Output fre- quency and duty cycle are easily adjusted with on- board potentiometers. Removable jumpers select sine, square, or triangle waveforms, or fix the duty cycle at 50%. The output is buffered with a MAX442 amplifier capable of driving a 50 Ω coaxial cable. The MAX038 EV kit is fully assembled and tested. ___________________________Features o 325kHz to 10MHz Operation o Adjustable Duty Cycle o 2.5V Reference Output o TTL-Compatible SYNC Output o Fully Assembled and Tested ____________________Component List _________________________Quick Start The MAX038 EV kit is a fully assembled and tested board. Follow these steps to verify board operation. Do not turn on the power supply until all connections are completed. 1) Connect a +5V supply to the pad marked +5V. Connect a -5V supply to the pad marked -5V. Connect ground(s) to the GND pad. 2) Connect an oscilloscope to the BNC jack marked OUTPUT through a terminated 50 Ω cable. The MAX038 output prior to the amplifier stage may also be monitored using an oscilloscope probe at the OUT pad. 3) Place the shunt across pins 2 and 3 of JU4 for 50% duty cycle. Place the shunt across pins 1 and 2 of ______________Ordering Information ______________________________EV Kit DESIGNATION QTY DESCRIPTION U1 1 MAX038CPP U2 1 MAX442CPA C1 1 82pF capacitor C2, C3, C5, C7, C9, C10, C11, C12 8 0.1µF capacitors C4, C6, C8 3 4.7µF capacitors R1, R2 2 20k Ω potentiometers R3 1 50k Ω potentiometer R4, R5 2 10k Ω, 5% resistors R6 1 51 Ω, 5% resistor R7, R8 2 270 Ω, 5% resistors R9, R10, R11 3 0 Ω resistors R12 1 3.3k Ω, 5% resistor JU1, JU2, JU5 3 2-pin headers JU3, JU4 2 3-pin headers None 5 Shunts J1 1 BNC jack PART MAX038EVKIT-DIP 0°C to +70°C TEMP.
