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.
