Product Details
The ADG5421 is a monolithic industrial CMOS analog switch containing two independent latch-up immune single-pole/single-throw (SPST) switches. Each switch conducts equally well in both directions when on, and has an input signal range that extends to the power supplies. In the off condition, signal levels up to the supplies are blocked. Both ADG5421 switches are turned on with a Logic 1 input.The ultralow on resistance and on-resistance flatness of these switches make them ideal solutions for data acquisition and gain switching applications, where low distortion is critical. The latch-up immune construction, and high ESD rating, makes these switches more robust in harsh environments.
PRODUCT HIGHLIGHTS
- Trench isolation guards against latch-up. A dielectric trench
separates the P and N channel transistors thereby preventing
latch-up even under severe overvoltage conditions. - Low RON.
- Dual-supply operation. For applications where the analog signal is bipolar, the ADG5421 can be operated from dual supplies up to ±22 V.
- Single-supply operation. For applications where the analog
signal is unipolar, the ADG5421 can be operated
from a single-rail power supply up to 40 V. - 3 V logic compatible digital inputs: VINH = 2.0 V, VINL = 0.8 V.
- No VL logic power supply required.
- Available in 10-lead MSOP package.
APPLICATIONS
- High voltage signal routing
- Automatic test equipment
- Analog front-end circuits
- Precision data acquisition
- Industrial Instrumentation
- Amplifier gain select
- Relay replacement
