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.
