特点：
- Built-in differential input selector that can select single-ended / differential input
- Reduce the shock noise when switching gain due to built-in advanced switch circuit
- Decrease the out of band noise of DAC by built-in 2nd order post filter.
- Built-in buffered ground isolation amplifier to realize high CMRR characteristics
- No need to countermeasure using external components built-in TDMA noise reduction circuit
- It is possible to output 5.2Vrms by High-Voltage function
- Package is SSOP-B40. Putting same direction input-terminals and output-terminals make PCB layout easier and PCB area smaller.
- It is possible to control by 3.3V for I²C-BUS controller
- AEC-Q100 Qualified.
