GENERAL DESCRIPTION
0.18µm 8-BIT 800K ADC
The adc1295x is a CMOS 8bit A/D converter which combines an auto offset calibration comparator, high resolution
R-string DAC, clock generator, 8bit successive approximation register (SAR), output register, and AINC which
controls analog input selection. The adc1295x provides software-selection power-down mode. The device operates
with a single +3.3V supply and A/D conversion rate is 800KSPS, external clock XP1 is 40MHz. The operating
temperature range is -40–85 °C for commercial specification.

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 1.5kΩ resistor (Human body model)
