General Description
The HT82A850R is an 8-bit high performance RISC-like
microcontroller designed for USB Phone product appli-
cations. The HT82A850R integrates a 16-bit PCM ADC
and an 8-bit MCU into a single device. The DAC in the
HT82A850R 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 am-
plifier, whose gain ranges from 32dB to +6dB. For the
ADCinput,thedigitalgainrangeisfrom0dBto19.5dB.
