The ISO807 contains a complete 16-bit capacitor based SAR, ADC with S/H, clock, reference, µP interface, serial out and galvanic isolation. Laser-trimmed scaling resistors provide standard industrial input ranges including ±10V, ±5V, 0-5V, 0-4V. They are available in 28-pin 0.6" wide plastic DIP and are specified over the industrial temperature range of –40°C to +85°C. www.DataSheet.net/ APPLICATIONS q INDUSTRIAL PROCESS CONTROL q PC-BASED DATA ACQUISITION TEST EQUIPMENT Isolation Barrier Successive Approximation Register and Control Logic R/C 40kΩ R1IN Clock BUSY 10kΩ R2IN CAP Internal +2.5V Ref 6kΩ REF 40kΩ Serial Data Out Data Clock Serial Data SB/BTC International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.
