12BIT 10MSPS ADC
BL8531H_ADC
GENERAL DESCRIPTION
FEATURES
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.
