Mxx AYWW NCP2820 Series 2.65 W Filterless Class-D Audio Power Amplifier The NCP2820 is a cost effective mono ClassD audio power amplifier capable of delivering 2.65 W of continuous average power to 4.0 from a 5.0 V supply in a Bridge Tied Load (BTL) NCP2820 Series PIN CONNECTIONS 9Pin FlipChip CSP UDFN8 1 8 OUTM SD A1 A2 A3 INP GND OUTM 2 GND VP 7 B1 B2 B3 3 6 INP VP VP VP GND INM 4 5 OUTP C1 C2 C3 (Top View) INM SD OUTP (Top View) BATTERY Cs V p R R i f INM OUTP RAMP GENERATOR Data CMOS Negative Processor Output Differential Stage Input OUTM R R f i INP 300 k Shutdown Positive GND Control Differential SD Input V ih V il Figure 1. Typical Application PIN DESCRIPTION Pin No. CSP UDFN8 Symbol Type Description A1 3 INP I Positive Differential Input. A2 7 GND I Analog Ground. A3 8 OUTM O Negative BTL Output. B1 2 V I Analog Positive Supply. Range: 2.5 V 5.5 V. p B2 6 V I Power Analog Positive Supply. Range: 2.5 V 5.5 V. p B3 7 GND I Analog Ground. C1 4 INM I Negative Differential Input. C2 1 SD I The device enters in Shutdown Mode when a low level is applied on this pin. An internal 300 k resistor will force the device in shutdown mode if no signal is applied to this pin. It also helps to save space and cost. C3 5 OUTP O Positive BTL Output.
