Monolithic Linear IC
ISO/IEC-14443 (proximity) RF amplifier
for contact-less IC card and tag
Overview
The LA7209V is a ISO/IEC-14443 (proximity) RF amplifier for contact-less IC card and tag.
Features
• Driver amplifier for ASK modulation (under 500mW) :
Modulation and output level be able to changing by out side constant.
• Diode detector (bridge connecting) : Abstract the data by envelope detector.
• Band pass filter (10kHz to 1MHz) : Data frequency bandwidth pass filter.
• Variable gain amplifier + fixed gain amplifier :
Choosing the wide range output level by additional fixed gain amplifier.
• Comparator (10mVp-p to 2Vp-p) : Converting to the pulse signal of 0/5 volts from small signal.
• Regulator (2V) : Can be use the VCC = 2.7V to 6.0V (recommend VCC : 3V ±10% or 5V ±10%)
• Type changeover switch (card type A/B, C) : All smart card and RF-tag can be read and write by TYPE_CTL.
• Power save (mute) changeover switch : Power save (= 650μA) and output mute can be setting by PWR_CTL.
