TLC549I - 8-BIT ANALOG-TO-DIGITAL CONVERTERS

Download the TLC549I datasheet PDF. This datasheet also covers the TLC548C variant, as both devices belong to the same 8-bit analog-to-digital converters family and are provided as variant models within a single manufacturer datasheet.

General Description

The TLC548 and TLC549 are CMOS analog-to-digital converter (ADC) integrated circuits built around an 8-bit switched-capacitor successive-approximation ADC.

These devices are designed for serial interface with a microprocessor or peripheral through a 3-state data output and an analog input.

Key Features

  • include versatile control logic, an on-chip sample-and-hold circuit that can operate automatically or under microprocessor control, and a high-speed converter with differential high-impedance reference voltage inputs that ease ratiometric conversion, scaling, and circuit isolation from logic and supply noises. Design of the totally switched-capacitor successive-approximation converter circuit allows conversion with a maximum total error of ± 0.5 least significant bit (LSB) in less than 17 µs. Th.
