Audio Codec Processor
Trade Description
Product Feature
The H7A36QP is compatible with H244QP, and provides more powerful analog device and digital mathematic circuit. It features the microphone input and differential amplifier for high quality audio input and high resolution ADC for analog sampling.
The H7A36QP equips a math-processor (II) for processing the mathematical algorithms that can be implemented to a high-compressed speech encoder and decoder or the speech recognition …etc.
There are NAND interface and SPI bus for interfacing to the external storage, and 2-wire serial bus for linking with the other device or MCU.
For voice input, the H7A36QP also equips the differential amplifier for microphone input and AGC (auto gain control) for good SNR voice signal input.
Not only the good pre-amplifier is embedded but also the high-end delta-sigma DAC and class-AB speaker amplifier can drive and output the high-quality sound.
