CMOS LOW POWER OPERATIONAL AMPLIFIERS
Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free,
“Green" and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and
<1000ppm antimony compounds.
Description
The TLC27L1 operational amplifier combines a wide range of input
offset-voltage grades with low offset-voltage drift and high input
impedance. The TLC27L1 is a low-bias version of the TLC271
programmable amplifier.
Three offset-voltage grades are available, ranging from the low-cost
TLC27L1 (10mV) to the TLC27L1B (2mV) low-offset version. The
devices are offered in both commercial and industrial operating
temperature ranges.
The extremely high input impedance and low bias currents, in
conjunction 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.
The devices also exhibit low-voltage single-supply operation, with a
common-mode input-voltage range including the negative rail.

Applications
The TLC27L1 is the low power version of the TLC271. It offers low
power for applications requiring long battery life. For applications
that require more performance consider the TLC271.
The TLC27L1 is well suited to many consumer audio, industrial and
other low power applications. Consider carefully the bandwidth and
slew rate requirements for a specific application.
