Analog Devices ADG5412 and ADG5413 Switches
Analog Devices announced the ADG5412 and ADG5413 switches that can prevent latch-up in high-voltage industrial applications operating up to ±20 V. The ADG5412 and ADG5413 are ideal for instrumentation, automotive, and other harsh environments that are prone to latch-up, which is an undesirable high-current state that can lead to device failure and persist until the power supply is turned off. The high voltage switches feature a 8-kV HBM (human body model) ESD (electrostatic discharge) rating. This helps shield equipment from excess current and eliminates the need for designers to install additional protection circuitry. The ADG5412 and ADG5413 switches are available now for $2.18 (price each per 1,000).
ADG5412 and ADG5413 Switches Highlights
- Latch-up proof
- 8 kV human body model (HBM) ESD rating
- Low on resistance less than 10 ohms
- Fast switching times 170ns
- ±9-V to ±20-V dual supply operation
- 9-V to 40-V single supply operation
- 48-V supply maximum ratings
- Fully specified at ±15 V, ±20 V, +12 V, +36 V
- Rail-to-rail (VSS to VDD) analog signal range
The ADI ADG5412 and ADG5413 switches feature four independent SPST (single-pole, single-throw) switches. For applications where the analog signal is bipolar, the switches can be operated from dual supplies up to ±20 V. For applications where the analog signal is unipolar, the new switches can be operated from a single-rail power supply up to 40 V. 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. All switches exhibit break-before-make switching action for use in multiplexer applications.
