LM2903AVQDR Texas Instruments Profile

LM2903AVQDR is a dual voltage comparator integrated circuit (IC) designed and manufactured by Texas Instruments. This IC is a low-power, general-purpose comparator with a wide-range single supply voltage. Its small size and low power consumption make it ideal for battery-powered and portable applications.

The LM2903AVQDR has two independent voltage comparators that can operate in both open-loop and closed-loop configurations. It is capable of comparing voltages at two different input terminals and outputs a logical signal that indicates which input voltage is greater than the other.

This IC supports a wide voltage range, from 2V to 36V, and can operate at temperatures from -40°C to +125°C. It has a response time of 1.3µs at 5V, making it suitable for high-speed applications. LM2903AVQDR also has low input bias current and low offset voltage, ensuring accuracy and precision in voltage detection and comparison.

LM2903AVQDR features include an open-drain output, low output saturation voltage, and wide input common-mode voltage range. The device is available in a small surface mount package (SOIC-8).
