ATA2526
Low-voltage IR Receiver ASSP
DATASHEET
Features
● No external components except PIN diode
● Supply-voltage range: 2.7V to 5.5V
● High sensitivity due to automatic sensitivity adaption (AGC) and automatic strong
signal adaption (ATC)
● Automatic supply voltage adaptation
● High immunity against disturbances from daylight and lamps
● Small size and innovative pad layout
● Available for carrier frequencies between 33kHz to 40kHz and 56kHz; adjusted by
zener diode fusing ±2.5%
● TTL and CMOS compatible
Applications
● Home entertainment applications
● Home appliances
● Remote control equipment
