On S8 D8 resistance is closely matched between the switches and is flat INTERFACE over the full signal range. Each switch conducts equally well in LOGIC RESET both directions, and the input signal range extends to the supplies. Data is written to these devices in the form of 8 bits, SDA SCL A0 A1 each bit corresponding to one channel. Figure 2. ADG715 Functional Block Diagram The ADG714 uses a 3-wire serial interface that is compatible with serial peripheral interface (SPI), QSPI, MICROWIRE and the ADG715 is available in a 24-lead TSSOP. interface standards, and most digital signal processing (DSP) interface standards. The output of the shift register DOUT PRODUCT HIGHLIGHTS enables a number of these devices to be daisy-chained. 1. 2- or 3-wire serial interface. The ADG715 uses a 2-wire serial interface that is compatible 2. Single-/dual-supply operation. 2 with the I C interface standard. The ADG715 has four hardwired The ADG714 and ADG715 are fully specied and addresses, selectable from two external address pins (A0 and A1). guaranteed with 3 V, 5 V, and 2.5 V supply rails. The pins allow the two LSBs of the 7-bit slave address to be set 3. Low on resistance, typically 2.5 . by the user. A maximum of four of these devices may be 4. Low leakage. connected to the bus. 5. Power-on reset. 6. A 24-lead TSSOP for both the ADG714 and the ADG715. On power-up of these devices, all switches are in the off A 24-lead LFCSP for the ADG714. condition, and the internal registers contain all zeros. A low power consumption and operating supply range of 2.7 V to 5.5 V make these devices ideal for many applications. These devices can also be supplied from a dual 2.5 V supply. The ADG714 is available in a 24-lead TSSOP and a 24-lead LFCSP, Rev. E Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
