11 / 26 page No. 6108-11/26 LC75397E Continued from preceding page. Pin No. Pin Function Equivalent circuit • A capacitor with a value of a few tens of µF must be inserted between Vref and AVSS (VSS) to reduce power supply ripple in the 0.5 × VDD voltage generator block used for analog ground. 21 Vref • Chip enable When this pin goes from high to low, data is written to an internal latch and the analog switches operate. Data transfers are enables when this pin is at the high level. 25 CE • Electronic volume control test pin. This pin must be held at the VSS potential. 22 TEST • Unused pins. These pins must either be left open or connected to VSS. 16 17 20 27 28 29 57 NC • Serial data and clock inputs for chip control 24 23 DI CL Ground 56 VSS Power supply 26 VDD |
