NCP2830/D
NCP2830
1W Constant Filterless
Class-D Audio Amplifier
NCP2830 is a cost effective mono audio power amplifier designed
for portable communication device applications such as mobile
phones. Due to its integrated charge pump structure, this part is
capable of delivering 1 W of continuous average power to an 8.0
W
Bridge Tied Load no matter the voltage provided by a lithium/Ion
battery.
NCP2830 is a preferred solution for long playback audio with
minimum space required.
Added to a fast startup time of 200
ms and a 88dB PSRR, the
NCP2830 audio power amplifier is specifically designed to provide
high quality and level output power from low supply voltage,
requiring very few external components.
Features
1 W to 8 W load for VDD from 2.7 V up to 5.5 V
High quality audio (THD+N = 0.04%)
Low noise: SNR up to 100 dB
Very Fast Turn On Time: 200 ms
Overall system efficiency optimization: up to 89%
Superior PSRR (88 dB): Direct Connection to Battery
Very Low Quiescent Current 7 mA
Optimized PWM Output Stage: Filterless Capability
Selectable gain of 2 V/V or 4 V/V
Fully Differential Capability:
Thin QFN 3x3 mm, 20 pins
This Device uses HalogenFree Molding Compound
This is a PbFree Device
Typical Applications
Cellular Phones and Digital Cameras
Personal Digital Assistant and Portable Media Player
Audio Accessories
GPS
