Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The Texas Instruments TLV521DCKT is a dual general-purpose operational amplifier designed for high-precision, low-noise, low-power and low-voltage operation. This amplifier features high input impedance, low bias current, low input offset voltage and excellent common-mode rejection. The TLV521DCKT also provides fast settling time and very low distortion.

Application Fields

The TLV521DCKT is available in an 8-pin SOIC Packaged In a Tape and Reel format. This type of package allows this device to be used in many types of applications including medical, telecommunications, and automation. It is useful in such applications because of its small size, low power consumption and immunity to electrical noise. It is also suitable for high-performance instrumentation, precision measurement and control systems, analytical instruments, audio equipment, power supplies and many other analog devices.

Working Principle

The TLV521DCKT uses a hybrid configuration to provide a high-performance operational amplifier in a very small size. The amplifier consists of two input stages, an output stage and an error amplifier stage. The two input stages are the differential input stage and the common-mode input stage, which together provide the high input impedance and gain accuracy. The output stage consists of three stages, a gain stage, a current limiter, and a voltage-controlled buffer. The error amplifier stage is used to minimize offset voltage and improve thermal stability.

The TLV521DCKT features a low input offset voltage of 1.0 mV and a low input bias current of 0.10 uA, providing high accuracy when used in precision analog applications. It also offers high common-mode rejection, making it well-suited for use in multiplexed analog applications. The amplifier provides a typical output bandwidth of 1.2 MHz and a typical power-supply rejection ratio of 85dB.

The TLV521DCKT is a versatile operational amplifier, providing low-noise, low-power, precise and reliable performance for a variety of applications. Its small package size and fast slewing capabilities makes it ideal for a wide range of applications, from general-purpose to specialized design.
