TLC2254CN

TLC2254CN Description

The TLC2254CN from Texas Instruments is a general-purpose operational amplifier (op-amp) designed for precision analog applications. Part of the LinCMOS™ series, this quad-channel op-amp operates over a 4.4V to 16V supply range, making it suitable for both low-voltage and industrial-level designs. With a 210 kHz gain bandwidth product (GBW) and a 0.12V/µs slew rate, it balances speed and power efficiency, ideal for signal conditioning and filtering tasks. The device features an ultra-low input bias current of 1 pA and a 200 µV input offset voltage, ensuring high accuracy in sensitive measurements. Packaged in a 14-pin DIP (through-hole) tube, it is RoHS3 compliant and operates within a 0°C to 70°C temperature range.

TLC2254CN Features

• Low Power Consumption: Only 160µA per channel (640µA total for 4 channels), ideal for battery-powered systems.
• High Input Impedance: 1 pA input bias current minimizes loading effects in high-impedance sensor interfaces.
• Wide Supply Range: 4.4V to 16V supports diverse applications from portable devices to industrial systems.
• Robust Output Drive: 50 mA output current per channel enables direct driving of moderate loads.
• Low Noise & Offset: 200 µV offset voltage enhances precision in DC-coupled circuits.
• LinCMOS™ Technology: Combines CMOS low-power advantages with bipolar-like performance.

TLC2254CN Applications

• Sensor Signal Conditioning: Ideal for amplifying low-level signals from thermocouples, strain gauges, or photodiodes.
• Active Filters: Suitable for low-frequency (e.g., audio or instrumentation) filter designs due to its 210 kHz GBW.
• Portable & Battery-Powered Systems: Medical devices, handheld meters, and IoT sensors benefit from its low quiescent current.
• Industrial Control Systems: Reliable performance in 4-20mA loops, motor control feedback, and PLC interfaces.
• Test & Measurement Equipment: Precision voltage followers or integrators due to low input bias and offset.
