The ADG732 switches one of thirty-two inputs (S1-S32) to a common output, D, as determined by the 5-bit binary address lines A0, A1, A2, A3 and A4. The ADG726 switches one of sixteen inputs as determined by the four bit binary address lines, A0, A1, A2 and A3. On chip latches facilitate microprocessor interfacing. The ADG726 device may also be configured for differential operation by tying CSA and CSB together. An EN input is used to enable or disable the devices. When disabled, all channels are switched OFF. These multiplexers are designed on an enhanced submi- cron process that provides low power dissipation yet gives high switching speed, very low on resistance and leakage currents. They operate from single supply of 1.8V to 5.5V and ±2.5 V dual supply, making them ideally suited to a variety of applications. On resistance is in the region of a few Ohms and is closely matched between switches and very flat over the full signal range. These parts can operate equally well as either Multiplexers or De-Multiplexers PRODUCT HIGHLIGHTS 1. +1.8 V to +5.5 V Single or ±2.5 V Dual Supply operation. These parts are specified and guaranteed with +5 V ±10%, +3 V ±10% single supply and ±2.5 V ±10% dual supply rails. 2. On Resistance of 3.5 Ω. 3. Guaranteed Break-Before-Make Switching Action. 4. 7mm x 7mm 48 lead LF Chip Scale Package (CSP) or 48 lead TQFP package. FUNCTIONAL BLOCK DIAGRAMS S1 S32 A0 D A3 A1 ADG732 EN 1 OF 32 DECODER A2 A4 WR S1A A1 DA A2 S16A S1B S16B DB EN ADG726 1 OF 16 DECODER A3 A0 WR CSA CS CSB and have an input signal range which extends to the sup- plies. In the OFF condition, signal levels up to the supplies are blocked. All channels exhibit break before make switching action preventing momentary shorting when switching channels. They are available in either 48 lead LFCSP or TQFP package. |
