NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The TLC08x-Q1 devices features wide supply voltage range, high-output current drive in the order of 60 mA, low
input offset voltage, a high unity gain bandwidth 10 MHz and high slew of 16 V/µS. These features make the
device suitable in amplifying high-frequency and slew rate signals.
9.2 Typical Applications
9.2.1 TLC08x-Q1 Single-Supply Typical Application
Some applications require amplification of low amplitude and relatively high-frequency input signal. The sine
wave maximum slew rate is at zero crossing. The amplified signal distorts if the minimum slew rate is not met.
Operational amplifier slew rate must be higher than 2 × π × F × V, where F is the input signal frequency and V is
the output signal amplitude. TLC08x-Q1 Slew rate of 16 V/µS is capable of delivering an output signal of 2-V
peak and 1-MHz frequency with no distortion. See Figure 45 for an application curve that shows the results of
Figure 39.
