1 / 19 page TLC540I, TLC541I 8-BIT ANALOG-TO-DIGITAL CONVERTERS WITH SERIAL CONTROL AND 11 INPUTS SLAS065B – OCTOBER 1983 – REVISED JUNE 2001 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 8-Bit Resolution A/D Converter D Microprocessor Peripheral or Stand-Alone Operation D On-Chip 12-Channel Analog Multiplexer D Built-In Self-Test Mode D Software-Controllable Sample and Hold D Total Unadjusted Error ... ±0.5 LSB Max D TLC541 Is Direct Replacement for Motorola MC145040 and National Semiconductor ADC0811. TLC540 Is Capable of Higher Speed D Pinout and Control Signals Compatible With TLC1540 Family of 10-Bit A/D Converters D CMOS Technology PARAMETER TLC540 TLC541 Channel Acquisition Sample Time Conversion Time (Max) Samples per Second (Max) Power Dissipation (Max) 2 µs 9 µs 75 x 103 12.5 mW 3.6 µs 17 µs 40 x 103 12.5 mW 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.
