TS321AIYLT is a low noise, rail-to-rail, single supply voltage feedback-input amplifier capable of delivering up to ±2mA of output current; it is classed as a linear amplifier in the instrumentation, OP amps, buffer amplifier category.

Linear amplifiers amplify a signal without altering its shape. This is in contrast to non-linear amplifiers which may introduce distortion. Instrumentation amplifiers are a type of linear amplifier which amplifies a small differential signal (the difference between two or more signals) and blocks any signals common to both inputs. This type of amplifier was developed for use in measuring instruments and medical equipment.

Operational amplifiers (Op Amps) are high gain, direct coupling devices with a differential input and single ended output. They are used in most analog systems to build gain blocks, filters, and comparators among other applications. Buffer amplifiers are usually active, low-impedance devices with high-input impedance and low-output impedance. They are used to provide electrical isolation and protection between two circuits, preventing one circuit from loading down the other.

The TS321AIYLT combines all of these features with a wide operating voltage range and low power consumption to create an extremely low noise, rail-to-rail, single supply voltage feedback-input amplifier. Its versatile ability to deliver up to ±2mA of output current lets it be used in a variety of applications, from medical devices to audio systems.

This particular amplifier is designed for low noise operation. Its noise performance is characterized by a typical voltage noise density of 13 nV/√Hz and a typical current noise density of 1.2 pA/√Hz. This enables it to amplify low strength signals without introducing significant distortion.

The TS321AIYLT is a single supply device, meaning it requires only one voltage, as opposed to dual supply amplifiers which require two. This makes it easier to integrate into existing systems. It also has a wide operating voltage range, from 4.5V to 36V, making it suitable for a range of application areas.

The device is able to deliver up to ±2mA of output current with a wide common-mode voltage range and a low quiescent current (15µA). This makes it ideal for several applications, including current sensing, transimpedance amplification, low power audio, motion sensing and low power system level offset correction.

The device incorporates both internal compensation circuitry and input feedback to ensure stability and accuracy. This ensures that the amplifier is able to accurately amplify low strength signals without introducing significant distortion. The device is protected by current limiting, ensuring that it is not damaged if the input signal is too strong.

The TS321AIYLT is an extremely low noise, rail-to-rail, single supply voltage feedback-input amplifier with a wide operating voltage range, low power consumption, and the ability to deliver up to ±2mA of output current. It is an ideal device for medical devices, audio systems, current sensing, transimpedance amplification, low power audio, motion sensing and low power system level offset correction.
