description

The TLV1543M is an Advanced LinEPIC^TM 10-bit, switched-capacitor, successive-approximation, analog-to-digital converter. The device has three inputs and a 3-state output [chip select (CS\), input-output clock (I/O CLOCK), address input (ADDRESS), and data output (DATA OUT)] that provide a direct four-wire interface to the serial port of a host processor. The device allows high-speed data transfers from the host.

In addition to a high-speed A/D converter and versatile control capability, the TLV1543M has an on-chip 14-channel multiplexer that can select any one of 11 analog inputs or any one of three internal self-test voltages. The sample-and-hold function is automatic. At the end of A/D 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 free-air temperature range.

The TLV1543M is characterized for operation over the full military temperature range of -55°C to 125°C.
