Analog Devices Inc. ADG5401F Fault Protection SPST Switch
Analog Devices Inc. ADG5401F Fault Protection SPST Switch features overvoltage protection, power-off protection, and overvoltage detection on the source pins (S and SFB). The ADG5401F has a protected secondary feedback channel for use with a digital-to-analog converter (DAC) or amplifier outputs. When no power supplies are present, the switch remains in the off condition, and the switch inputs are high impedance.
Features
- Analog output protection and detection solution
- Overvoltage Protection up to ±60V on S and SFB pins
- Power off protection up to ±60V on S and SFB pins
- Integrated 0.6kΩ secondary feedback channel
- Known output under all conditions
- User enabled, power-on condition pulls source to 0V
- Known state without digital inputs present
- Optimized resistance for the measurement channel and feedback channel
- Low on-resistance of 6Ω typical on signal channel
- Ultraflat, on resistance on the signal channel
- Latch-up immune
- 3mm × 2mm LFCSP
- VSS to VDD −2V signal range
- Fully specified at ±15V, ±20V, +12V, and +36V
- ±5V to ±22V dual-supply operation
- 8V to 44V single-supply operation
Applications
- DAC output protection
- Amplifier output protection
- Analog output modules
- Process control/distributed control systems
- Data acquisition
- Instrumentation

Robustness for Analog Outputs in Process Control
Precision analog output modules, known as programmable logic controllers (PLCs) or distributed control systems (DCS), produce voltage or current outputs used for accurate and robust control of actuators that manage process parameters such as flow, temperature, and pressure. These modules need to deliver robust, reliable, and precise outputs in harsh industrial environments.
