austriamicrosystems AS1744
The AS1744/AS1745 are high-speed, low-voltage, dual single-pole/double-throw (SPDT) analog switches. These highly-reliable devices operate from a +1.8 to +5.5V supply, are differentiated by inverted logic, and support break-before-make switching. With low ON-resistance (RON), RON matching, and RON flatness, the devices can accurately switch signals for sample and hold circuits, digital filters, and op-amp gain switching networks.
