description  
NC – No internal connection  
The TLC274 and TLC279 quad operational  
amplifiers combine a wide range of input offset  
voltage grades with low offset voltage drift, high  
input impedance, low noise, and speeds  
approaching that of general-purpose BiFET  
devices.

These devices use Texas Instruments  
N Package  
silicon-gate LinCMOS  
technology, which  
provides offset voltage stability far exceeding the  
stability available with conventional metal-gate  
processes.  
The extremely high input impedance, low bias  
currents, and high slew rates make these  
cost-effective devices ideal for applications which  
have previously been reserved for BiFET and  
NFET products. Four offset voltage grades are  
available (C-suffix and I-suffix types), ranging  
from the low-cost TLC274 (10 mV) to the high-  
precision TLC279 (900 µV). These advantages, in  
combination with good common-mode rejection  
and supply voltage rejection, make these devices  
a good choice for new state-of-the-art designs as  
well as for upgrading existing designs.
