Product Overview
AMP2X2 is an audio amplifier board. It features an Analog Device’s MAX9744 Class D stereo amplifier circuit for maximum signal fidelity. This amplifier delivers a minimum of 2.0W per channel into 8ohm loads and 4.0W per channel into 4ohm loads, both at less than 1% THD+N while using a 7V DC supply. The board features a small size of 38.0mm x 38.0mm and header pins for easy design prototype development.
- Low quiescent current
- Thermal overload protection and short-circuit protection
- Minimum amplifier power supply of 7V and subsystem power supply voltage range: 2.7V to 3.6V
- 7mA subsystem power supply current (VDD=3.3V) and 4mA amplifier power supply current (PVDD = 7.0V)
- External resistors adjust the amplifier gain
- 1.8V logic-compatible SHDN input
- Signal-to-noise ratio of 89dB at A-weighted, VDD = 7V, POUT = 2W, RL = 8ohm + 33mH
- 200ms typ turn-on time
- 68dB typ power-supply rejection ratio at VDD = 2.7V less than equal to V DC less than equal to 3.6V
