简  介:a FEATURES CMOS 10-Bit 40 MSPS Sampling A/D Converter Power Dissipation: 74 mW (3 V Supply, 40 MSPS) 17 mW (3 V Supply, 5 MSPS) Operation Between 2.7 V and 3.6 V Supply Differential Nonlinearity: 0.25 LSB Power-Down (Standby) Mode, 0.65 mW ENOB: 9.55 @ fIN = 20 MHz Out-of-Range Indicator Adjustable On-Chip Voltage Reference IF Undersampling up to fIN = 130 MHz Input Range: 1 V to 2 V p-p Differential or Single-Ended Adjustable Power Consumption Internal Clamp Circuit APPLICATIONS CCD Imaging Video Portable Instrumentation IF and Baseband Communications Cable Modems Medical Ultrasound PRODUCT DESCRIPTION CLAMP CLAMPIN AINP AINN 10-Bit, 40 MSPS, 3 V, 74 mW A/D Converter AD9203 FUNCTIONAL BLOCK DIAGRAM CLK AVDD DRVDD AD9203 A/D SHA A/D D/A GAIN A/D SHA D/A GAIN STBY 3 STATE REFTF REFBF BANDGAP REFERENCE VREF REFSENSE 0.5V + – CORRECTION LOGIC OUTPUT BUFFERS 10 OTR D9 (MSB) D0 (LSB) AVSS PWRCON DFS DRVSS The AD9203 is a monolithic low power, single supply, 10-bit, 40 MSPS analog-to-digital converter, with an on-chip voltage reference. The AD9203 uses a multistage differential pipeline architecture and guarantees no missing codes over the full operating temperature range. Its input range may be adjusted between 1 V and 2 V p-p. The AD9203 has an onboard programmable reference. An external reference can also be chosen to suit the dc accuracy and temperature drift requirements of an application. An external resistor can be used to reduce power consumption when operatin……
