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 that of general-purpose BiFET
devices.
These devices use Texas instruments silicon-gate
LinCMOS technology, which provides offset
voltage stability far exceeding the stability
available with conventional metal-gate pro-
cesses.
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 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.
