NAME
FUNCTION
1
REFIN/MODE
Reference/Shutdown Mode Input. Trimode function is as follows:
Connect to VDD to put the device in shutdown mode.
Connect to an external reference (between VSS + 0.2V and VDD - 1.3V) to buffer the voltage at
REFIN/MODE. Using the REF buffer allows the use of a simple resistor-divider or high-impedance
external reference to set the OUT level at 0mV IN with minimum error.
Connect to VSS to force the internal buffer output into a high-impedance state to allow external direct
drive of REF.
2
IN-
Negative Differential Input
3
IN+
Positive Differential Input
4VSS
Negative Supply Input. Bypass VSS to ground with a 0.1F capacitor or connect to ground for
single-supply operation.
5
REF
Output Reference Level. REF sets the OUT voltage for zero differential input. The internal buffer
sets the voltage at REF when the voltage at REFIN/MODE is between VSS + 0.2V and VDD - 1.3V.
6FB
Feedback Input. Connect FB to the center tap of an external resistive divider from OUT to REF to
set the gain for the MAX4208. MAX4209 FB is internally connected to gain-setting resistors. Connect
an optional capacitor, CFB, from OUT to FB to reduce autozero noise.
7
OUT
Amplifier Output
8VDD
Positive Supply Input. Bypass VDD to ground with a 0.1F capacitor.

Typical Operating Characteristics (continued)
(VDD = 5V, VSS = 0V, VCM = VREF = VDD/2, VREFIN/MODE = VSS, RL = 100k
Ω to VDD/2, VDIFF = (VIN+ - VIN-) = 0V, MAX4208 set for
G = 100V/V (R1 = 1k
Ω, R2 = 99kΩ), TA = +25°C, unless otherwise noted.)
