Datasheet AD9218-EP (Analog Devices)

10-Bit, 105 MSPS, 3 V, Dual ADC Enhanced Product AD9218-EP FEATURES GENERAL DESCRIPTION Dual, 10-bit, 105 MSPS ADC
The AD9218-EP is a dual, 10-bit, monolithic sampling analog-
Low power: 275 mW at 105 MSPS per channel
to-digital converter (ADC) with on-chip track-and-hold
On-chip reference and track-and-hold
circuits. The product is low cost, low power, and is small and
300 MHz analog bandwidth for each channel
easy to use. The AD9218-EP operates at a 105 MSPS conversion
SNR = 54 dB at 51 MHz, encode = 105 MSPS
rate with dynamic performance over its full operating range.
1 V p-p analog input range for each channel
Each channel can be operated independently.
3.0 V single-supply operation (2.7 V to 3.6 V)
The ADC requires only a single 3.0 V (2.7 V to 3.6 V) power
Power-down mode for single-channel operation
supply and a clock for full operation. No external reference or
Twos complement or offset binary output mode
driver components are required for many applications. The
Output data alignment mode
digital outputs are transistor-to-transistor logic (TTL)/
