The ADG714 is a complementary metal-oxide semiconductor (CMOS), octal single-pole, single-throw (SPST) switch controlled via a 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.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 ADG714 may also be supplied from a dual ±2.5 V supply.

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.

TheADG721, ADG722, andADG723are monolithic CMOS SPST switches. These switches are designed on an advanced submicron process that provides low power dissipation yet gives high switching speed, low on resistance, and low leakage currents. The devices are packaged in both a tiny 3 mm × 2 mm LFCSP and an MSOP, making them ideal for space-constrained applications.The ADG721, ADG722, and ADG723 are designed to operate from a single 1.8 V to 5.5 V supply, making them ideal for use in battery-powered instruments and with the new generation of DACs and ADCs from Analog Devices, Inc.The ADG721, ADG722, and ADG723 contain two independent single-pole/single-throw (SPST) switches. The ADG721 and ADG722 differ only in that both switches are normally open and normally closed, respectively. In the ADG723, Switch 1 is normally open and Switch 2 is normally closed.Each switch of the ADG721, ADG722, and ADG723 conducts equally well in both directions when on. The ADG723 exhibits break-before-make switching action.PRODUCT HIGHLIGHTS1.8 V to 5.5 V single-supply operation.Very low RON(4 Ω max at 5 V, 10 Ω max at 3 V).Low on resistance flatness.−3 dB bandwidth >200 MHz.Low power dissipation.

The ADG731/ADG725 are monolithic, CMOS, 32-channel/dual 16-channel analog multiplexers with a serially controlled 3-wire interface. The ADG731 switches one of 32 inputs (S1–S32) to a common output, D. The ADG725 can be configured as a dual mux switching one of 16 inputs to one output, or a differential mux switching one of 16 inputs to a differential output.These mulitplexers utilize a 3-wire serial interface that is compatible with SPI®, QSPI™, MICROWIRE™, and some DSP interface standards. On power-up, the Internal Shift Register contains all zeros and all switches are in the OFF state.These multiplexers are designed on an enhanced submicron process that provides low power dissipation yet gives high switching speed with very low on resistance and leakage currents. They operate from a single supply of 1.8 V to 5.5 V or a ±2.5 V dual supply, making them ideally suited to a variety of applications. On resistance is in the region of a few ohms, is closely matched between switches, and is very flat over the full signal range.These parts can operate equally well as either multiplexers or demultiplexers and have an input signal range that extends to the supplies. 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.The ADG731 and ADG725 are serially controlled 32-channel, and dual/differential 16-channel multiplexers, respectively. They are available in either a 48-lead LFCSP or TQFP package.Product Highlights3-Wire Serial Interface.1.8 V to 5.5 V Single-Supply or ±2.5 V Dual-Supply Operation.

The ADG728 also has aRESETpin that should be tied high if not in use.Each channel is controlled by one bit of an 8-bit word.
