DESCRIPTION
The ADS7824 can acquire and convert 12 bits to
within ±0.5 LSB in 25ms 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.
