The ADS7824 can acquire and convert 12 bits to within ±0.5 LSB in 25us max 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 ADS7824 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. The 28-pin ADS7824 is available in a plastic 0.3" DIP and in a SOIC, both fully specified for operation over the industrial –40°C to +85°C range.
