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.
