The AD9609 operates from a single 1.8 V analog powersupply and features a separate digital output driver supplyto accommodate 1.8 V to 3.3 V logic families.2. The sample-and-hold circuit maintains excellent performancefor input frequencies up to 200 MHz and is designed for lowcost, low power, and ease of use.3. A standard serial port interface supports various productfeatures and functions, such as data output formatting,internal clock divider, power-down, DCO and data output(D9 to D0) timing and offset adjustments, and voltagereference modes.4. The AD9609 is packaged in a 32-lead RoHS compliantLFCSP that is pin compatible with the AD9629 12-bit ADCand the AD9649 14-bit ADC, enabling a simple migrationpath between 10-bit and 14-bit converters sampling from20 MSPS to 80 MSPS.

The AD9609 is a monolithic, single channel 1.8 V supply, 10-bit,20/40/65/80 MSPS analog-to-digital converter (ADC). It featuresa high performance sample-and-hold circuit and on-chip voltagereference.The product uses multistage differential pipeline architecturewith output error correction logic to provide 10-bit accuracy at80 MSPS data rates and to guarantee no missing codes over thefull operating temperature range.The ADC contains several features designed to maximize flexibilityand minimize system cost, such as programmable clock and dataalignment and programmable digital test pattern generation. Theavailable digital test patterns include built-in deterministic andpseudorandom patterns, along with custom user-defined testpatterns entered via the serial port interface (SPI).A differential clock input with selectable internal 1 to 8 divide ratiocontrols all internal conversion cycles.
