The reference is also differential, with the posi- tive reference (RFPF) typically connected to +4.096V Three-State, Two’s Complement Output Data and the negative reference (RFNF) connected to ana- log ground. Additional sensing pins (RFPS, RFNS) are provided to compensate for any resistive-divider action

Frequently Asked Questions
What resolution and conversion rate does the MAX1205 offer?
It is a 14-bit ADC capable of conversion rates up to 1Msps.
Are there options for different operating temperatures?
Yes, it is available in commercial (0°C to +70°C) and extended (-40°C to +85°C) ranges.
How does the user need to decouple the power inputs?
The AV input should be decoupled with parallel 0.1µF and 0.001µF ceramic-chip capacitors.
Is there an upgrade option for a higher data rate?
For rates higher than 1Msps, the MAX1201 is mentioned as a pin-compatible alternative.
