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.
