AMP2X1 Audio Amplifier Board

PUI Audio amplifier boards feature a Class D stereo amplifier integrated circuit for maximum signal fidelity

Image of PUI Audio AMP2X1 Audio Amplifier BoardPUI Audio AMP2X1 audio amplifier board features an Analog Devices MAX9710 Class D stereo amplifier integrated circuit for maximum signal fidelity. This amplifier delivers 1.4 W per channel into 8 Ω loads and 2.6 W per channel into 4 Ω loads, both at 1% THD+N while using a 5 VDC supply.

The board features a small size of 27.9 mm x 38.0 mm and header pins for easy design prototype development.

Features
  • 1.4 W per channel into 8 Ω loads, THD <1%
  • 2.6 W per channel into 4 Ω loads, THD <1%
  • Enhances system performance that includes:
    • Transient suppression when the supply voltage is applied
    • High 100 dB PSRR (VRIPPLE = 200 mVP-P)
  • Low quiescent current
  • Extends battery life for portable applications
  • Thermal overload protection
  • Short-circuit protection
  • Power supply range: 4.5 V ≤ VDD ≤ 5.5 V
  • 12 mA supply current (VDD = 5.0 V)
  • POUT = 1.4 W into 8 Ω (THD = 1%, VDD = 5.0 V)
  • POUT = 2.6 W into 4 Ω (THD = 1%, VDD = 5.0 V)
  • External resistors adjust the amplifier gain
  • 2 V logic-compatible SHDN input
  • 100 mil spaced header pins for input, output, shutdown, and power supply
