TS925ID

TS925ID Description

The TS925ID by STMicroelectronics is a general-purpose quad operational amplifier (op-amp) housed in a 16-pin SOIC package. Designed for precision analog applications, it operates over a wide supply voltage range of 2.7V to 12V, making it versatile for both low-voltage and moderate-voltage systems. With a gain bandwidth product of 4 MHz and a slew rate of 1.3V/µs, it delivers stable performance in signal conditioning, filtering, and amplification tasks. The device features low input bias current (15 nA) and moderate input offset voltage (3 mV), ensuring accuracy in sensitive circuits. Though marked obsolete, it remains a reliable choice for legacy designs due to its ROHS3 compliance and REACH unaffected status.

TS925ID Features

• Quad op-amp configuration: Integrates four independent amplifiers in a single package, saving board space.
• Wide supply range (2.7V–12V): Suitable for battery-powered and industrial applications.
• Low power consumption: Draws 6mA supply current, ideal for energy-efficient designs.
• High output drive (80mA/channel): Capable of driving heavy loads, such as small motors or LEDs.
• Low noise and distortion: Ensures clean signal amplification in audio and sensor interfaces.
• Surface-mount (SOIC-16) package: Facilitates compact PCB layouts and automated assembly.

TS925ID Applications

The TS925ID excels in:

• Portable electronics: Power-sensitive devices like medical sensors or handheld instruments.
• Active filters and signal conditioning: Precision analog front-ends for data acquisition systems.
• Audio amplification: Preamplifiers and tone control circuits due to its low-noise characteristics.
• Industrial control systems: Analog PID controllers or transducer interfaces requiring robust performance.
• Legacy equipment maintenance: Replacing older op-amps in existing designs without layout changes.

Conclusion of TS925ID

While the TS925ID is obsolete, its balanced performance, low power consumption, and high integration make it a pragmatic choice for engineers maintaining or upgrading older systems. Its 4 MHz bandwidth and 80mA output drive provide a cost-effective solution for medium-speed analog tasks, though newer alternatives may offer improved specs for cutting-edge designs. For legacy-compatible, space-constrained applications, the TS925ID remains a technically viable option.
