2 order post filter
BD37068FV-M
General Description
It is built-in input selector of 6 stereo source and output
nd
to ADC after adjusting signal level. And built-in 2 order
post filter to reduce out of band noise and 6ch Volume
circuit. It is possible to out until 5.2V
RMS
at maximum
output. (High Voltage function) Moreover, it is simple to
design set by built-in TDMA noise reduction systems.
Key Specifications
(Note1)
Features
AEC-Q100 (Grade3) Qualified
Built-in differential input selector that can select
single-ended / differential input
Reduce the pop noise when switching gain due to
built-in advanced switch circuit
nd
Less out-of-band noise of DAC by built-in 2 order
post filter.
Built-in buffered ground isolation amplifier to realize
high CMRR characteristics
Built-in TDMA noise reduction circuit reduces the
additional components for external filter.
It is possible to output 5.2V
RMS
by High-Voltage
function
Package is SSOP-B40. Putting same direction
input-terminals and output-terminals make PCB
layout easier and PCB area smaller.
