Power chip makes the most of a single cell
A buck-boost power management IC helps extend battery life in smart phones, digital still cameras and other single-cell lithium-ion powered multimedia devices.
Beyond video, the device can also be used in other high-speed signal multiplexing applications.
The devices allow the multiplexing of large amounts of data, such as high-resolution professional video signals, at higher speeds than previous generations.
The OPA875 single-channel and OPA3875 three channel 2:1 multiplexers feature a small signal bandwidth of 700MHz with a slew rate of 3100V/us, which supports a large signal bandwidth of 425MHz at 4Vpp.
The OPA4872 single-channel 4:1 multiplexer offers a slew rate of 2300V/us for a bandwidth of 500MHz at 2Vpp.
The devices use a low-glitch switching technique to enable fast and seamless multiplexing of high-speed signals.
