description
The TLC5510 and TLC5510A are CMOS, 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
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.
