MAX4209HAUA+

Maxim Integrated · Pre-ordered Chips · MSOP-8

MAX4209HAUA+ from Maxim Integrated, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REFIN/MODE input Trimode input: connect to VDD for shutdown (about 1.4µA), to an external reference or resistive divider between VSS + 0.2V and VDD - 1.3V to buffer it onto REF, or to VSS to put the internal REF buffer output in high impedance for direct drive of REF.
2 IN- input Negative differential input; the maximum recommended differential input voltage is ±100mV, and linearity and accuracy degrade above that level.
3 IN+ input Positive differential input; the maximum recommended differential input voltage is ±100mV, and linearity and accuracy degrade above that level.
4 VSS power_in Negative supply input; bypass to ground with a 0.1µF capacitor or connect to ground for single-supply operation (2.85V to 5.5V total supply).
5 REF input Output reference level that sets the OUT voltage for zero differential input; it is set by the internal buffer when REFIN/MODE is between VSS + 0.2V and VDD - 1.3V, and must be driven directly by a low-impedance reference only when REFIN/MODE is at VSS.
6 FB input Feedback input: on the MAX4208 connect to the center tap of an OUT-to-REF resistive divider to set gain, while on the MAX4209 it is internally connected to the gain-setting resistors; an optional CFB from OUT to FB (1nF to 10nF recommended) reduces autozero noise.
7 OUT output Amplifier output with rail-to-rail capability; in unipolar operation it can only swing to within 40mV of ground (VSS), and the device drives capacitive loads up to 200pF.
8 VDD power_in Positive supply input; bypass to ground with a 0.1µF capacitor (single-supply range 2.85V to 5.5V).
