Rail-to-Rail Input Stage  
The AS1713 CMOS op amps have parallel connected n- and p-channel differential input stages that combine to accept  
a common-mode range extending to both supply rails. The n-channel stage is active for common-mode input voltages  
typically greater than (VSS + 1.2V), and the p-channel stage is active for common-mode input voltages typically less  
than (VDD - 1.2V).  
Rail-to-Rail Output Stage  
The minimum output is within millivolts of ground for single- supply operation, where the load is referenced to ground  
(VSS). Figure 26 shows the input voltage range and the output voltage swing of an AS1713 connected as a voltage fol-  
lower. The maximum output voltage swing is load dependent although it is guaranteed to be within 500mV of the posi-  
tive rail (VDD = 2.7V) even with maximum load (32Ω to ground) as shown in Figure 27.
