Low-Voltage, Dual Supply, SPST, High Performance Analog Switches
The Intersil ISL43112 and ISL43113 are precision, high performance analog switches designed to operate from to ±6V supplies. These devices are fully specified for 10% tolerance ±5V and ±3.3V supplies, and feature supply and leakage currents much lower than those of other single SPST switches. Turn-on and turn-off times are also improved. Targeted applications include battery powered equipment that benefit from the devices' low power consumption (250µW), subnanoamp leakage currents, and fast switching speeds (tON = 40ns, tOFF = 25ns). The small SOT-23 packages, and timing that delivers break-before-make operation, make this family ideal for custom multiplexer applications. Additionally, excellent RON flatness maintains signal fidelity over the whole input range, while micro packaging alleviates board space limitations. All these benefits combine to make Intersil's newest line of low-voltage switches ideal solutions for "Next Generation" designs. The ISL4311X are single-pole/single-throw (SPST) switches, with the ISL43112 being normally open (NO), and the ISL43113 being normally closed (NC). Table 1 summarizes the performance of this family. For single supply versions, see the ISL43110/11 datasheet..TABLE 1. FEATURES AT A GLANCE ISL43112 Number of Switches Configuration / 37ns
