Co., Ltd. 770-436-1300 TDK Corp. 847-803-6100 TOKO America, Inc. 847-297-0070 Note Indicate that you are using the MAX4990 when contacting these component suppliers. Quick Start Recommended Equipment Before beginning, the following equipment is needed • MAX4990 EV kit • A user-supplied electroluminescent EL lamp • 5V DC power supply • Oscilloscope to monitor VA and VB Procedure The MAX4990 EV kit is fully assembled and tested. Follow the steps below to verify board operation: 1 Verify that all jumpers are in their default positions, as shown in Table 2 Connect the VA and VB alligator clip leads to the EL lamp. Note Under some conditions, the VA/VB output may be as high as 250VP-P. 3 Connect the oscilloscope to VA and VB. With math function, monitor VA-VB waveform. 4 Connect the 5V DC power supply between the VDD and GND pins. 5 Switch on the 5V power supply. Verify that the EL lamp illuminates.
