Overview
® 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.
