CXA2513M

CXA2513M 3-Band Preset Graphic Equalizer IC (with standby and memory on last preset mode) Description The CXA2513M is a 3-band preset graphic equalizer developed for stereo set, cassette tape recorder with radio, etc. It has 5 modes: FLAT, ROCK, VOCAL, POP and JAZZ. The selection is via 5 control pins. The center frequencies of three bands are 100Hz, 1kHz and 10kHz. The center frequencies of these bands are determined by 2 external resistors. It also has a standby feature. When the standby pin goes low, the IC stores the last preset mode. When this pin goes high, the IC restores the last preset mode before standby. It can be initialized to any one of the two preset modes (FLAT, ROCK) upon power up. Features Very few external parts 3-band monolithic filters (100Hz, 1kHz, 10kHz) The center frequencies of the band-pass filters can be adjusted 5 preset modes (FLAT, ROCK, VOCAL, POP, JAZZ) Equips with output ports to drive external LEDs Mute pulse output pin Standby feature with last preset mode memory Can be initialized to one of the two preset modes (FLAT or ROCK) Applications Preset graphic equalizer for cassette tape recorder with radio and portable stereo Structure Bipolar silicon monolithic IC 20 pin SOP (Plastic) Absolute Maximum Ratings (Ta = 25°C) Supply voltage VCC 12 V Allowable power dissipation PD 600 mW Storage temperature Tstg –65 to +150 °C Recommended Operating Conditions Supply voltage VCC 4.5 to 10 Operating temperature Topr –20 to +75...
