AS1705V - AMP AUDIO MONO 1.8W SMD DFN10

General Description
The AS1702 - AS1705 are single-channel differential audio power-
amplifiers designed to drive 4 and 8Ohm loads. The integrated gain cir-
cuitry of these amplifiers and their small size make them ideal for
2.7- to 5V-powered portable audio devices.
The differential input design improves noise rejection and provides
common-mode rejection. A bridge-tied load (BTL) design minimizes
external component count, while providing high-fidelity audio power
amplification.
The devices deliver 1.8W continuous average power per channel to
a 4Ohm load with less than 1% total harmonic distortion (plus noise),
while operating from a single 2.7 to 5V supply.
For reduced component designs, the devices are available with dif-
ferent gain levels as shown in the table below:

Integrated shutdown circuitry disables the bias generator and ampli-
fiers, and reduces quiescent current consumption to less than
100nA. The shutdown input can be set active-high or active-low. All
devices contain click-and-pop suppression circuitry that reduces
audible clicks and pops during power-up and shutdown.
The AS1702 - AS1705 are pin compatible with the LM4895 and the
MAX9718A/B/C/D. The devices are available in a 10-pin MSOP
package and a 10-pin DFN package.
