CMOS, Low Voltage, IC Compatible Interface, Serially Controlled, Octal SPST Switches

The ADG715 is a complementary metal-oxide semiconductor (CMOS), octal single-pole, single-throw (SPST) switch controlled via a 2- wire serial interface. On resistance is closely matched between switches and is flat over the full signal range. Each switch conducts equally well in both directions and the input signal range extends to the supplies. Data is written to these devices in the form of 8 bits, each bit corresponding to one channel.

The ADG715 uses a 2-wire serial interface that is compatible with the I2C interface standard. The ADG715 has four hardwired addresses, selectable from two external address pins (A0 and A1). The pins allow the two LSBs of the 7-bit slave address to be set by the user. A maximum of four of these devices may be connected to the bus.

On power-up, all switches are in the OFF condition, and the internal registers contain all zeros.

A low power consumption and operating supply range of 2.7 V to 5.5 V makes this part ideal for many applications. The ADG715 may also be supplied from a dual ±2.5 V supply. The ADG715 is available in a 24-lead TSSOP.
