TLC540 (LIFEBUY) 8-Bit, 75 kSPS ADC Serial-Out, On-Chip 12-Ch. Analog Mux, 11 Ch.

 

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 75,180 samples 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.

The converters incorporated in the TLC540 and TLC541 feature differential high-impedance reference inputs that facilitate ratiometric conversion, scaling, and analog circuitry isolation from logic and supply noises. A switched-capacitor design allows low-error (±0.5 LSB) conversion in 9 us for the TLC540 and 17 us for the TLC541 over the full operating temperature range.

The TLC540I and TLC541I are characterized for operation from \x9640°C to 85°C. The TLC541M is characterized for operation from \x9655°C to 125°C.
