Built on TI's advanced CMOS process, it achieves performance levels typically associated with bipolar amplifiers, including 126 dB open-loop voltage gain and low 22 nV\/sqrt(Hz) voltage noise. The rail-to-rail output swing and input common-mode range that includes ground enable true single-supply operation without signal clipping. With ultra-low input bias current of 2 fA, the LMC660 is particularly suited for high-impedance source applications such as photodiode amplifiers and pH electrode interfaces.","working_principle":"The LMC660 employs a CMOS input stage that provides extremely low input bias current (2 fA typical) due to the gate insulation of the input MOSFETs. The input stage common-mode range extends to the negative rail (ground in single-supply operation), enabling direct ground-referenced signal processing. The output stage uses a complementary PMOS\/NMOS push-pull configuration to achieve rail-to-rail output swing. Internal compensation ensures stability in unity-gain configurations. The low quiescent current of 400 \u00b5A per amplifier (independent of supply voltage) makes the device suitable for battery-powered applications while maintaining 1.4 MHz gain-bandwidth product.","pin_description":"\n
