1. Extended Signal Range. 2. The ADG406/ADG407/ADG426 are fabricated on an enhanced LC2 MOS process giving an increased signal range which extends to the supply rails. 3. Low Power Dissipation. 4. Low RON. 5. Single/Dual Supply Operation. 6. Single Supply Operation. 7. For applications where the analog signal is unipolar, the ADG406/ADG407/ADG426 can be operated from a single rail power supply. The parts are fully specified with a single 12 V power supply and remain functional with single supplies as low as 5 V

The ADG441, ADG442, and ADG444 are monolithic CMOS devices that comprise of four independently selectable switches. They are designed on an enhanced LC2 MOS process that provides low power dissipation yet gives high switching speed and low on resistance. The on resistance profile is very flat over the full analog input range, which ensures good linearity and low distortion when switching audio signals. High switching speed also makes the parts suitable for video signal switching. CMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments. The ADG441, ADG442, and ADG444 contain four independent SPST switches. Each switch of the ADG441 and ADG444 turns on when a logic low is applied to the appropriate control input. The ADG442 switches are turned on with logic high on the appropriate control input. The ADG441 and ADG444 switches differ in that the ADG444 requires a 5 V logic power supply that is applied to the VL pin. The ADG441 and ADG442 do not have a VL pin, the logic power supply is generated internally by an on-chip voltage generator.

The ADM690?ADM695 family of supervisory circuits offers complete single chip solutions for power supply monitoring and battery control functions in microprocessor systems. These functions include ?P reset, backup battery switchover, watchdog timer, CMOS RAM write protection, and power failure warning. The complete family provides a variety of configurations to satisfy most microprocessor system requirements. The ADM690, ADM692 and ADM694 are available in 8-pin DIP packages and provide: 1. Power-on reset output during power-up, power-down and brownout conditions. The RESET output remains operational with VCC as low as 1 V. 2. Battery backup switching for CMOS RAM, CMOS microprocessor or other low power logic. 3. A reset pulse if the optional watchdog timer has not been toggled within a specified time. 4. A 1.3 V threshold detector for power fail warning, low battery detection, or to monitor a power supply other than 5 V.

The ADM705/ADM706/ADM707/ADM708 microprocessor supervisory circuits are suitable for monitoring 5 V power supplies/batteries and microprocessor activity. The ADM705/ADM706 provide power-supply monitoring circuitry that generate a reset output during power-up, powerdown, and brownout conditions. The reset output remains operational with VCC as low as 1 V. Independent watchdog monitoring circuitry is also provided. This is activated if the watchdog input has not been toggled within 1.60 sec. In addition, there is a 1.25 V threshold detector to warn of power failures, to detect low battery conditions, or to monitor an additional power supply. An active low, debounced manual reset input (MR) is also included.
