EATURES q 100k Hz SAMPLING RATE q 1500Vrms ISOLATION CONTINUOUS q 10µS CONVERSION TIME q 16-BIT SERIAL OUTPUT q SINGLE +5V SUPPLY q 28-PIN 0.6" PLASTIC DIP DESCRIPTION The ISO809 is a low-power isolated sampling ADC using state-of-the-art CMOS structures and high voltage capacitors. The ISO809 contains a plete 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.
