The TLC271CD is a low power programmable Op Amp (operational amplifier) manufactured by Texas Instruments. It is a dual, rail-to-rail input and output amplifier that is designed to operate from a single power supply. Its main features are a wide common-mode input range of -0.3V to VDD+0.3V, low input bias current, low power dissipation high gain, wide frequency response, and low offset voltage. Additionally, it has an industry-standard 8-pin plastic DIP package and wide operating temperature range of -40°C to 125°C, making it ideal for use in portable and handheld electronic products. The TLC271CD is most often used in analog circuits requiring low power, low voltage, and high precision in signal processing applications.
