General Description
The APA3010/1 is a bridged-tied load (BTL) audio power
amplifier developed especially for low-voltage applications where internal speakers. Operating with a 5V supply,
the APA3010/1 can deliver 3.3W of continuous power into
a BTL 3W load at 10% THD+N throughout voice band
frequencies. Although this device is characterized out to
20kHz, its operation is optimized for narrow band applications such as wireless communications. The BTL configuration eliminates the need for external coupling capacitors on the output in most applications, which is particularly important for small battery-powered equipment.
This device features a shutdown mode for power sensitive applications with special depop circuitry to eliminate
speaker noise when exiting shutdown mode. The
APA3010/1 are available in a SOP-8, SOP-8P or
MSOP-8P.
