TLC279IDR

The Texas Instruments TLC279IDR is a quad precision single supply operational amplifier designed for a wide range of applications. It offers 4 channels, enabling complex circuit designs. The device operates with a total supply voltage ranging from 3V to 16V, providing flexibility for various power requirements.

Key electrical characteristics include a typical gain bandwidth product of 1.7 MHz and a slew rate of 3.6 V/µs, suitable for moderate-speed signal processing. The input offset voltage is a maximum of 0.9 mV at 25°C, and the offset drift is typically 1.8 µV/°C, ensuring stable performance. With a typical input bias current of 60 pA, it is well-suited for applications requiring high input impedance.

The TLC279IDR features an architecture that allows the common-mode input voltage range to extend below the negative rail, and the output voltage range includes the negative rail. This characteristic is beneficial in single-supply applications. The device exhibits low noise, typically 10.8 nV/√Hz at 1 kHz, and a typical common-mode rejection ratio of 80 dB.

Available in SOIC and PDIP packages, the TLC279IDR is designed for operation within a temperature range of -40°C to 85°C. Its high input impedance, typically greater than 10¹² Ω, makes it suitable for sensitive signal amplification tasks.
