64 / 71 page  Supply Ramp Supply DR_SD Time for AC-Coupling Capacitors to Charge T0463-02 Inverting Input –In TAS5721 R1 R2 + – C3 R3 C1 C2 TAS5721 SLOS739 – JULY 2012 www.ti.com The component values can be calculated with the help of the TI FilterPro™ program available on the TI website at: focus.ti.com Figure 76. Second-Order Active Low-Pass Filter The resistor values should have a low value for obtaining low noise, but should also have a high enough value to get a small size ac-coupling cap. The C2 can be split in two with the midpoint connected to GND; this can increase the common-mode attenuation. Pop-Free Power Up Pop-free power up is ensured by keeping the DR_SD low during power supply ramp up and down. The pin should be kept low until the input AC-coupling capacitors are fully charged before asserting the DR_SD pin high, this way proper precharge of the AC-coupling capacitors is performed and pop-less power up is achieved. Figure 77 illustrates the preferred sequence. Figure 77. Power Up or Down Sequence 64 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Product Folder Links: TAS5721 |
