Product Details

The MAX4209 evaluation kit (EV kit) simplifies evaluation of the MAX4208 ultra-low offset/drift, fixed gain, precision instrumentation amplifier in a µMAX® package. The MAX4209 features high-impedance differential inputs optimized for small voltages (±100mV max) and provides rail-to-rail output. The MAX4209 EV kit circuit uses the 100V/V fixed-voltage-gain version of the MAX4209. The EV kit operates from a single-supply voltage between 2.85V and 5.5V, or dual supplies providing ±1.425V to ±2.75V.

The MAX4209 EV kit can also evaluate the 10V/V and 1000V/V fixed-gain versions of the MAX4209 amplifiers, as well as the MAX4208 adjustable-gain amplifier. The MAX4209 IC temperature range is -40°C to +125°C.

The MAX4208 EV kit, available separately, evaluates the MAX4208 adjustable-gain amplifier with external gain-setting resistors.

Note: To evaluate a MAX4208 IC featuring externally adjustable gain, order a MAX4208EVKIT+ or request a free sample of the MAX4208AUA+ IC along with the MAX4209EVKIT+. For the alternate-gain versions of the MAX4209 IC, see the Part Selection Table in the full data sheet for IC ordering information.
