Description

The HT82A850R is an 8-bit high performance RISC-like microcontroller designed for USB Phone product applications.
The HT82A850R integrates a 16-bit PCM ADC and an 8-bit MCU into a single device. The DAC in it operates at a sampling rate of 48/8kHz and the 16-bit PCM ADC operates at a frequency of 8kHz for the Microphone input. The DAC in the HT82A850R also has a digital programmable gain amplifier, whose gain ranges from -32dB to +6dB. For the ADC input, the digital gain range is from 0dB to 19.5dB.
