DG403B VISHAY [Vishay Siliconix], DG403B Datasheet - Page 8

• Manufacturer Part Number: DG403B
• Description: Low-Power, High-Speed CMOS Analog Switches
• Manufacturer: VISHAY [Vishay Siliconix]

Dual Slope Integrators
The DG403B is well suited to configure a selectable slope
integrator. One control signal selects the timing capacitor C
or C
preparation for the next integration cycle.
Band-Pass Switched Capacitor Filter
Single-pole double-throw switches are a common element for
switched capacitor networks and filters. The fast switching
times and low leakage of the DG403B allow for higher clock
rates and consequently higher filter operating frequencies.
