4 Channel, 16-Bit Sampling CMOS A/D Converter  
FEATURES  
DESCRIPTION  
25µs max SAMPLING AND CONVERSION  
SINGLE +5V SUPPLY OPERATION  
PIN-COMPATIBLE WITH 12-BIT ADS7824  
PARALLEL AND SERIAL DATA OUTPUT  
28-PIN 0.3" PLASTIC DIP AND SOIC  
±2.0 LSB max INL  
The ADS7825 can acquire and convert 16 bits to  
within ±2.0 LSB in 25µs 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.
