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 HIGHLIGHTS 3-Wire Serial Interface. 1.8 V to 5.5 V Single-Supply or ±2.5 V Dual-Supply Operation.

The ADG733 and ADG734 are low voltage, CMOS devicescomprising three independently selectable SPDT (single pole,double throw) switches and four independently selectable SPDTswitches respectively.Low power consumption and operating supply range of 1.8 V to5.5 V and dual ±2.5 V make the ADG733 and ADG734 ideal forbattery powered, portable instruments. All channels exhibitbreak-before-make switching action preventing momentaryshorting when switching channels. An EN input on the ADG733 isused to enable or disable the device. When disabled, all channelsare switched OFF.These 2–1 multiplexers/SPDT switches are designed on anenhanced submicron process that provides low power dissipationyet gives high switching speed, very low on resistance, high signalbandwidths, and low leakage currents. On resistance is in theregion of a few ohms, is closely matched between switches, and isvery flat over the full signal range. These parts can operate equallywell in either direction and have an input signal range that extendsto the supplies.The ADG733 is available in small TSSOP and QSOP packages,while the ADG734 is available in a small TSSOP package.PRODUCT HIGHLIGHTS Single/Dual Supply Operation. The ADG733 and ADG734 are fully specified and guaranteed with 3 V and 5 V single supply rails and ±2.5 V dual supply rails.

The DG201A and DG211 are normally closed, quadsingle-pole single-throw (SPST) analog switches. TheseCMOS switches can be continuously operated withpower supplies ranging from ±4.5V to ±18V. Maximguarantees that these switches will not latch up if thepower supplies are disconnected with input signals stillconnected.Both devices have guaranteed break-before-makeswitching. The DG201A differs from the DG211 primarilyin switching speeds. The DG201A has a maximumturn-off time of 450ns and a maximum turn-on time of600ns. The DG211 has a maximum turn-off time of500ns and a maximum turn-on time of 1000ns.Compared to the original manufacturer's products,Maxim's DG201A and DG211 consume significantlylower power making them better suited for portableapplications. Maxim has also eliminated the need forthe third (VL) power supply that is required for the operationof the original manufacturer's DG211.ApplicationsCommunication SystemsGuidance and Control SystemsHeads-Up DisplaysMilitary RadiosPBX, PABXTest EquipmentWinchester Disk Drives
