The SM5025A/B is an infrared remote control encoder LSI utilizing CMOS technology. The transmission code consists of "leader pulse", "16 bit customer code", and "16 bit data code". Using Micro-processors for decoder, various applications can be realized.
* Low voltage operation ......VDD = 2.0 to 3.3V
* Low power consumtpion ..... IDD < 1 A at standby mode
* 64 function keys and 3 double action keys
* 128 + 6 function codes are available. (Using SEL terminal)
* 65536 customer codes can be selected. (Using external R, Diode-SM5025A or internal MASK ROM-SM5025IRB)
DESCRIPTION The M62456FP Integrated Circuit is developed for audio-visual equipment. It being used for controld sound in the power amplifier front stage. It has BASSBOOST circuit corresponding to BTL type driver.
FEATURES 24Pin SSOP Build in diode clip circuit Corresponding to BTL type driver. Boost level control (3 steps)
GENERAL DESCRIPTION The AK4522 has a dynamic range of 100dB and is well-suited middle-range MD, surround system, musical instruments and car audio. Signal inputs and outputs are single-ended. The DAC outputs are analog filtered to remove out of band noise. External components are minimized. The AK4522 is available in a small 24Pin VSOP package, which will reduce system space.
