Lower power dissipation makes the AD9048 attractive for a variety of system designs. Because of its wide bandwidth, it is an ideal choice for real-time conversion of video signals. Input bandwidth is flat with no missing codes. Clocked latching comparators, encoding logic, and output buffer registers operating at minimum rates of 35 MSPS pre- clude a need for a sample-and-hold (S/H) or track-and-hold (T/H) in most system designs using the AD9048. All digital control inputs and outputs are TTL compatible. Devices operating over two ambient temperature ranges and with two grades of linearity are available. Linearities of either 0.5 LSB or 0.75 LSB can be ordered for a commercial range of 0 °C to 70°C or extended case temperatures of –55°C to +125°C. Commercial versions are packaged in 28-lead DIPs; extended temperature versions are available in ceramic DIP and ceramic LCC packages. Both commercial units and MIL-STD-883 units are standard products. The AD9048 A/D converter is available in versions compliant with MIL-STD-883. Refer to the Analog Devices Military Prod- ucts Databook or current AD9048/883B data sheet for detailed specifications.
