Low-Voltage Single-Supply, SPDT Analog Switch in SC-70

Transcription

1 Low-oltage Single-Supply, SPDT Analog Switch in SC-7 DESCRIPTION The DG499 is a cost effective upgrade to other types of 499 low-voltage, single-pole/double-throw analog switches available in the industry today. Combining low power, high speed, low on-resistant and small physical size, the DG499 is ideal for portable and battery powered applications. The DG499 is built on s low voltage CMOS process. An epitaxial layer prevents latchup. Break-before - make is guaranteed for DG499. Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off.
