Unisonic Technologies PA7493
PA7493 provides precise DC volume control, and a stereo bridged audio power amplifiers capable of producing 2W into 4Ω as a monolithic integrated circuit. It is suitable for small or portable products.DESCRIPTION
UTC In stand-by the power consumption is very low. UTC PA7493 combines a stereo single-end (SE) mode for headphone drive into a single chip and a stereo bridge-tied loads (BTL) mode for speaker drive(both modes are easily switched by the SE/BTL input control signal) to simplify the audio system design. Package size is not occupies PCB space cause the built-in over-temperature protection. It is suitable for small or portable products.●
