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 VDDA. Only external jumpers are required to implement this option and eliminates the

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.
