These outputs can be set to either 1.8 V CMOS or LVDS. The ADC output data can be routed directly to the two external 16-bit output ports or multiplexed on a single 16-bit bus. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converters to maintain excellent performance. Each ADC features wide bandwidth, differential sample-and-hold analog input amplifiers, and shared integrated voltage reference, which eases design considerations. However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties that may result from its use. A Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable. The dual ADC core features a multistage, differential pipelined architecture with integrated output error correction logic. 1.8 V Analog-to-Digital Converter Data Sheet AD9656 Rev.

A 1.8 V, 0.5 A supply is needed for 1.8 V_AVDD, a 2.5 V, 0.5 A supply is needed for DRVDD, a 2.5 V 0.5 A supply is needed for V-DIG, and a 3.3 V, 0.5 A supply is needed for 3P3V. Use P202 and P201 to connect a different supply for each section. This enables the user to bias each section of the board individually. To do this, remove the all the jumpers listed above (and in Table 1) to disconnect the outputs from the on-board LDOs. The evaluation board can be powered in a nondefault condition using external bench power supplies. The 6 V supply is fused and conditioned on the PCB before connecting to the low dropout linear regulators that supply the proper bias to each of the various sections on the board. The output from the supply is provided through a 2.1 mm inner diameter jack that connects to the printed circuit board (PCB) at P200. Connect the supply to a 100 V ac to 240 V ac, 47 Hz to 63 Hz wall outlet. This evaluation board comes with a wall-mountable switching power supply that provides a 6 V, 2 A maximum output.
