XL2543,XD2543N,XL2543-SS Product datasheet
■The XL2543 and XD2543 are 12-bit, switched capacitor, successive approximation, analog to digital converters. Each device, with three control inputs [chip select (CS), the input-output clock, and the address input (DATA INPUT)], 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 device has 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.
