OP Amps, Buffer Amps ICs

TS954ID Description

The TS954ID from STMicroelectronics is a general-purpose quad operational amplifier designed for automotive-grade applications. Packaged in a 14-pin SOIC tube, this IC integrates four independent op-amps with a wide supply voltage range (2.7V to 12V), making it versatile for both low-voltage and moderate-power systems. Despite being obsolete, it remains a reliable choice for legacy designs due to its low input bias current (35nA), moderate gain bandwidth (3MHz), and slew rate of 1V/µs. Its ROHS3 compliance and REACH-unaffected status ensure adherence to environmental regulations.

TS954ID Features

• Automotive-Grade Reliability: Meets stringent automotive standards for durability.
• Low Power Consumption: 950µA total supply current (per quad channel) for energy-efficient designs.
• Wide Supply Range: Operates from 2.7V to 12V, suitable for battery-powered and industrial systems.
• Balanced Performance: 6mV input offset voltage and 10mA output current per channel ensure stable signal conditioning.
• Surface-Mount Design: 14-SOIC package enables compact PCB layouts.
• Low Noise: 35nA input bias current minimizes error in high-impedance circuits.

TS954ID Applications

• Sensor Signal Conditioning: Ideal for amplifying low-level signals from pressure sensors, thermocouples, or strain gauges.
• Automotive Electronics: Used in ECUs, infotainment systems, and battery management due to its rugged design.
• Portable Devices: Fits battery-operated equipment (e.g., medical monitors, handheld meters) thanks to its low-voltage operation.
• Active Filters & Buffers: Suitable for audio preamps, anti-aliasing filters, and impedance matching.
• Legacy System Maintenance: A dependable replacement for obsolete op-amp designs requiring quad-channel functionality.

Conclusion of TS954ID

The TS954ID offers a cost-effective, robust solution for general-purpose amplification in automotive and industrial systems. While marked obsolete, its low noise, wide voltage range, and quad-channel integration make it a pragmatic choice for existing designs or niche applications. Engineers seeking a proven, compliant op-amp with moderate bandwidth and low power will find it well-suited for signal processing, filtering, and sensor interfacing.
