† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to the GND terminal with REF and GND wired together (unless otherwise noted).


Description

The TLV2543C and TLV2543I are 12-bit, switched-capacitor, successive-approximation, analog-to-digital converters (ADCs). Each TLV2543C and TLV2543I  device has three control inputs [chip select (CS), the input-output clock (I/O CLOCK), and the address input (DATA INPUT)] and is designed for communication with the serial port of a host processor or peripheral through a serial 3-state output. The device allows high-speed data transfers from the host.

In addition to the high-speed converter and versatile control capability, the TLV2543C and TLV2543I  have an on-chip 14-channel multiplexer that can select any one of 11 inputs or any one of three internal self-test voltages. The sample-and-hold function is automatic. At the end of conversion, the end-of-conversion (EOC) output goes high to indicate that conversion is complete. The converter incorporated in the device features differential high-impedance reference inputs that facilitate ratiometric conversion, scaling, and isolation of analog circuitry from logic and supply noise. A switched-capacitor design allows low-error conversion over the full operating temperature range.The TLV2543 is available in the DW, DB, and N packages. The TLV2543C is characterized for operation from 0°C to 70°C, and the TLV2543I is characterized for operation from 40°C to 85°C.
