RANGE IC PACKAGE MAX4201EVKIT -40°C to +85°C 8 SO _________________________Quick Start The MAX4201 EV kit is fully assembled and tested. Follow these steps to verify board operation. Do not turn on the power supply until all connections are completed. 1) The circuit requires supply voltages of ±4.0V to ±5.5V. For evaluation purposes, connect a +5V supply to the pad labeled VCC and a -5V supply to the pad labeled VEE. Connect the power-supply grounds to the pad marked GND. 2) Connect the output marked OUT to an oscilloscope through a terminated 50Ω cable. 3) Turn on the power supply. Apply a signal of ±3.3V maximum to the SMA connector marked IN+. 4) Verify the output signal on the oscilloscope. (Note: When using a 50Ω terminated oscilloscope input, the output amplitude observed on the oscilloscope will be half that on the input. This is due to the voltage divider formed by the internal 50Ω back-terminating resistor and the oscilloscope input termination impedance.) ________________________________________________________________ Maxim Integrated Products 1 For free samples & the latest literature: http://www.maxim-ic.com, or phone 1-800-998-8800.

Evaluates: MAX4200/MAX4201/MAX4202 ________________General Description The MAX4201 evaluation kit (EV kit) simplifies evaluation of the MAX4201 ultra-high-speed, low-power, lownoise, open-loop buffer. The EV kit circuit demonstrates the MAX4201 in the noninverting unity-gain configuration. RF-style connectors (SMA) and 50Ω terminating resistors are included for test equipment compatibility. This EV kit can also be used to evaluate the MAX4200 and MAX4202 (contact Maxim for free samples). Note that the MAX4201 has an internal 50Ω output termination resistor, and the MAX4202 has an internal 75Ω output termination resistor, while the MAX4200 has no internal output termination resistor (refer to the MAX4200–MAX4205 data sheet for more information). Evaluates: MAX4200/MAX4201/MAX4202 MAX4201 Evaluation Kit _______________Detailed Description bypass capacitors (C2, C4) have been placed as close to the MAX4201 supply pins as possible. A continuous ground plane has been maintained under the IC to reduce inductance to the signal return path. Layout Considerations The MAX4201 EV kit layout has been optimized for high-speed signals and low distortion with careful attention given to grounding, power-supply bypassing, and signal-path layout. The small, surface-mount, ceramic 1 When using the MAX4200, replace R2 with an appropriate terminating resistor. N.C. N.C. 8 U1 2 N.C.
