Frequently Asked Questions
What is the maximum operating temperature range?
The device operates over an industrial temperature range of -40 °C to +85 °C.
How much does the converter consume during normal operation?
Typical power consumption is 1.4 Watts from a single 1.9 Volt supply.
What are the main features of this 8-bit A/D Converter?
It features an internal Sample-and-Hold amplifier, guaranteed no missing codes, and has fully differential comparator design.
Under what conditions can I put it into a low power state?
Setting the PD (Power Down) pin high puts the converter into an inactive power down state, consuming typically less than 5 mW.
