TSV992AID

TSV992AID Application Field and Working Principle

The TSV992AID is an advanced linear amplifier from ST Microelectronics specifically designed to provide voltage and current amplification for instrumentation, operational amplifiers (OP amps), and buffer amplifiers. It is a wide bandwidth dual amplifier available in a 28-pin VSSOP package which allows development of fully integrated, low power, high precision instrumentation systems.

The TSV992AID is a dual gain-setable rail-to-rail output instrumentation amplifier (IA) with rail-to-rail inputs. The amplifier provides up to 2 A of peak output current while delivering wide bandwidth and low distortion. It features an integrated precision amplifier core with gain programmable using an external capacitor or a three-pin serial interface. The fully differential input stage and the voltage comparator of the amplifier provide low noise electrical performance.

The TSV992AID has a wide supply voltage range of 2.7V to 5.5V and can operate from a single-supply voltage. It uses a low power BiCMOS technology that makes it suitable for low power applications as well. Its PGA (Programmable Gain Amplifier) provides accuracy and a wide neat range, and its temperature compensation ensures stability.

Input Characteristics

The TSV992AID has a wide differential input voltage range of 0.15V to the rails. It provides internal linearization and filters out small input signals which are below the offset voltage. The device also includes an offset compensation circuit which provides a higher level of accuracy than other types of amplifiers.

Output Characteristics

The TSV992AID features rail-to-rail output operation with a peak current of up to 2 A and a slew rate capability of 20V/μs. The amplifier supports a wide output voltage range of 1.5V to the rails, and its low distortion and high speed make it suitable for use in demanding audio applications.

Gain Setting Characteristics

The amplifiers gain is programmable via an external capacitor or a three-pin serial interface. It also has adjustable offset and gain drift compensation. The device can be programmed to provide gains from unity gain to 50dB.

Applications

The TSV992AID can be used for high-accuracy, low power instrumentation systems, buffer amplifiers, and operational amplifiers. Its wide bandwidth, low noise performance and rail-to-rail capability make it ideal for use in medical instrumentation, high-precision industrial measurement systems, telecom/datacom, automotive applications, and consumer electronics. The device is also suitable for use in high-end, mobile phone audio and active filter applications.
