• Low On-resistance: RON(max) = 10Ω (@V_DD = 5 V)

• Low Off-resistance: ROFF(max) = 500Ω (@V_DD = 5 V)

• Low operating voltage: V_DD (max) = 7V

• Low power dissipation: ID (max) = 96 uA

• Low charge injection: C_n(max) = 0.7 pC

Application Fields of DG419LDY+T

The DG419LDY+T is designed to provide high performance in a variety of applications. It is ideal for analog signal routing, signal gating, and digital-to-analog converter (DAC) sampling applications. The low power dissipation of the device makes it especially well suited for portable applications where battery life is critical. It can also be used in cellular phone and pager applications, DVD players, signal multiplexers and demultiplexers, digital audio systems, instrumentation systems, and data acquisition systems.

Working Principle of DG419LDY+T

The DG419LDY+T is a quad SPST analog switch designed to provide additional flexibility and increased performance in high-speed applications. The DG419LDY+T implements four independent switches, each with its own control signal (IN1, IN2, IN3, IN4) and common signal (COM). When a control signal is applied to the switch, the input signal is routed to the output, otherwise the output is disconnected from all terminals. The control signal is designed to be compatible with both TTL/CMOS and ECL logic families.

The device features low resistance paths, low charge injection, and low power dissipation. The on-resistance of the device is 10 Ω (maximum) at 5 V and the off-resistance is 500 Ω (maximum) at 5 V. The device has a low operating voltage of 7 V and a low power dissipation of 96 uA (maximum). The low charge injection of the device is 0.7 pC (maximum) for devices powered at 5 V.

The DG419LDY+T is designed for high-speed applications, such as analog signal routing, signal gating, and digital-to-analog converter (DAC) sampling applications. With its low power dissipation and charge injection features, the device is well suited for portable applications. The device can also be used in a variety of other applications, such as cellular phones and pagers, DVD players, signal multiplexers and demultiplexers, digital audio systems, instrumentation systems, and data acquisition systems.
