• See AN-1112 (Literature Number SNVA009) for

at supply voltages below its ensured 2.7V operation.

DSBGA Considerations

This provides a “comfort zone” for adequate operation

at voltages significantly below 2.7V. Its ultra low input

currents (I

) makes it well suited for low power active

filter application, because it allows the use of higher

resistor values and lower capacitor values. In

addition, the drive capability of the LMC6035/6 gives

these op amps a broad range of applications for low

voltage systems.

A desirable feature that the LMC6035/6 brings to low voltage applications is its output drive capability—a hallmark for TI's CMOS amplifiers. The circuit of Figure 43 illustrates the drive capability of the LMC6035/6 at 3V of supply.

Output Swing Performance of Benchmark Op Amp per the Circuit of Figure 43 Notice the superior drive capability of LMC6035 when compared with the benchmark measurement—even though the benchmark op amp uses twice the supply current.

LMC6035, LMC6035-Q1, LMC6036 SNOS875G – JANUARY 2000 – REVISED APRIL 2013 www.ti.com Not only does the LMC6035/6 provide excellent output swing capability at low supply voltages, it also maintains high open loop gain (A VOL) with heavy loads. To illustrate this, the LMC6035 and the benchmark op amp were compared for their distortion performance in the circuit of Figure 43. The graph of Figure 46 shows this comparison.

First determine the frequency scaling factor (FSF) for the desired cutoff frequency. Choosing fc at 3kHz, provides the following FSF computation: – FSF = 2π x 3kHz (desired cutoff freq.) = 18.84 x 10 3 2.

First choose a center frequency (fc). Figure 49 represents component values that were obtained from the following computation for a center frequency of 1kHz. R2 = R3 = 1/(2 πf cC) Given: fc = 1kHz and C R2 = R3 = 1/(2π x 3kHz x 6.8nF) = 23.4kΩ (chosen) = 6.

LMC6035, LMC6035-Q1, LMC6036 SNOS875G – JANUARY 2000 – REVISED APRIL 2013 www.ti.com The load capacitance interacts with the op amp's output resistance to create an additional pole. If this pole frequency is sufficiently low, it will degrade the op amp's phase margin so that the amplifier is no longer stable at low gains.
