Product Description
The STMicroelectronics TS921IDT is a single rail-to-rail operational amplifier designed for demanding electronic applications that require high output drive, low noise, and precision performance in a compact form factor.
Packaged in an 8-pin SOIC for easy surface-mount integration, it operates within a broad supply voltage range from 2.7V to 12V. This flexibility makes it ideal for both battery-powered and high-voltage industrial systems. The device delivers a gain bandwidth product of 4 MHz and a slew rate of 1.3 V/μs, enabling high-speed signal processing and low distortion for high-quality audio and instrumentation circuits.
With a maximum output current of 80 mA, the TS921IDT can efficiently drive low impedance loads, including those used in audio amplifiers or sensor interfaces. Its rail-to-rail input and output architecture ensure maximum dynamic range, while very low input noise (9 nV/√Hz) and offset (5 mV) help maintain signal purity for precision measurement and communication systems.
The amplifier is engineered for reliability and robustness with latch-up immunity and ESD protection of 1.5 kV, safeguarding sensitive electronic implementations. The SOIC package measures just 9.8 mm by 7.1 mm with a height of 4.1 mm, allowing dense component layouts. Designed for stable capacitive loads up to 500 pF, it supports reliable operation even in complex circuit environments.
A temperature operating range from -40°C to +125°C ensures suitability across industrial, laboratory, and commercial environments. Internal BiCMOS architecture optimizes low power consumption and performance, making the TS921IDT ideal for modern electronics, manufacturing test setups, industrial control, audio processing, and signal conditioning.
