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.

PRODUCTION DATA information is current as of publication date.
