LMC6022 Low Power CMOS Dual Operational Amplifier
General Description
The LMC6022 is a CMOS dual 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 100k and 5 k loads) that is equal to or better than widely accepted bipolar equivalents, while the power supply requirement is less than 0.5 mW. This chip is built with National's advanced Double-Poly Silicon-Gate CMOS process. See the LMC6024 datasheet for a CMOS quad operational amplifier with these same features. n n n n n n Ultra low input bias current: 40 fA Input common-mode range includes V- Operating range from +5V to +15V supply Low distortion: 0.01% at 1 kHz Slew rate: 0.11 V/µs Micropower operation: 0.5 mW
