DESCRIPTION
The TLC1542C, TLC1542I, TLC1542M, TLC1542Q,
TLC1543C, TLC1543I, and TLC1543Q are CMOS
10-bit switched-capacitor successive-approximation
analog-to-digital converters. These devices have
three inputs and a 3-state output [chip select (CS),
input-output clock (I/O CLOCK), address input
(ADDRESS), and data output (DATA OUT)] that
provide a direct 4-wire interface to the serial port of a
host processor. These devices allow high-speed data
transfers from the host.
In addition to a high-speed A/D converter and
versatile control capability, these devices have an
on-chip 14-channel multiplexer that can select any
one of 11 analog inputs or any one of three internal
self-test voltages. The sample-and-hold function is
automatic. At the end of A/D conversion, the
end-of-conversion (EOC) output goes high to
indicate that conversion is complete. The converter
incorporated in the devices features differential
high-impedance reference inputs that facilitate
ratiometric conversion, scaling, and isolation of
analog circuitry from logic and supply noise. A
switched-capacitor
design
allows
low-error
conversion over the full operating free-air
temperature range.
