6.1.1 Amplifier Topology

The topology chosen for the LMC603x, shown in Figure 6-1, is unconventional compared to general-purpose op amps. The LMC603x incorporates novel op-amp design that enables a wide input common-mode range and rail to rail output swing even when driving a large load. The input common-mode range includes ground, making the LMC603x an excellent choice for single-supply applications. While the LMC603x supports both a wide supply and common-mode voltage range, large input common-mode voltage can cause a degradation of input bias current performance.

The large signal voltage gain while sourcing is comparable to traditional bipolar op amps, even with a 600Ω load. The gain while sinking is greater than most CMOS op amps as a result of the additional gain stage; however, under heavy load (600Ω), the gain can be reduced as indicated in Section 5.6.
