GENERAL DESCRIPTION

The ADG701/ADG702 are monolithic CMOS SPST switches.

These switches are designed on an advanced submicron process

that provides low power dissipation yet high switching speed,

low on resistance, and low leakage currents. In addition, −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 the new generation of DACs and ADCs from Analog

Devices, Inc.

Figure 1 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 ADG701/ADG702 are available in 5-lead SOT-23, 6-lead

SOT-23, and 8-lead MSOP packages.

PRODUCT HIGHLIGHTS

1. 1.8 V to 5.5 V Single-Supply Operation.

The ADG701/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.

2. Ver y Low R

(3 Ω Maximum at 5 V, 5 Ω Maximum at 3 V).

At 1.8 V operation, R

is typically 40 Ω over the tempera-

ture range.

3. On Resistance Flatness R

FLAT(ON)

(1 Ω Maximum).

4. −3 dB Bandwidth > 200 MHz.

5. Low Power Dissipation.

CMOS construction ensures low power dissipation.

6. Fast t
