description
The TLC272 and TLC277 precision dual
operational amplifiers combine a wide range of
input offset voltage grades with low offset voltage
drift, high input impedance, low noise, and speeds
approaching those of general-purpose BiFET
devices.
These devices use Texas Instruments silicongate
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 costeffective
devices ideal for applications previously
reserved for BiFET and NFET products. Four
offset voltage grades are available (C-suffix and
I-suffix types), ranging from the low-cost TLC272
(10 mV) to the high-precision TLC277 (500 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.
