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, 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 preclude 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 in-
puts 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.
