AD9648 is a 14-bit, 125MSPS/105MSPS, 1.8V dual analog-to-digital converter with 1.8V CMOS or LVDS outputs. AD9648 has low power consumption (78 mW/channel ADC core @ 125 MSPS), differential analog input bandwidth up to 650 MHz, IF sampling frequencies up to 200 MHz. AD9648 also has a voltage reference and sample-and-hold circuit, DNL accuracy of ±0.35 LSB.
The AD9648 is a monolithic, dual‑channel, 1.8 V supply, 14‑bit analog‑to‑digital converter. It offers a high‑performance sample‑and‑hold circuit, on‑chip voltage reference, and programmable clock and data alignment. Output formats include offset binary, gray code, or two's complement, and the device can drive either 1.8 V CMOS or LVDS logic families.
The converter is packaged in a 64‑lead RoHS‑compliant LFCSP and operates over an industrial temperature range (‑40 °C to +85 °C). It includes built‑in self‑test features, programmable digital test pattern generation, and power‑down modes for low‑power applications.
