DESCRIPTION

The ADS7824 can acquire and convert 12 bits to within ±0.5 LSB in 25µs max while consuming only 50mW max.

Laser-trimmed scaling resistors provide the standard industrial ±10V input range and channelto-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.
