description
TheTLC5510andTLC5510AareCMOS, 8-bit, 20
MSPS analog-to-digital converters (ADCs) that
utilize a semiflash architecture. The TLC5510 and
TLC5510A operate with a single 5-V supply and
typically consume only 130 mW of power.
Included is an internal sample-and-hold circuit,
parallel outputs with high-impedance mode, and
internal reference resistors.

The semiflash architecture reduces power
consumption and die size compared to flash
converters. By implementing the conversion in a
2-step process, the number of comparators is
significantly reduced. The latency of the data
output valid is 2.5 clocks.

The TLC5510 uses the three internal reference
resistors to create a standard, 2-V, full-scale
conversion range using V
. Only external jumpers are required to implement this option and eliminates the
DDA
need for external reference resistors. The TLC5510A uses only the center internal resistor section with an
externally applied 4-V reference such that a 4-V input signal can be used. Differential linearity is 0.5 LSB at 25°C
and a maximum of 0.75 LSB over the full operating temperature range. Typical dynamic specifications include
a differential gain of 1% and differential phase of 0.7 degrees.
The TLC5510 and TLC5510A are characterized for operation from –20°C to 75°C.
