MAX921CPA Description

Short technical summary and product information.

The MAX921CPA from Analog Devices is a single, micro-power, low-voltage comparator designed for efficient operation in battery-powered systems. It features an internal 1.182V ±1% bandgap voltage reference and offers programmable hysteresis.

 

This comparator draws ultra-low quiescent current, typically less than 4µA, making it ideal for power-sensitive applications. It supports single supply operation from +2.5V to +11V or dual supplies from ±1.25V to ±5.5V. The input voltage range includes the negative supply rail.

 

The MAX921CPA has TTL/CMOS-compatible outputs and a propagation delay of 12µs with a 10mV overdrive. Its unique output stage can continuously source up to 40mA. The device is housed in an 8-pin PDIP package and is suitable for through-hole mounting.

 

Key features include adjustable hysteresis, no switching crowbar current, and a typical CMRR/PSRR of 80dB. The operating temperature range is 0°C to 70°C.
