DESCRIPTION

The ADS7825 can acquire and convert 16 bits to

within ±2.0 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 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 configured

in a continuous conversion mode to sequentially

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.
