description
The
analog-to-digital converters built around an 8-bit
switched capacitor successive-approximation
analog-to-digital converter. They are designed for
serial interface to a microprocessor or peripheral
via a 3-state output with up to four control inputs
including independent SYSTEM CLOCK, I/O
CLOCK, chip select (CS), and ADDRESS INPUT.
A 4-MHz system clock for the TLC545 and a
2.1-MHz system clock for the TLC546 with a
design that includes simultaneous read/write
operation allowing high-speed data transfers and
sample rates of up to 76,923 samples per second
for the TLC545, and 40,000 samples per second
for the TLC546.
TLC545
and
TLC546
are
CMOS
In addition to the high-speed converter and
versatile control logic, there is an on-chip
20-channel analog multiplexer that can be used to
sample any one of 19 inputs or an internal self-test
voltage, and a sample-and-hold that can operate
automatically or under microprocessor control.
The converters incorporated in the TLC545 and TLC546 feature differential high-impedance reference inputs
that facilitate ratiometric conversion, scaling, and analog circuitry isolation from logic and supply noises. A totally
switched capacitor design allows low-error (
±
0.5 LSB) conversion in 9
μ
s for the TLC545, and 17
μ
s for the
TLC546, over the full operating temperature range.
