ADC1275X_PC

0.18µm 10-BIT 500KSPS ADC µ

GENERAL DESCRIPTION
The ADC1275X_PC is a CMOS 3.3V 10-bit analog-to-digital converter (ADC). It converts the analog input signal into 10-bit binary digital codes at a maximum conversion rate of 500KSPS with 2.5MHz clock. The device is a recycling type monolithic ADC with an on-chip sample-and-hold function. The ADC has power down mode.

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 i s not implied. 2. All voltages are measured with respect to VSS unless otherwise specified. 3. 100pF capacitor is discharged through a 1.5K resistor (Human body model)
