DG405DY

单片CMOS模拟开关 Monolithic CMOS Analog Switches

The DG401, DG403 and DG405 monolithic CMOS analog switches have TTL and CMOS compatible digital inputs.

These switches feature low analog ON resistance <45Ω and fast switch time tON < 150ns. Low charge injection simplifies sample and hold applications.

The improvements in the DG401/403/405 series are made possible by using a high voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS technologies. The 44V maximum voltage range permits controlling 30VP-P signals. Power supplies may be single-ended from +5V to +34V, or split from ±5V to ±17V.
