TLC1541IN

The TLC1541IN is a CMOS Analog-to-digital Converter (ADC) built around a 10-bit switched-capacitor successive-approximation 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 2.1MHz system clock for the TLC1541 with a design that includes simultaneous read/write operation, allows high-speed data transfers and sample rates up to 32 258SPS. 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. The converter incorporated in the TLC1541 feature differential high-impedance reference inputs that facilitate ratiometric conversion, scaling and analog circuitry isolation from logic and supply noises.
