The evalua- tion board was originally designed and used for evaluating the AD9034 A/D converter, but is equally useful for the pin- compatible AD9032. The board includes a reconstruction DAC, analog input ampli- fier, and digital output interface. Physically, it is 7.25 inches 6 inches in size and uses the layout and applications information contained in the AD9034 data sheet. Generous space is provided near the analog input and digital outputs of the evaluation board to support additional signal pro- cessing components the user may wish to add. These two proto- typing areas include through holes with 100-mil centers to support a variety of component additions. For additional operating details, a schematic of the evaluation board, and complete layout information, consult the data sheet on the AD9034 A/D converter. GENERAL DESCRIPTION The AD9032 is the world’s fastest 12-bit analog-to-digital con- verter (ADC) that includes on-board T/H, voltage references, and timing circuits. The AD9032 uses a subranging converter architecture to achieve sample rates from dc to 25.6 MSPS. Pack- aged in a single 40-pin hybrid, the AD9032 is pin-compatible with the AD9034, which operates at word rates up to 20 MSPS. This ECL-compatible ADC requires only +5 V and –5.2 V sup- plies, an analog input, and a stable ECL clock to obtain the best dynamic performance available in a 12-bit ADC. This kind of performance is achieved with advanced bipolar circuits, custom designed and manufactured by Analog Devices. The latest in monolithic track-and-hold technology ensures accurate sam- pling of high frequency analog inputs. Dynamic performance has been optimized to achieve SNR of 64 dB and a spurious-free dynamic range (SFDR) of 74 dB for analog bandwidths up to 12 MHz. All units are tested for dy- namic performance at a sample rate of 25.6 MSPS. The AD9032 is available in either a 40-pin ceramic DIP or leaded flatpack. The two versions operate over an industrial (–25 °C to +85°C) or military (–55°C to +125°C) temperature range. OBSOLETE |
