The features of the EV kits enable evaluation Connectors of the analog switches through audio jack inputs and outputs, as well as SMA connectors for AC characteristic Quickly Evaluate Audio Performance with 3.5mm evaluation. Input power to the EV kits is provided by a Audio Jack Connectors Micro-USB, type-B connector or an external power supply. USB 5V Power with On-Board Adjustable LDO Ordering Information appears at end of data sheet. 4) Verify that jumper JU3 has a shunt installed shorting Quick Start pins 1-2. This shorts the control bit (CB) on the device Required Equipment to GND, electrically connecting NC1 to COM1 and MAX14589E, MAX14594E, or MAX14689 EV kit NC2 to COM2. USB power supply or 1.8V to 5.5V power supply 5) Connect an audio source to the normally closed audio jack (P2), using the male-to-male 3.5mm audio cable Audio source (e.g., MP3 player, computer, etc.) included with the EV kit. External speakers or headphones with 3.5mm audio 6) Connect external speakers or headphones to the jack common audio jack (P3). Procedure 7) When the audio source outputs the audio signal, and The EV kits are fully assembled and tested. Follow the JU3 has a shunt shorting pins 1-2, the audio signal steps below to verify board operation and begin evaluation: should be heard on the speakers or headphones 1) If using a USB power supply to power the board through connected at P3. the Micro-USB connector (J1), verify that a shunt is 8) Move the shunt on JU3 from pins 1-2 to pins 2-3. The installed shorting pins 3-4 on jumper JU2. This powers audio signal should no longer be heard on the speak- the device from the output of the on-board LDO. To ers or headphones connected at P3. adjust the LDO output voltage, connect a voltmeter at 9) If the audio source connection moves from the test point T3 and turn the screw on the potentiometer normally closed audio jack (P2) to the normally open (R3) until reaching the desired value. To use the raw audio jack (P1) with a shunt in position 2-3 on JU3, the bus voltage as the power supply for the device, place audio signal on the common audio jack (P3) is heard the shunt so that it is shorting pins 5-6 on JU2. on the speakers or headphones. If the shunt on JU3 2) If an external power supply is used, apply the power at is in position 1-2, there is no audio signal heard on the test point T2 and use the shunt to short pins 1-2 on JU2 speaker or headphones. to provide power to the parts from the external supply. 3) Verify that jumper JU1 has a shunt installed shorting pins 2-3, and that jumper JU4 has a shunt installed shorting pins 2-3. Installing the shunts in these locations provides power from the source to the V CC pin of the device. 19-6809 Rev 0 9/13Evaluate: MAX14589E/MAX14594E/ MAX14589E/MAX14594E/ MAX14689 Evaluation Kits MAX14689 AC Evaluation Detailed Description of Hardware The EV kits have a secondary IC configured for The MAX14589E, MAX14594E, and MAX14689 EV kits evaluation of the AC characteristics of the device. SMA are fully assembled and tested circuit boards that demon- connectors (J2J5) allow for direct connection to a strate the functionality of the MAX14589E, MAX14594E, network analyzer. 50I termination resistors (R6, R7) and MAX14689 DTDT analog switches in a 9-bump WLP. provide termination to match the typical 50 source The EV kit features enables evaluation of the analog resistance of the network analyzer, allowing for easy switches through audio jack inputs and outputs, as well evaluation of these parameters. The ability to connect as SMA connectors for AC characteristic evaluation. Input external DC bias voltages at test points T7 and T8 further power to the EV kits is provided by a Micro-USB, type-B simplifies evaluation of AC characteristics, while using a connector or an external power supply. The EV kit PCBs network analyzer that cannot provide DC offset voltages. are designed with 1oz copper. V Status LED Power Supply BUS An indicator diode (D1) is included on the EV kits, The EV kits are powered by a user-supplied 1.6V to 5.5V indicating that a V voltage is present on the Micro- BUS external DC power supply connected between V EXT USB connector (J3). If the LED glows green, power is and GND, the raw USB bus supplied at the Micro-USB present at J3 and the board can be powered by the LDO connector (J1), or the regulated output of the LDO (U2) output or by the raw V supply (see Table 1 for jumper that is powered by the USB bus. BUS configurations). The status LED does not glow when a voltage is present on test point T2. Table 1.
