General Description
136μA supply current
ꢀ■
4.9MHz bandwidth
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.

5.3V/μs slew rate
21nV/√Hz input voltage noise
35mA linear output current
Fully specified at 2.7V and 5V supplies
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.
