MAXIM INTEGRATED / ANALOG DEVICES MAX9034ASD quad comparator

The MAX9034ASD+ is a low-cost, quad comparator packaged in a 14-pin NSOIC. Designed for single supply operation from +2.5V to +5.5V, it can also function with dual supplies. The comparator offers a typical propagation delay of 188ns and consumes approximately 35µA of current per comparator. Its low power consumption and support for voltage levels down to +2.5V make it ideal for portable applications. The device features 4mV of built-in hysteresis, which provides noise immunity and prevents oscillations even with slow input signals. The input common mode voltage range extends from the negative supply to within 1.1V of the positive supply. Its output stage is optimized to reduce switching current during transitions and minimize power supply glitches. Typical uses include sensor signal detection, photodiode preamplifiers, digital line receivers, keyless entry systems, and threshold detectors. Additional specifications include rail-to-rail output swing, an operating temperature range from -40°C to 125°C, input offset voltage of ±1mV, input bias current of 8nA, and robust performance with no phase reversal for overdriven inputs. The device has a power supply rejection ratio and common-mode rejection ratio of 100dB each. Note that due to high market demand, lead times may be extended, and delivery dates can fluctuate. This product is not eligible for discounts.
