DG417, DG418, DG419 Vishay Siliconix Precision CMOS Analog Switches DESCRIPTION FEATURES The DG417, DG418, DG419 monolithic CMOS analog switches were designed to provide high performance switching of analog signals. Combining low power, low leakages, high speed, low on-resistance and small physical size, the DG417 series is ideally suited for portable and battery powered industrial and military applications requiring high performance and efficient use of board space. • • • • • • To achieve high-voltage ratings and superior switching performance, the DG417 series is built on Vishay Siliconix’s high voltage silicon gate (HVSG) process. Break-beforemake is guaranteed for the DG419, which is an SPDT configuration. An epitaxial layer prevents latchup. Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off. The DG417 and DG418 respond to opposite control logic levels as shown in the Truth Table. ± 15 V analog signal range On-resistance - RDS(on): 20  Fast switching action - tON: 100 ns Ultra low power requirements - PD: 35 nW TTL and CMOS compatible MiniDIP and SOIC packaging • 44 V supply max. rating • 44 V supply max. rating • Compliant to RoHS directive 2002/95/EC BENEFITS • • • • • • Wide dynamic range Low signal errors and distortion Break-before-make switching action Simple interfacing Reduced board space Improved reliability APPLICATIONS • • • • • • • Precision test equipment Precision instrumentation Battery powered systems Sample-and-hold circuits Military radios Guidance and control systems Hard disk drives FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG417 Dual-In-Line and SOIC TRUTH TABLE S 1 8 D NC 2 7 V- GND 3 6 IN V+ 4 5 VL Logic 0 1 DG417 ON OFF DG418 OFF ON Logic "0" 0.8 V Logic "1" 2.4 V Top View DG419 Dual-In-Line and SOIC D 8 1 TRUTH TABLE DG419 S2 S1 2 7 V- GND 3 6 IN V+ 4 5 VL Logic SW1 SW2 0 ON OFF 1 OFF ON Logic "0" 0.8 V Logic "1" 2.4 V Top View * Pb containing terminations are not RoHS compliant, exemptions may apply Document Number: 70051 S10-1528-Rev.

Source/Drain Capacitances APPLICATIONS Switched Signal Powers Analog Switch The analog switch in Figure 10 derives power from its input signal, provided the input signal amplitude exceeds 4 V and its frequency exceeds 1 kHz. A positive input pulse turns on the clamping diode D1 and charges C1. The charge stored on C1 is used to power the chip; operation is satisfactory because the switch requires less than 1 µA of stand-by supply current. Loading of the signal source is imperceptible. The DG419’s on-resistance is a low 100  for a 5 V input signal. This circuit is useful when signals have to be routed to either of two remote loads. Only three conductors are required: one for the signal to be switched, one for the control signal and a common return.

D1 prevents current from leaking back towards the rest of the circuit. Current consumption by the CMOS analog switch is around 100 pA; this ensures that most of the power available is applied to the memory, where it is really needed. In the stand-by mode, hundreds of A are sufficient to retain memory data. The DG419, as shown in figure 11, allows accurate gain selection in a small package. Switching into virtual ground reduces distortion caused by RDS(on) variation as a function of analog signal amplitude. When the 5 V supply comes back up, the resistor divider senses the presence of at least 3.5 V, and causes a new change of state in the analog switch, restoring normal operation. GaAs FET Driver The DG419, as shown in figure 12 may be used as a GaAs FET driver. It translates a TTL control signal into - 8 V, 0 V level outputs to drive the gate.
