The AS1702, AS1703, AS1704, and AS1705 are singlechannel differential audio power-amplifiers designed to drive 4 and 8Ω loads. The integrated gain circuitry of these amplifiers and their small size make them ideal for 2.7- to 5V-powered portable audio devices.
The differential input design of AS1703 improves noise rejection and provides common-mode rejection. A bridge-tied load (BTL) design minimizes external component count,while providing Hi-Fi audio power amplification.AS1703 deliver 1.6W continuous average power per channel to a 4Ω load with less than 1% total harmonic distortion (plus noise), while operating from a single 2.7 to 5V supply.
In order to facilitate reduced component designs, the devices are available with different gain levels:
AS1702 Adjustable Gain (via external components)
AS1703 AV = 0dB
AS1704 AV = 3dB
AS1705 AV = 6dB
Integrated shutdown circuitry disables the bias generator and amplifiers, and reduces quiescent current consumption to less than 100nA. The shutdown input of AS1703 can be set as active-high or active-low. All devices contain comprehensive click-and-pop suppression circuitry that reduces audible clicks and pops during power-up and shutdown.
The AS1702, AS1703, AS1704, and AS1705 are pin compatible with the LM4895 and the MAX9718A/B/C/D. The devices are available in a 10-pin MSOP package.
