 软件简介 |
The TLC545 and TLC546 are CMOS
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.
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 ms for the TLC545, and 17 ms for the
TLC546, over the full operating temperature range.
