NCS2632DTBGEVB NCS2632 Evaluation Board User's Manual http://onsemi.com Introduction This document gives a description of the NCS2632 evaluation board with the bill of materials (BOM), board schematic, and evaluation setup. The NCS2632 evaluation board has been designed to help for a quick evaluation of the NCS2632 audio line driver performance. This document is to be used with the NCS2632 data sheet. The data sheet contains full technical details regarding the NCS2632 specifications and operation. The board is implemented in 2 metal layers. The layers have thicknesses of 35 mm (1 oz). The PCB thickness is 1.6 mm (63 mils) with dimensions of 115 × 100 mm (4.5″ × 3.9″, respectively).

NCS2632 Evaluation Board Overview http://onsemi.com 2 NCS2632DTBGEVB QUICK START PROCEDURE WITH DIFFERENTIAL SETUP 4. Use the voltmeter to measure the VSS pin. It should measure near –VDD. 5. Apply a sine wave (f = 1 kHz, 1 Vpp) across INLP and INLM. Observe the waveform at OUTL. 6. Apply a sine wave (f = 1 kHz, 1 Vpp) across INRP and INRM. Observe the waveform at OUTR. By default, each channel is set up in a differential configuration with a gain of 2 V/V. Follow this procedure to quickly get familiar with the evaluation board features. 1. Make sure that the VDD jumper and UVP detection supply jumper are in place. Remove all input jumpers to ground. Table 1 summarizes the position of each switch and jumper. 2. Connect a 3.3 V supply between the VDD pin and GND. 3. Set the EN switch to high to enable the IC. Check the supply current. Verify that EN is high with a multimeter, if necessary. For more information and circuit examples refer to the Application Information section in the data sheet. Table 1.
