1. DESCRIPTION
The ADG419BRMZ is a monolithic CMOS SPDT switch. This switch is designed on an enhanced LC2 MOS process that provides low power dissipation yet gives high switching speed, low on resistance, and low leakage currents. The on resistance profile of the ADG419 is very flat over the full analog input range, ensuring excellent linearity and low distortion. The part also exhibits high switching speed and high signal bandwidth. CMOS construction ensures ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments. Each switch of the ADG419 conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. The ADG419 exhibits break-before-make switching action.
2. PRODUCT HIGHLIGHTS
1. Extended Signal Range. The ADG419 is fabricated on an enhanced LC2 MOS process, giving an increased signal range that extends to the supply rails.
2. Ultralow Power Dissipation.
3. Low RON.
4. Single-Supply Operation.
For applications where the analog signal is unipolar, the ADG419 can be operated from a single rail power supply. The part is fully specified with a single 12 V power supply and remains functional with single supplies as low as 5 V
