AMP1X1 Single-Channel Audio Amplifier Board

PUI Audio amplifier delivers 1.4 W per channel into 8 Ω loads and 2.1 W per channel into 4 Ω loads

Image of PUI Audio AMP1X1 Single-Channel Audio Amplifier BoardThe PUI Audio AMP1X1 amplifier delivers 1.4 W per channel into 8 Ω loads and 2.1 W per channel into 4 Ω loads at 1% THD+N while using a 5 VDC supply. The board features a small size of 25.4 mm x 25.4 mm and comes with 100 mil spaced header pins for easy design prototype development.

The AMP1X1 offers low, 1.8 mA (typical, VDD = 5 VDC), an excellent 110 dB (typical) SNR, and high linearity expressed in its 0.008% THD+N. The amplifier features circuitry that produces high suppression of output transients when the power supply voltage is applied. isThe amplifier’s power supply rejection ratio (PSRR) is also an outstanding 90 dB.
