What is Arduino
- Arduino® is an open-source prototyping platform based on easy-to-use hardware and software. Arduino® boards are able to read inputs – a light-on sensor, a finger on a button, or a Twitter message – and turn it into an output – activating a motor, turning on an LED, and publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming language (based on Wiring) and the Arduino® software IDE (based on Processing). Additional shields/modules/components are required for reading a Twitter message or publishing online. Surf to www.arduino.cc for more information.
Product Overview
- The WPI446 (PAM8610) is a 10 W (per channel) stereo class-D audio amplifier with DC volume control, which offers low THD+N (0.1%), low EMI, and good PSRR thus high-quality sound reproduction. The 32-steps DC volume control has a +32 dB to -75 dB range.
- 10 W @ 10% THD/channel output into an 8 Ω load at 13 V
- low noise: -90 dB
- over 90% efficiency
- 32-step DC volume control from -75 dB to + 32 dB
- shutdown/mute/fade function
- over current, thermal and short-circuit protection
- low THD+N
- low quiescent current
- pop noise suppression
- 4 Ω speakers can be used as well (gives max. 15 W). However, we recommend putting a small cooler on the PAM8610 if using 4 Ω loads.
Specifications
- supply voltage (Vdd): 7-15 V
- input voltage range (Vi)
- mute, Vref, volume, fade: 0-6.0 V
- SD: -0.3 to Vdd
- RINN, RINP, LINN, LINP: -0.3 to 6.0 V
- junction temperature range (Tj): -40 to 125 °C
- output power @ 8 Ω: 10 W
Connection
Recommended cables for connecting WPI446: BTWF2 (4 x) and BTWF3 (1 x).
