DESCRIPTION
The ADS7825 can acquire and convert 16 bits to
within
±2.0 LSB in 25s 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 ADS7825 is a
low-power 16-bit sampling A/D with a four channel
input multiplexer, S/H, clock, reference, and a
parallel/serial microprocessor interface. It can be con-
figured in a continuous conversion mode to sequen-
tially digitize all four channels. The 28-pin ADS7825
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.
