ADC1205 ADC1225 12-Bit Plus Sign mP patible A D Converters
General Description
The ADC1205 and ADC1225 are CMOS 12-bit plus sign successive approximation A D converters The 24-pin ADC1205 outputs the 13-bit data result in two 8-bit bytes formatted high-byte first with sign extended The 28-pin ADC1225 outputs a 13-bit word in parallel for direct interface to a 16-bit data bus Negative numbers are represented in 2’s plement data format All digital signals are fully TTL and MOS patible A unipolar input (0V to 5V) can be acmodated with a single 5V supply while a bipolar input (b5V to a 5V) requires the...
