Analog Selector Switch (SP 944)

The Analog Selector Switch allows fast and low-glitch switching between two analog voltages in a range of up to ±10 V. To prevent from interferences and ground-loops the TTL-compatible control input is galvanically isolated by an optocoupler. The low noise performance combined with the low ON-resistance (<200 Ohm) and a charge-injection smaller than 1 pC makes this switch suitable for high-sensitive physics experiments. The device can be mounted directly to the BNC connectors on the front-panel of the LNHR DAC (SP 927) and allows fast switching (up to 100 kHz) between two different low noise output voltages.
