Frequently Asked Questions

What is the operating temperature range for different versions?

The ADC0800PD operates over 55°C to 125°C, while the ADC0800PCD operates over 0°C to 70°C.

What are the electrical specifications at room temperature (25°C)?

Typical leakage currents for logical '1' and '0' inputs at ambient conditions are 1 mA and V respectively, while output leakage is also typically 2 mA.

How fast can the ADC0800 perform conversions?

The typical conversion speed is up to 800 kHz when operating between 0°C and 70°C.
