It is a high-speed, low-power, 16-bit successive approximation ADC in a 20-pin QSDP package or 20-pin SSOP package and operates from a single 2.7V to 5V supply with a maximum sample rate of 100kHz and a signal to noise ratio of 84dB. There is a serial interface that contains eight single-ended analog input channels (CH0 ~ CH7). It can also be combined into four differential inputs. Typical power consumption at 100kHz is 10mV. The reference voltage VREF ranges from 500mV to VCC, and the corresponding input of each analog channel is from 0V to VREF. Built-in sampling / holding function, the operating temperature range of -40 ℃ ~ +85 ℃.
