Overview
The ADG715BRUZ, produced by Analog Devices Inc., is a complementary metal-oxide semiconductor (CMOS), octal single-pole, single-throw (SPST) switch. This device is controlled via a 2-wire serial interface that is compatible with the I2C interface standard. The ADG715 features closely matched on-resistance values between switches, which remain flat over the full signal range. Each switch conducts equally well in both directions, and the input signal range extends to the supplies. This makes the ADG715 an ideal choice for various applications requiring precise signal switching.
