FEATURES

DESCRIPTION

Ultra-low power consumption and low input-leakage

• Low Supply Current: 14 μA (Typ)

current are the hallmarks of the LMC6041. Providing

• Operates from 4.5V to 15.5V Single Supply

input currents of only 2 fA typical, the LMC6041 can

• Ultra Low Input Current: 2 fA (Typ)

operate from a single supply, has output swing

extending to each supply rail, and an input voltage

• Rail-to-Rail Output Swing

range that includes ground.

• Input Common-Mode Range Includes Ground

The LMC6041 is ideal for use in systems requiring

ultra-low power consumption. In addition, the

LMC6041 SNOS610E – DECEMBER 1994 – REVISED MARCH 2013 www.ti.com APPLICATIONS HINTS AMPLIFIER TOPOLOGY The LMC6041 incorporates a novel op-amp design topology that enables it to maintain rail-to-rail output swing even when driving a large load. Instead of relying on a push-pull unity gain output buffer stage, the output stage is taken directly from the internal integrator, which provides both low output impedance and large gain.

LMC6041 Noninverting Gain of 10 Amplifier, Compensated to Handle Capacitive Loads In the circuit of Figure 29, R1 and C1 serve to counteract the loss of phase margin by feeding the high frequency component of the output signal back to the amplifier's inverting input, thereby preserving phase margin in the overall feedback loop. Capacitive load driving capability is enhanced by using a pull up resistor to V+ (Figure 30 ).
