CXA1511L Datasheet | Sony Semiconductor Solutions

Description The CXA1511L/M is a bipolar IC used for preamplifiers that receive signals in infrared remote control systems. These ICs consist of a first-stage amplifier, limiter amplifier, band-pass filter, band elimination filter, signal waveform detection circuit and waveform shaping circuit. Features - Low power consumption (VCC = 5V, 9m W typ.) - Low supply voltage (VCC = 5V) - Filters (center frequency can be varied through external resistor: fo = 30k Hz to 60k Hz, 40k Hz typ.) - Elimination of inductors prevents magnetic field inductance interference. - Optical reception diode can be coupled directly. - Collector output (pull-up resistor, TTL and CMOS can be connected directly) Applications TVs, VCRs, audio equipment Structure Bipolar silicon monolithic IC Block Diagram and Pin Configuration 8 pin SIP (Plastic) 8 pin SOP (Plastic) Absolute Maximum Ratings 7 V - Supply voltage VCC - Operating temperature Topr - 20 to +75 °C - Storage temperature Tstg - 65 to +150 °C - Allowable power dissipation PD 600 m W (SIP) - Allowable power dissipation PD 300 m W (SOP) Operating Conditions - Supply voltage 4.7 to 5.3 Head Amp IN 1 ABLC Photo Diode Limiter Amp BPF Delector & Hysteresis BEF parator Integralor parator 2 C1 470, 680 0.01µ 3 4 5 6 C2 GND fo N.C. 7 8 OUT VCC 0.01µ 200k (fo = 40k Hz) VCC = 5V Sony reserves the right to change products and specifications without prior notice.
