SMA Connectors to Connect to External Equipment The functionality and performance of the QSOP versions Guaranteed Up to 5kV Isolation RMS (MAX1413x) can be tested indirectly by using this EVkit (for the Wide-Body SOIC Version) populated with any of the equivalent narrow or wide Also Evaluates the 2.75KV Versions. SOIC (MAX1493x) devices. The functionality and electri- RMS cal performance of the QSOP versions are identical to their corresponding SOIC versions. The EV kit features two independent isolated power supplies independently adjustable to +5V. Ordering Information appears at end of data sheet.

MAX1493X device separated sampled Two 5V DC power supplies or USB cables with a External Power Supplies micro-B connector Power on the MAX1493X EV kit is derived from two Signal/function generator +5V sources. Connect external supplies to the +5V and Oscilloscope GNDA test points, or connect a micro-B USB cable to the Procedure on-board PA/PB connectors to provide the 5V. Both options have a reverse-current protection diode. The MAX1493X EV kit has everything except the DUT installed. The user can install the desired flavor of The MAX1493X level-shifts the data and control signals, the MAX1493X family of unidirectional isolators. Once transmitting them across the isolation barrier. Each supply installed, follow the steps below to verify board operation: is set independently and can be present over the entire specified range of the device, regardless of the level or 1) Connect the DC power supplies between the presence of the other supply. MAX1493X EV kits VDDA/VDDB and GNDA/GNDB test points. Figure 1 is a simplified schematic showing the connections 2) Turn on the DC power supplies and set to 5V, then for evaluating the MAX1493X in a simple microprocessor enable the power-supply output. interface. The MAX1493X level-shifts the signals and Note: It is also possible to power the MAX1493X EV transmits them across the isolation barrier. kit with standard USB ports. To do so, connect the micro-B-end of the USB cables into PA/PB on the board. Connect the A-end of the USB cable into the USB ports. Please ensure that only one type of supply is used on either side (USB or DC power supply). 3) Connect any signal to the SMA connectors or test points and observe the isolated signal on the other side using an oscilloscope.
