TLC2652CP

TLC2652CP Description

The TLC2652CP from Texas Instruments is a high-precision, zero-drift operational amplifier designed for applications requiring ultra-low input offset voltage and minimal drift over time. Part of the LinCMOS™ series, this IC integrates chopper-stabilization technology to achieve exceptional DC accuracy (0.6 µV input offset) and near-zero drift, making it ideal for precision signal conditioning. Operating over a 3.8V to 16V supply range, it delivers a 1.9 MHz gain bandwidth product and 3.1V/µs slew rate, balancing speed with low power consumption (1.5mA supply current). Housed in an 8-pin DIP through-hole package, it is suited for prototyping and industrial environments.

TLC2652CP Features

• Zero-Drift Architecture: Eliminates 1/f noise and offset drift, ensuring long-term stability.
• Ultra-Low Input Bias Current (4 pA): Minimizes errors in high-impedance sensor interfaces.
• Wide Supply Range (3.8V–16V): Compatible with single- or dual-supply designs.
• High Output Drive (50 mA): Capable of driving heavy loads directly.
• RoHS3 Compliant & REACH Unaffected: Meets environmental and regulatory standards.
• Extended Temperature Range (0°C to 70°C): Reliable performance in industrial settings.

TLC2652CP Applications

• Precision Instrumentation: Weigh scales, medical devices, and data acquisition systems benefit from its low noise and drift.
• Sensor Signal Conditioning: Ideal for thermocouples, RTDs, and bridge sensors due to µV-level accuracy.
• Active Filters & Integrators: The 1.9 MHz GBW supports low-distortion audio and control systems.
• Automotive & Industrial Controls: Robust performance in harsh environments with wide voltage tolerance.
