 BL8531H-ADC
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.

NOTES
1. Absolute maximum rating specifies the values beyond which the device may be damaged permanently. Exposure to
ABSOLUTE MAXIMUM RATING conditions for extended periods may affect reliability. Each condition value is
applied with the other values kept within the following operating conditions and function operation under any of these
conditions is not implied.
2. All voltages are measured with respect to VSS unless otherwise specified.
3. 100pF capacitor is discharged through a 1.5kresistor (Human body model)
