BCT8002H
The BCT8002H audio power amplifier is ideal for portable audio devices with internal speakers. A bridge-tied load (BTL) architecture minimizes external component count, while providing high-quality audio reproduction. The device is available as adjustable gain amplifier, reducing component count.
A low-power enable mode disables the bias generator and amplifiers, reducing quiescent current consumption to less than 1uA. This device feature Broadchip’s industry-leading, comprehensive click-and-pop sup-pression that reduces audible clicks and pops during startup and enable.
The BCT8002H is available in 8-pin SOP8 package. This device operates over the -40°C to +85°C extended temperature range.
