PA3017

UNISONIC TECHNOLOGIES CO., LTD PA3017 2W STEREO AUDIO AMPLIFIER  DESCRIPTION As a stereo audio speaker which is operating on a single 5V supply, the UTC PA3017 is capable of delivering 2W of output power per channel into 3Ω loads with less than 1% THD+N. Way of two terminals (GAIN0 and GAIN1) can configured and control the amplifier gain. It also provide gain settings of 6 dB, 10 dB, 15.6 dB, and 21.6 dB (inverting). Other features include internal gain control which requires few external components, an active-low shutdown mode input and thermal shutdown protection.  FEATURES * 2W output power into 3Ω load from 5V supply each channel * Gain control internally * Differential input fully * Depop circuitry * Shutdown protection thermally  ORDERING INFORMATION Ordering Number PA3017G-N20-R Package HTSSOP-20 CMOS IC Packing Tape Reel  MARKING www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 10 QW-R502-224.C PA3017  PIN CONFIGURATION CMOS IC  PIN DESCRIPTION PIN NO. 1,11 13,20 2 3 4 5 6,15 7 8 9 10 12 14 16 17 18 19 PIN NAME GND GAIN0 GAIN1 LOUT+ LINPVDD RIN+ LOUTLIN+ BYPASS NC ROUTVDD RINROUT+ SHUTDOWN I/O DESCRIPTION Ground I Bit 0 of gain control I Bit 1 of gain control O Positive output for left channel I Negative differential input for left channel I Supply voltage I Positive differential input for right channel O Negative output for left channel I Positive differential input for left channel Tap to voltage divider for internal mid su...
