AD7875/AD7876/AD7878 PRODUCT HIGHLIGHTS GENERAL DESCRIPTION
1. 5 Volt Single Supply Operation The ADG511, ADG512 and ADG513 are monolithic CMOS The ADG511/ADG512/ADG513 offers high performance, ICs containing four independently selectable analog switches. including low on resistance and wide signal range, fully These switches feature low, well-controlled on resistance and specified and guaranteed with +3 V, ± 5 V as well as +5 V wide analog signal range, making them ideal for precision supply rails. analog signal switching. 2. Ultralow Power Dissipation These switch arrays are fabricated using Analog Devices’ CMOS construction ensures ultralow power dissipation. advanced linear compatible CMOS (LC2MOS) process which 3. Low RON offers the additional benefits of low leakage currents, ultralow 4. Break-Before-Make Switching power dissipation and low capacitance for fast switching speeds Switches are guaranteed to have break-before-make opera- with minimum charge injection. These features make the tion. This allows multiple outputs to be tied together for ADG511, ADG512 and ADG513 the optimum choice for a multiplexer applications without the possibility of momentary wide variety of signal switching tasks in precision analog signal shorting between channels. processing and data acquisition systems. The ability to operate from single +3 V, +5 V or ± 5 V bipolar supplies make the ADG511, ADG512 and ADG513 perfect for use in battery-operated instruments, 4–20 mA loop systems and with the new generation of DACs and ADCs from Analog Devices. The use of 5 V supplies and reduced operating currents give much lower power dissipation than devices operating from ±15 V supplies. REV.
