–75 dBc crosstalk between channels The AD9218-EP is a dual, 10-bit, monolithic sampling analogto-digital converter (ADC) with on-chip track-and-hold
circuits. The product is low cost, low power, and is small and
easy to use. The AD9218-EP operates at a 105 MSPS conversion
rate with dynamic performance over its full operating range.
Each channel can be operated independently.
The ADC requires only a single 3.0 V (2.7 V to 3.6 V) power
supply and a clock for full operation. No external reference or
driver components are required for many applications. The
digital outputs are transistor-to-transistor logic (TTL)/
complementary metal-oxide semiconductor (CMOS)
compatible, and a separate output power supply pin supports …
