High-speed voice and data switches from Intersil
Intersil has introduced the ISL54210 and ISL54211, highly-integrated devices that extend Intersil’s leadership position in compact, high-performance mixed audio and data switches. The ISL54210 and ISL54211 combine superior low distortion performance, high-speed USB 2.0 data rates and use the industry’s most effective suppression technology to eliminate clicks and pops in handheld devices.The
The ISL54210 is optimised for powering off an LDO regulator and includes circuitry for the detection of the USB VBUS voltage, which is used to switch between the audio and USB signal sources. The ISL54211 can operate off a Lithium Ion battery supply, and has logic control pins that are 1.8V logic compatible, allowing for direct control via a standard microcontroller.
The ISL54210 and ISL54211 are available now in 1.8mm x 1.4mm x .50 μTQFN, 10 Ld 3 x 3 TDFN, and 10 Ld 3 x 3 TDFN T+R packages.
