ISO808

® ISO8 08 ISO808 Isolated 12-Bit Sampling ANALOG-TO-DIGITAL CONVERTER FEATURES q 100kHz SAMPLING RATE q 1500Vrms ISOLATION CONTINUOUS q 10µS CONVERSION TIME q 12-BIT SERIAL OUTPUT q SINGLE +5V SUPPLY q 28-PIN 0.6" PLASTIC DIP DESCRIPTION The ISO808 is a low-power isolated sampling ADC using state-of-the-art CMOS structures and high voltage capacitors. The ISO808 contains a complete 12-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 20kΩ R1IN 10kΩ R2IN 5kΩ R3IN CAP Internal +2.5V Ref 4kΩ REF 20kΩ Clock BUSY 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.
