WM2125

The WM2125 is a dual channel 10-bit 40MSPS ADC which consumes only 240mW from a single 3.3V supply. The device is optimised for communications applications that require close matching between channels and a wide input bandwidth.

Input signals are differential for improved noise performance. Both A and B input channels are sampled simultaneously and are processed through matched signal paths and 10-bit multistage pipeline ADC. A number of different input clock / output data formats are supported including 20-bits wide at the sampling rate or 10-bits wide at twice the sampling rate, with additional clock outputs supplied by the device to latch the output data.

System design and power requirements are further simplified by the provision of an on-chip precision voltage reference. Alternatively, external references can be used if higher precision references are required.
