RS8901XF

Comparators Overview

The RS8901XF is a single-channel CMOS comparator manufactured by Runic Technology, housed in an SOT-23-5 surface-mount package. It operates on a single or dual supply voltage ranging from 1.4V to 5.5V. The device features low input bias current of 10pA at 5.5V and typical static current consumption of 1.5µA. Output characteristics include a push-pull, rail-to-rail CMOS configuration with a typical output current of 42mA at 5V. Electrical specifications indicate a maximum propagation delay of 13µs, maximum input offset voltage of 3mV at 5V, and typical CMRR/PSRR of 70dB. It functions within an operating temperature range of -40°C to 125°C.

Comparators Feature Summary

• CMOS technology enabling low power consumption and rail-to-rail output swing
• Single-channel architecture optimized for compact surface-mount designs
• High input impedance with minimal bias current requirements

Comparators Applications

• Battery-powered portable electronics requiring low quiescent current
• Threshold detection circuits in consumer devices
• Signal conditioning in automotive body electronics

Comparators Procurement Notes

Verify the specific suffix 'XF' against the manufacturer's official datasheet to confirm pinout and electrical tolerances. Ensure compatibility with the SOT-23-5 footprint during PCB layout. Confirm RoHS3 compliance status if required by assembly standards. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Comparators Selection Notes

Select this component when a single comparator with ultra-low input bias current is required in a small form factor. The wide supply voltage range supports both 1.8V and 3.3V logic systems. Consider the 13µs propagation delay for non-high-speed applications. Verify that the push-pull output stage meets the load requirements of the downstream circuitry without additional buffering.

Comparators Part Context

This part belongs to the nano-power comparator series from Runic Technology, designed for energy-efficient analog signal processing. It complements other precision operational amplifiers and comparators in the manufacturer's portfolio, targeting cost-sensitive consumer and industrial markets. The SOT-23-5 packaging allows for high-density board layouts compared to larger through-hole alternatives.
