applications

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

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.
