description
The TLC540 and TLC541 are CMOS A / D
converters built around an 8-bit switched-
capacitor
successive-approximation
A/D
converters. 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 TLC540 and a 2.1-MHz
system clock for the TLC541 with a design that
includes simultaneous read/write operation allow high-speed data transfers and sample rates of up to
75,180samples per second for the TLC540 and 40,000 samples per second for the TLC541. In addition to the
high-speed converter and versatile control logic, there is an on-chip 12-channel analog multiplexer that can be
used to sample any one of 11 inputs or an internal self-test voltage, and a sample-and-hold that can operate
automatically or under microprocessor control.
