Content for TLC1540

The TLC1540 and TLC1541 are CMOS A/D converters built around a 10-bit switched-capacitor successive-approximation A/D converter. They are designed for serial interface to a microprocessor or peripheral using a 3-state output with up to four control inputs (including independent SYSTEM CLOCK, I/O CLOCK, chip select (CS), and ADDRESS INPUT). A 2.1-MHz system clock for the TLC1540 and TLC1541, with a design that includes simultaneous read/write operation, allows high-speed data transfers and sample rates up to 32 258 samples per second. 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 function that operates automatically.
