The SQ82948 integrated 48 channel 12-bit, digital-to-analog converters (DACs), a 6 to1 multiplexed with a channel 12-bit analog to- digital converter (ADC), a temperature sensor, and an internal reference. The multiplex can be configuring as GPIO as well.
The SQ82948 DAC output range can be programmable (-10 ~ 0V, 0V ~ 10V) which is good for the power amplifiers (PA) in MIMO communication systems.
