19-6277 Rev 0 4/12 MAX4936A Evaluation Kit Evaluates: MAX4936A/MAX4937A General Description Features The MAX4936A evaluation kit (EV kit) provides a proven S SMA Connectors for Transmitter/Receiver Signals design to evaluate the MAX4936A high-voltage transmit/ S Test Points for Monitoring Transmitter/Receiver receive (T/R) switch used in ultrasound applications. Signals The EV kit provides SMA connectors for interfacing to S Independent Enable Control for Two Banks of the application circuit transmitters and receivers outputs Four Channels and inputs, respectively. Test points are provided for S RoHS Compliant monitoring the channels transmit/receive signals. The EV S Proven PCB Layout kit circuit also provides various PCB pads for configuring the load at the transmitters outputs and receivers inputs. S Fully Assembled and Tested The EV kit comes with the MAX4936ACTO+ installed, but can also be used to evaluate the MAX4937A with IC replacement of U1. Warning: The EV kit is designed to operate with high voltages. Dangerous voltages are present on this EV kit Ordering Information appears at end of data sheet. and on equipment connected to it. Users who power up this EV kit or the power sources connected to it must be careful to follow safety procedures appropriately to work with high-voltage electrical equipment.
