CBMG781
Preview
CMOS, low voltage, 2.5 Ω, quad SPST switch

CBMG781 is a single-chip CMOS device with four independent optional switches built-in. It adopts advanced submicron process design, with low power consumption, high switching speed, low on resistance, low leakage current, and high bandwidth characteristics.

The CBMG781 is powered by a single power supply ranging from+1.8 V to+5.5 V, making it ideal for use in battery powered instruments.
