No Preview Available ! a Monolithic 8-Bit Video A/D Converter AD9048 FEATURES 35 MSPS Encode Rate 16 pF Input Capacitance 550 mW Power Dissipation Industry-Standard Pinouts MIL-STD-883 Compliant Versions Available APPLICATIONS Professional Video Systems Special Effects Generators Electro-Optics Digital Radio Electronic Warfare (ECM, ECCM, ESM) GENERAL DESCRIPTION The AD9048 is an 8-bit, 35 MSPS flash converter, made on a high speed bipolar process, which is an alternate source for the TDC1048 unit, and offers enhancements over its predecessor. 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.
