Texas Instruments LMC603x/LMC6035-Q1 Low-Power CMOS Op Amps

Texas Instruments LMC603x/LMC6035-Q1 Low-Power CMOS Operational Amplifiers (Op Amps) are economical, low-voltage op amps capable of rail-to-rail output swing into loads of 600Ω. The LMC6035 is available in a chip-sized package (8-bump DSBGA) using micro SMD package technology. Both devices allow for single-supply operation and are specified for 2.7V, 3V, 5V, and 15V supply voltage. The 2.7V supply voltage corresponds to the end-of-life voltage (0.9V/cell) for three NiCd or NiMH batteries in series, making the LMC603x/LMC6035-Q1 an excellent choice for portable and rechargeable systems. These devices also feature a well-behaved decrease in specifications at supply voltages less than the specified 2.7V operation. This behavior provides a comfort zone for adequate operation at voltages significantly less than 2.7V. The ultra-low input current makes these devices an excellent choice for low-power, active-filter applications because a low-input bias current allows higher resistor and lower capacitor values. In addition, the drive capability of the LMC603x/LMC6035-Q1 makes these op amps an excellent choice in a broad range of applications for low-voltage systems. The Texas Instruments LMC6035-Q1 devices are AEC-Q100 qualified for automotive applications.
