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.
