to-digital converters. The linear-to-comparator input structure and the 12-bit data word offers increased accuracy and speed in comparison to other comparator solutions available on the market today.
