The TLC1541 is a CMOS A/D converter built around a 10-bit switched-capacitor successiveapproximation A/D converter. The device is 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 TLC1541, with a design that includes simultaneous read/write operation, allows highspeed 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-andhold function that operates automatically. |
