... Component landings are available for an optional EMI output filter. The CDB35L00-X4 can be configured to evaluate the four operational modes and two gain settings of the CS35L00 amplifier. Mode, Gain, and Shutdown control is available through the S1 switch. Hybrid control is available through the R13, R23, R33, and R43 resistors ...

... Power Supply A single +2.5 to +5.5 VDC power supply is required to power the CDB35L00-X4. The supply must be capa- ble of delivering sufficient current for the intended power output. The supply provides power to each of the four CS35L00 amplifiers. The power supply connection to the board is provided by the header J1. The pos- itive terminal is labeled VBATT ...

... Table 2. Hybrid Control Resistor & S1 Switch MODE Configurations 1.4 Shutdown Control The S1 switch implements shutdown control for the four CS35L00 devices on the CDB35L00-X4. SD1-2 controls the shutdown for U1 and U2. SD3-4 controls the shutdown for U3 and U4 as shown in on the schematic in Figure 4 on page ...

... Optional Gain Adjustment Resistors The CDB35L00-X4 contains optional gain adjustment resistor placeholders for each CS35L00 device (R11, R12, R21, R22, R31, R32, R41, R42). By default these are not populated and the CS35L00 oper- ates at its gain control setting as set by the S1 switch. See necessary when a gain gain of + not desired ...

... Optional Speaker Output EMI Filter Components The CDB35L00-X4 contains optional placeholders for a series ferrite bead (FB11, FB12, FB21, FB22, FB31, FB32, FB41, FB42) and shunt capacitor (C16, C17, C26, C27, C36, C37, C46, C47) output filter. For most applications with very short speaker leads between the CS35L00 and the speaker, use of these components will not be necessary ...

... The small value decoupling capacitors are placed as close as possible to the power pins of the CS35L00 on the CDB35L00-X4 board recommended that the power supply decoupling capacitors reside on the opposite side of the board from which the CS35L00 is populated on. This allows for very close placement of the decoupling capacitors to the power supply pins of the CS35L00 without interfering with the differential audio inputs or differential audio outputs ...
