MAX934CSE-T belongs to the Linear - Comparators family. The device is an advanced precision low-power single/dual rail-to-rail comparator with an open-drain output, ±2.5mV(max) offset, and an operating supply voltage of 1.8V-5.5V. It is fully specified over an extended temperature range of -40°C to +125°C.

The MAX934CSE-T is intended for wide range of applications in analog signal processing, automotive, industrial and consumer markets. It is ideal for applications such as sensors, switches, digital potentiometers, trip-point monitoring, CCD line-sync, over/undervoltage protection, ring-tone detection, zero-crossing detection and ASIC post-layout verification.

This device features an open-drain output with no pull-up required, allowing simplified interface to external logic. It features programmable hysteresis to reduce noise sensitivity, as well as high-output sink capability of 24mA. It also features low input bias current and low offset voltage, high common-mode rejection, low input voltage noise, wide bandwidth and fast settling time.

The MAX934CSE-T functions by comparing two input voltages. The output switches from the high state to the low state whenever the positive input is greater than the negative input. The hysteresis of the comparator is set by 2 external resistors. This provides hysteresis for applications with large noise and removes the need for external debouncing.

The MAX934CSE compares the difference between two input signals and outputs HIGH or LOW depending on which is higher. A voltage range from 1.8V to 5.5V can be used to power the device, with a supply current of 350uA(max). The input voltage range is 0.3V below the supply rail to VCC. The offset voltage of the comparator is 2.5mV(max).

In summary, the MAX934CSE-T is designed to improve functionality and flexibility in comparator applications. It provide precision performance in a wide variety of applications, including analog signal processing, automotive, consumer, industrial and ASIC post-layout verification. Its features include a low-power design, adjustable hysteresis, programmable output strength, a wide voltage range, low offset voltage, high common-mode rejection and fast response time.
