Beschrijving

Description:

DS1220 is an accurate 24-bit analog digital converter (ADC) that offers many integrated features to reduce system costs and the number of components for small sensor signals. The part consists of a flexible input multiplexer (MUX), a low-noise amplifier with programmable gain (PGA), two programmable deployment current sources, a voltage reference, an oscillator, a low-side switch, and an accurate temperature sensor to implement two differential or four separate signals – closed inputs.

Features:

• Low power consumption: only 120 μA in working cycle mode (typical)
• Power Range: 3 V ~ 5 V.
• Up to 20 effective resolutions
• Two differential or four single-end inputs
• Dual tuned programmable power source: 10 μA to 1.5 mA.
• Internal 2.048V reference: 5 ppm/°C (typical) drift
• Internal oscillator with 2% precision.
• Internal temperature sensor: 0.5℃(typical) accuracy
• SPI compatible interface (mode 1)
• Operating temperature: -25 to +85 °C.
• Operating humidity: 5% ~ 95% relative humidity.

Usage:

• Temperature Sensor Measurement
• Bridge sensor measurement
• Portable instrument.
• Factory automation and process control
