ADG715

Data Sheet CMOS, Low Voltage Serially Controlled, Octal SPST Switches ADG714/ADG715 FEATURES SPI/QSPI/MICROWIRE-compatible interface (ADG714) ADG715: I2C-compatible interface (ADG715) 2.7 V to 5.5 V single supply ±2.5 V dual supply 2.5 Ω on resistance 0.6 Ω on resistance flatness 0.1 nA leakage currents Octal SPST Power-on reset Fast switching times TTL/CMOS compatible 24-lead TSSOP and 24-lead LFCSP APPLICATIONS Data acquisition systems Communication systems Relay replacement Audio and video switching GENERAL DESCRIPTION The ADG714/ADG715 are complementary metal-oxide semiconductor (CMOS), octal single-pole, single-throw (SPST) switches, controlled via either a 2- or 3-wire serial interface. On resistance is closely matched between the 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 ADG714 uses a 3-wire serial interface that is compatible with serial peripheral interface (SPI), QSPI™, MICROWIRE™ interface standards, and most digital signal processing (DSP) interface standards. The output of the shift register DOUT enables a number of these devices to be daisy-chained. 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...
