CA3290BT Description

Short technical summary and product information.

The CA3290BT is a dual general-purpose comparator designed by Harris Semiconductor. It contains two independent open-collector output stages, allowing wired-OR connections and direct interface with logic circuits. The device operates from a single supply voltage up to 36V or dual supplies up to ±18V, offering flexibility in various power configurations.

 

Key electrical characteristics include a maximum input offset voltage of 20mV at ±15V, a maximum input bias current of 50pA, and a typical output current of 30mA. The quiescent current is limited to 3mA maximum, and the common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) are typically 87dB and 96dB respectively. The comparator is specified over the full industrial temperature range of -55°C to 125°C.

 

The CA3290BT is packaged in a through-hole TO-205AA (TO-5-8) metal can, suitable for applications requiring robust mechanical mounting. Its open-collector outputs make it ideal for level detection, window comparators, and interface circuits where multiple outputs can be connected together. The part is RoHS3 compliant.
