The ADS7824P is a 4-channel sampling CMOS Analog-to-digital Converter (ADC) can acquire and convert 12-bit to within ±0.5LSB in 25μs maximum while consuming only 50mW max. Laser-trimmed scaling resistors provide the standard industrial ±10V input range and channel-to-channel matching of ±0.1%. The ADC is a low-power 12-bit sampling A/D with a four channel input multiplexer, S/H, clock, reference and a parallel/serial microprocessor interface. It can be configured in a continuous conversion mode to sequentially digitize all four channels.
