7 / 16 page REV. A ADG725/ADG731 –7– PIN CONFIGURATIONS PIN FUNCTION DESCRIPTIONS ADG725 ADG731 Mnemonic Function 1–12, 25–40, 1–12, 25–40, Sxx Source. May be an input or output. 45–48 45–48 13, 14 13, 14 VDD Power Supply Input. These parts can be operated from a single supply of 1.8 V to 5.5 V and a dual supply of ±2.5 V. 17 17 SYNC Active Low Control Input. This is the frame synchronization signal for the input data. When SYNC goes low, it powers on the SCLK and DIN buffers and the input Shift Register is enabled. An 8-bit counter is also enabled. Data is transferred on the falling edges of the following clocks. After eight falling clock edges, switch conditions are automatically updated. SYNC may be used to frame the signal or just pulled low for a short period of time to enable the counter and input buffers. 18 18 DIN Serial Data Input. Data is clocked into the 8-bit Input Register MSB first on the falling edge of the serial clock input. 19 19 SCLK Serial Clock Input. Data is clocked into the Input Shift Register on the falling edge of the serial clock input. These devices can accommodate serial input rates of up to 30 MHz. 23 23 GND Ground Reference 24 24 VSS Most Negative Power Supply in a Dual-Supply Application. In single-supply applications, connect to GND. 41, 43 N/A DA, DB Drain. May be an input or output. N/A 43 D Drain. May be an input or output. 48-Lead LFCSP and TQFP 36 35 34 33 32 31 30 29 28 27 26 25 13 14 15 16 17 18 19 20 21 22 23 24 1 2 3 4 5 6 7 8 9 10 11 12 48 47 46 45 44 39 38 37 43 42 41 40 PIN 1 IDENTIFIER TOP VIEW (Not to Scale) S28 S27 S26 S25 S24 S23 S22 S12 S11 S10 S9 S8 S7 S6 NC = NO CONNECT S5 S4 S3 S2 S21 S20 S19 S18 ADG731 S1 S17 36 35 34 33 32 31 30 29 28 27 26 25 13 14 15 16 17 18 19 20 21 22 23 24 1 2 3 4 5 6 7 8 9 10 11 12 48 47 46 45 44 39 38 37 43 42 41 40 PIN 1 IDENTIFIER TOP VIEW (Not to Scale) S12B S11B S10B S9B S8B S7B S6B S12A S11A S10A S9A S8A S7A S6A NC = NO CONNECT S5A S4A S3A S2A S5B S4B S3B S2B ADG725 S1A S1B |
