description
The TLC27L4 and TLC27L9 quad operational
amplifiers combine a wide range of input offset
voltage grades with low offset voltage drift, high
input impedance, extremely low power, and high
gain.
These devices use Texas instruments silicon-gate
LinCMOSE 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 low-power consumption make
these cost-effective devices ideal for high-gain,
low- frequency, low-power applications. Four
offset voltage grades are available (C-suffix and
I-suffix types), ranging from the low-cost TLC27L4
(10 mV) to the high-precision TLC27L9 (900 mV).
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.
In general, many features associated with bipolar technology are available on LinCMOSE operational
amplifiers, without the power penalties of bipolar technology. General applications such as transducer
interfacing, analog calculations, amplifier blocks, active filters, and signal buffering are easily designed with the
TLC27L4 and TLC27L9. The devices also exhibit low voltage single-supply operation and ultra-low power
consumption, making them ideally suited for remote and inaccessible battery-powered applications. The
common-mode input voltage range includes the negative rail.
A wide range of packaging options is available, including small-outline and chip-carrier versions for high-density
system applications.
The device inputs and outputs are designed to withstand –100-mA surge currents without sustaining latch-up.
The TLC27L4 and TLC27L9 incorporate internal ESD-protection circuits that prevent functional failures at
voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2; however, care should be exercised in
handling these devices, as exposure to ESD may result in the degradation of the device parametric
performance.
The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized
for operation from –40°C to 85°C. The M-suffix devices are characterized for operation from –55°C to 125°C.
