The LMC6024 is a CMOS quad operational amplifier which can operate from either a single supply or dual supplies. Its performance features include an input common-mode range that reaches V−, low input bias current and voltage gain (into 100 kΩ and 5 kΩ loads) that is equal to or better than widely accepted bipolar equivalents, while the power supply requirement is less than 1 mW. This chip is built with Texas Instrument's advanced Double-Poly Silicon-Gate CMOS process. See the LMC6022 datasheet for a CMOS dual operational amplifier with these same features.
