DESCRIPTION
The TLV5580 is an 8-bit 80 MSPS high-speed A/D
converter. It converts the analog input signal into
8-bit binary-coded digital words up to a sampling
rate of 80 MHz. All digital inputs and outputs are
3.3 V TTL/CMOS-compatible.
The device consumes very little power due to the
3.3 V supply and an innovative single-pipeline
architecture implemented in a CMOS process.
The user obtains maximum flexibility by setting
both bottom and top voltage references from
user-supplied voltages. If no external references
are available, on-chip references are available for

internal and external use. The full-scale range is
1 Vpp up to 1.6 Vpp, depending on the analog
supply voltage. If external references are
available, the internal references can be disabled
independently from the rest of the chip, resulting
in an even greater power saving.
While usable in a wide variety of applications, the
device is specifically suited for the digitizing of
high-speed graphics and for interfacing to LCD
panels or LCD/DMD projection modules . Other
applications include DVD read channel
digitization,
medical
imaging
and
communications. This device is suitable for IF
sampling of communication systems using
sub-Nyquist sampling methods because of its
high analog input bandwidth.
