Product Summary
The ADS7825U is a 4 Channel, 16-Bit Sampling CMOS A/D Converter. The ADS7825U 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 ADS7825U 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 ADS7825U is available in a plastic 0.3inch DIP and in a SOIC, both fully specified for operation over the industrial –40℃ to +85℃ range.
