The AD9214 is a 10-bit monolithic sampling analog-to-digital High Performance—Outstanding ac performance from 65 MSPS converter (ADC) with an on-chip track-and-hold circuit, and to 105 MSPS. SNR greater than 55 dB typical and as high is optimized for low cost, low power, small size, and ease of use. as 58 dB. The product operates up to 105 MSPS conversion rate with Low Power—The AD9214 at 285 mW consumes a fraction of outstanding dynamic performance over its full operating range. the power available in existing high-speed monolithic solutions. The ADC requires only a single 3.3 V (2.7 V to 3.6 V) power In sleep mode, power is reduced to 30 mW. supply and an encode clock for full performance operation. No Single Supply—The AD9214 uses a single 3 V supply, simplify- external reference or driver components are required for many ing system power supply design. It also features a separate digital applications. The digital outputs are TTL/CMOS compatible output driver supply line to accommodate 2.5 V logic families. and a separate output power supply pin supports interfacing with 3.3 V or 2.5 V logic. Small Package—The AD9214 is packaged in a small 28-lead surface-mount plastic package (28-SSOP). The clock input is TTL/CMOS compatible. In the power-down state, the power is reduced to 30 mW. A gain option allows support for either 1 V p-p or 2 V p-p analog signal input swing. Fabricated on an advanced CMOS process, the AD9214 is available in a 28-lead surface-mount plastic package (28-SSOP) specified over the industrial temperature range (–40°C to +85°C). REV.
