T2526

Features www.DataSheet4U.com No External Components Except PIN Diode Supply-voltage Range: 2.7V to 5.5V Highest Sensitivity Due to Automatic Sensitivity Adaption (AGC) and Automatic Strong Signal Adaption (ATC) Automatic Supply Voltage Adaptation Highest Immunity against Disturbances from Daylight and Lamps Available for Carrier Frequencies between 30 kHz to 76 kHz; adjusted by Zener-Diode Fusing ±2.5% TTL and CMOS Compatible Applications Home Entertainment Applications (Audio/Video) Home Appliances Remote Control Equipment Low-voltage IR Receiver ASSP T2526 1. Description The IC T2526 is a complete IR receiver for data communication developed and optimized for use in carrier-frequency-modulated transmission applications. The IC offers highest sensitivity as well as highest suppression of noise from daylight and lamps. The T2526 is available with broadest range of frequencies (30, 33, 36, 37, 38, 40, 44, 56, 76 kHz) and 5 different noise suppression regulation types (standard, lamp, noise, short burst, data rate) covering requirements of high-end remote control solutions (please refer to selection guide available for T2525/T2526). The T2526 operates in a supply voltage range of 2.7V to 5.5V. The function of the T2526 can be described using the block diagram of Figure 1-1 on page 2. The input stage meets two main functions. First it provides a suitable bias voltage for the PIN diode. Secondly the pulsed photo-current signals are transformed into a vol...
