ADC1280X
0.18µm 10-BIT 30MSPS ADC µ
GENERAL DESCRIPTION
The ADC1280X is a CMOS 10-bit low-voltage and high-speed A/D converter (ADC) for video and other applications. It has a four-step pipelined architecture, which consists of the sample & hold amplifier, multiplying D/A converters (DACs), and subranging flash ADCs. The maximum conversion rate of ADC1280X is 30MSPS and supply voltage is 1.8V single.
FEATURES
-- Resolution : 10-bit -- Maximum Conversion Rate : 30MSPS -- Power Supply : 1.8V Single -- Differential Linearity Error : ± 1.0 LSB -- Integral Linearity Error : ± 2.0 LSB -- Sample & Hold Function Implemented -- Low Power Consumption : 21.6mW(Typ) -- Operating Temperature Range : -40 °C 85 °C
TYPICAL APPLICATIONS
-- CCD imaging processors Camcorders, scanners, and security cameras. -- Read channel LSI HDD, DVD, and CD-ROM drives -- IF and baseband signal digitizers -- Portable equipments for low-power applications

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 VS S unless otherwise specified. 3. 100pF capacitor is discharged through a 1.5K resistor (Human body model)
