Low Power, Low Cost, Rail-to-Rail I/O Quad Amplifier



The CLC2011 (dual) and CLC4011 (quad) are ultra-low cost, low power, voltage feedback amplifiers. At 2.7V, the CLCx011 family uses only 136μA of supply current per amplifier and are designed to operate from a supply range of 2.5V to 5.5V (±1.25 to ±2.75). The input voltage range exceeds the negative and positive rails.
The CLCx011 family of amplifiers offer high bipolar performance at a low CMOS prices. They offer superior dynamic performance with 4.9MHz small signal bandwidths and 5.3V/μs slew rates. The combination of low power, high bandwidth, and rail-to-rail performance make the CLCx011 amplifiers well suited for battery-powered communication/computing systems.
