Description

The A21SP16 is a differential class-D BTL power

amplifier. It is able to drive up to 2.3 W into a 4



load and 1.4 W into a 8

 load at 5 V. It achieves

outstanding efficiency (88% typ.) compared to

classical Class-AB audio amps.

The gain of the device can be controlled via two

external gain-setting resistors. Pop & click

reduction circuitry provides low on/off switch

noise while allowing the device to start within 5

ms. A standby function (active low) allows the

reduction of current consumption to 10 nA typ.
