TS2158A is a General Purpose Amplifier SOT23-5 RoHS manufactured by Trusignal Microelec. It consists of five SOT23 packages and uses a single rail voltage ranging from -2.7V to 15V and a 5V reference voltage. The amplifier is designed for wide bandwidth for both AC and DC applications, exhibiting low-noise and low distortion properties. It features an overall gain accuracy of ±2% and a power supply rejection ratio of 70dB. The amplifier also provides a very high slew rate of 33V/µs, helping to ensure excellent signal-to-noise performance. This makes it suitable for use in applications such as low noise environmental monitor systems, video amplifiers, instrumentation amplifiers, and professional audio systems.
