description

The TLC274x2 octal operational amplifier incorporates low offset-voltage drift, high input impedance, low noise, and speeds approaching that of general-purpose BiFET devices into a single package. This device uses Texas Instruments silicon-gate LinCMOS^TM

LinCMOS is a trademark of Texas Instruments Incorporated. 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 high slew rates make this a cost-effective device ideal for applications that have previously been reserved for BiFET and NFET products. These advantages, in combination with good common-mode rejection and supply-voltage rejection, make this device 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 LinCMOS^TM 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 TLC274x2. The device also exhibits low-voltage single-supply operation, making them ideally suited for remote and inaccessible battery-powered applications. The common-mode input voltage range includes the negative rail. The device inputs and outputs are designed to withstand -100-mA surge currents without sustaining latch-up.

^[dagger] The DB package is only available left-end taped and reeled.

The TLC274x2 incorporates internal ESD-protection circuits that prevent functional failures at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.2; however, exercise care in handling this device as exposure to ESD can result in the degradation of the device parametric performance.

The TLC274x2 is characterized for operation from 0°C to 70°C.
