1 / 33 page Datasheet ○ Product structure : Silicon monolithic integrated circuit ○ This product is not designed protection against radioactive rays. 1/30 TSZ02201-0C2C0E100140-1-2 © 2014 ROHM Co., Ltd. All rights reserved. 13.MAR.2014 Rev.001 www.rohm.com TSZ22111 ・14・001 Analog Sound Processors series Sound Processor for car audio built-in 2 nd order post filter BD37067FV-M Structure It is built-in input selector of 6 stereo source and output to ADC after adjusting signal level. And built-in 2 nd order post filter to reduce out of band noise and 6ch Volume circuit. Moreover, it is simple to design set by built-in TDMA noise reduction systems. Feature 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 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 I 2C-BUS controller AEC-Q100 Qualified. Applications It is the optimal for the car audio. Besides, it is possible to use for the audio equipment of mini Compo, micro Compo, TV.
