MAX4209 Features
* Ultra-Low Input Offset Voltage ±20µV (max) at +25°C
* ±0.25% (max) Gain Error
* Low 0.2µV/°C Offset Voltage Drift
* 1pA CMOS Input Bias Current

MAX4209 Applications
* In both devices, REFIN/MODE is an input to a precision unity-gain buffer, which sets the REF voltage to level-shift the output. The internal REF buffer allows the reference to be set by a simple resistive divider or an ADC reference without any loading error. The MAX4208/MAX4209 operate with a 2.85
