10-BIT ANALOG-TO-DIGITAL CONVERTERS
WITH SERIAL CONTROL AND 11 ANALOG INPUTS
10-Bit Resolution A/D Converter
11 Analog Input Channels
Three Built-In Self-Test Modes
Inherent Sample-and-Hold Function
Total Unadjusted Error: ±1LSB Max
On-Chip System Clock
End-of-Conversion (EOC) Output
Terminal Compatible With TLC542
CMOS Technology
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.
