The BL8531H_ADC is a CMOS 12bit analog-to-digital
converter (ADC).
It converts the analog input signal
into
12bit
binary
digital
codes
at
a
maximum
sampling rate of 10MHz.
The device is a monolithic ADC with an on-chip,
high-performance,
sample-and-hold
Amplifier
(SHA)
and
current
referenc.
The
structure
allows
both
differential and single-ended input.
This 12bit ADC has also 3 channel MUX, so 3
channel inputs are acceptable.
