The ADG511 and ADG512 differ only in that the digital control logic is inverted. The ADG511 switch is turned on with a logic low on the appropriate control input, while a logic high is required for the ADG512. The ADG513 contains two switches whose digital control logic is similar to that of the ADG511 while the logic is inverted in the remaining two switches. PRODUCT HIGHLIGHTS GENERAL DESCRIPTION The ADG511, ADG512 and ADG513 are monolithic CMOS ICs containing four independently selectable analog switches. These switches feature low, well-controlled on resistance and wide analog signal range, making them ideal for precision analog signal switching. These switch arrays are fabricated using Analog Devices’ advanced linear compatible CMOS (LC2MOS) process which offers the additional benefits of low leakage currents, ultralow power dissipation and low capacitance for fast switching speeds with minimum charge injection. These features make the ADG511, ADG512 and ADG513 the optimum choice for a wide variety of signal switching tasks in precision analog signal processing and data acquisition systems. 1. +5 Volt Single Supply Operation The ADG511/ADG512/ADG513 offers high performance, including low on resistance and wide signal range, fully specified and guaranteed with +3 V, ± 5 V as well as +5 V supply rails. 2. Ultralow Power Dissipation CMOS construction ensures ultralow power dissipation. 3. Low RON 4. Break-Before-Make Switching Switches are guaranteed to have break-before-make operation. This allows multiple outputs to be tied together for multiplexer applications without the possibility of momentary shorting between channels. 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.

Only one absolute maximum rating may be applied at any one time. 2 Overvoltages at IN, S or D will be clamped by internal diodes. Current should be limited to the maximum ratings given. CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection.

Accurate Sample-and-Hold 110 VDD = +5V VSS = –5V TRENCH ISOLATION The MOS devices that make up the ADG511A/ADG512A/ ADG513A are isolated from each other by an oxide layer (trench) (see Figure 10). When the NMOS and PMOS devices are not electrically isolated from each other, there exists the possibility of “latch-up” caused by parasitic junctions between CMOS transistors. Latch-up is caused when P-N junctions that are normally reverse biased, become forward biased, causing large currents to flow. This can be destructive.

An AD845 is used as the input buffer while the output operational amplifier is an OP07. During the track mode, SW1 is closed and the output VOUT follows the input signal VIN. In the hold mode, SW1 is opened and the signal is held by the hold capacitor CH. CMOS devices are normally isolated from each other by Junction Isolation. In Junction Isolation the N and P wells of the CMOS transistors form a diode that is reverse biased under normal operation. However, during overvoltage conditions, this diode becomes forward biased. A Silicon-Controlled Rectifier (SCR)-type circuit is formed by the two transistors, causing a significant amplification of the current that, in turn, leads to latch-up. With Trench Isolation, this diode is removed; the result is a latch-up-proof circuit. VS Due to switch and capacitor leakage, the voltage on the hold capacitor will decrease with time. The ADG511/ADG512/ ADG513 minimizes this droop due to its low leakage specifications. The droop rate is further minimized by the use of a polystyrene hold capacitor. The droop rate for the circuit shown is typically 15 µV/µs.

Since both switches will be at the same potential, they will have a differential effect on the op amp OP07, which will minimize charge injection effects. Pedestal error is also reduced by the compensation Figure 10. Trench Isolation –8– REV. B ADG511/ADG512/ADG513 Test Circuits IDS V1 S S A D D S A D VD RON = V1/IDS 1. On Resistance 2. Off Leakage 3.
