CMOS Low Voltage 2 Ω SPST Switch

The ADG702 is a monolithic CMOS SPST switch. It is designed on an advanced submicron process that provides low power dissipation yet high switching speed, low on resistance, low leakage currents and -3 dB bandwidths of greater than 200 MHz can be achieved.

The ADG701 / ADG702 can operate from a single 1.8 V to 5.5 V supply, making it ideal for use in battery-powered instruments and with Analog Devices' new generation of DACs and ADCs.

ADG702 Functional Block Diagram shows that with a logic input of 1, the switch of the ADG701 is closed and that of the ADG702 is open. Each switch conducts equally well in both directions when on.

The ADG702 are available in 5-lead SOT-23, 6-lead SOT-23, and 8-lead MSOP packages.

PRODUCT HIGHLIGHTS

* 1.8 V to 5.5 V Single-Supply Operation. ADG702 offer high performance, including low on resistance and fast switching times, and are fully specified and guaranteed with 3 V and 5 V supply rails.

* Very Low RON (3 Ω Maximum at 5 V, 5 Ω Maximum at 3 V). At 1.8 V operation, RON is typically 40 Ω over the temperature range.

* On Resistance Flatness RFLAT(ON) (1 Ω Maximum).

* −3 dB Bandwidth > 200 MHz

* Low Power Dissipation. CMOS construction ensures low power dissipation.

* Fast tON/tOFF.

* 1.8 V to 5.5 V Single Supply

* 2O (Typ) On Resistance

* Low On-Resistance Flatness

* -3 dB Bandwidth >200 MHz

* Rail-to-Rail Operation

* Tiny 6-Lead SOT23 and 8-Lead µSOIC packages
