12BIT 10MSPS ADC
GENERAL DESCRIPTION
The BL8531H_ADC is a CMOS 12bit analog-to-digital
converter (ADC).
It converts the analog input signal
into
12bit
binary
digital
sampling rate of 10MHz.
The device is a monolithic ADC with an on-chip,
high-performance, sample-and-hold Amplifier (SHA)
and current referenc.
differential and single-ended input.
This 12bit ADC has also 3 channel MUX, so 3
channel inputs are acceptable.
TYPICAL APPLICATIONS
CCD Imaging (Copiers, Scanners, Cameras)
