TLC540I, TLC541I
8-BIT ANALOG-TO-DIGITAL CONVERTERS
WITH SERIAL CONTROL AND 11 INPUTS
SLAS065B – OCTOBER 1983 – REVISED JUNE 2001

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
The converters incorporated in the TLC540 and TLC541 feature differential high-impedance reference inputs
that facilitate ratiometric conversion, scaling, and analog circuitry isolation from logic and supply noises. A
switched-capacitor design allows low-error (
±0.5 LSB) conversion in 9 s for the TLC540 and 17 s for the
TLC541 over the full operating temperature range.
The TLC540I and TLC541I are characterized for operation from – 40
°C to 85°C.The TLC541M is characterized
for operation from – 55
°C to 125°C.
