Evaluates: MAX14611 MAX14611 Evaluation Kit General Description Features and Benefits The MAX14611 evaluation kit (EV kit) is a fully assem- Proven PCB Layout bled and tested circuit board that demonstrates the Decrease Evaluation Time functionality of the MAX14611 quad bidirectional low- Fully Assembled and Tested voltage logic-level translator in a 14-pin TDFN package. On-Board Adjustable Oscillators The highly configurable PCB enables direct evaluation Evaluate without External Function Generator of the IC through multiple jumper-selectable methods. Jumper-Selectable Open-Drain and Push-Pull Buffers Input power to the EV kit is provided by a Micro-USB, Enable Simple Evaluation in Either Operating Mode type-B connector, or by an external 5V power supply. On-board LDO regulators provide the appropriate voltage for each component, and potentiometers allow the user to independently adjust the power supply for either side of Ordering Information appears at end of data sheet. the level translator. 3) Connect the DVM between GND (TP1) and VCC Quick Start (TP27). Adjust the 1st potentiometer (POT1) until Required Equipment the desired voltage for VCC appears on the DVM by MAX14611 EV kit turning the screw on the potentiometer to the right or to the left. Digital voltmeter (DVM) 4) Connect the DVM between GND (TP1) and VL (TP28). USB power source or another 5V external power supply Adjust the 2nd potentiometer (POT2) until the desired Oscilloscope and at least one scope probe voltage for VL appears on the DVM by turning the screw on the potentiometer to the right or to the left. Procedure Note that VL should be lower than VCC. The EV kit is fully assembled and tested. Follow the steps below to verify board operation and begin evaluation: 5) Connect the jumpers in the desired configuration based on the descriptions listed in Table 1. 1) If using a USB bus to power the board, connect the included Micro-USB cable between the Micro-USB, 6) After implementing the desired configuration, type-B connector (J1) and the USB power source, connect the oscilloscope probe to the output evaluated such as a computer or dedicated USB charging port, to observe the translated voltage of the input signal. and install a shunt on jumper JP22 shorting pins 1-2. 2) If using an external power source to power the board, connect the external power supply at the VEXT test point (TP2) and install a shunt on jumper JU22 shorting pins 2-3. 19-6808 Rev 0 9/13Evaluates: MAX14611 MAX14611 Evaluation Kit Table 1.
