PIN FUNCTIONS  
should be connected to the ground plane (Figure 1). For  
singlesupplyoperation,theAGNDpinshouldbebypassed  
to the ground plane with at least a 0.1µF capacitor (at least  
1µF for best AC performance) (Figure 2).  
Shutdown (SHDN): When the SHDN input goes high or is  
open-circuited, the LTC1562-2 enters a “zero-power”  
shutdown state and only junction leakage currents flow.  
The AGND pin and the amplifier outputs (see Figure 3)  
assume a high impedance state and the amplifiers effec-  
tively disappear from the circuit. (If an input signal is  
applied to a complete filter circuit while the LTC1562-2 is  
in shutdown, some signal will normally flow to the output  
throughpassivecomponentsaroundtheinactiveopamps.)

A small pull-up current source at the SHDN input defaults  
theLTC1562-2totheshutdownstateiftheSHDNpinisleft  
floating. Therefore, the user must connect the SHDN pin  
to a logic “low” (0V for ±5V supplies, V– for 5V total  
supply) for normal operation of the LTC1562-2. (This  
conventionpermitstrue“zero-power”shutdownsincenot  
even the driving logic must deliver current while the part  
is in shutdown.) With a single supply voltage, use V– for  
logic “low,” do not connect SHDN to the AGND pin.
