AD9203ARURL7 Datasheet

Analog to Digital Converters - ADC


The AD9203ARURL7 is a monolithic low power, single supply, 10-bit, 40 MSPS analog-to-digital converter, with an on-chip voltage reference. The AD9203ARURL7 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 AD9203ARURL7 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 operating at lower sampling rates. This yields power savings for users who do not require the maximum sample rate. This feature is especially useful at sample rates far below 40 MSPS. Excellent performance is still achieved at reduced power. For example, 9.7 ENOB performance may be realized with only 17 mW of power, using a 5 MHz clock. AD9203ARURL7 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 AD9203ARURL7 Applications • CCD imaging • Video• Portable instrumentation • IF and baseband communications • Cable modems• Medical ultrasound
