EM4294 13.56MHz Crypto Analogue Front End Circuit For High Secure RFID Communication


Posted on Feb 7, 2014

The EUA2032 is a high efficiency, 2. 5W mono class-D Audio Power Amplifier A new developed filterless PWM modulation architecture further reduces EMI and THD+N, as well as eliminates the LC output Filter reducing external component count, system cost, and simplifying design. Operating in a single 5V supply, EUA2032 is capable of driving 4 speake

r load at a continuous average output of 2. 5W/10% THD+N or 2W/1% THD+N. The EUA2032 has high efficiency with speaker load compared to a typical class AB Amplifier With a 3. 6V supply driving an 8 speaker, the efficiency for a 400mW power level is 84%. In cellular handsets, the earpiece, speaker phone, and melody ringer CAN each be driven by the EUA2032. The gain of EUA2032 is externally configurable which allows independent gain control from multiple sources by summing signals from separate sources. The EUA2032 is available in space-saving WCSP and TDFN packages. By Eutech Microelectronics Inc
