The LMV3XX family is fabricated on a CMOS process, features a rail-to-rail output, and is unity gain stable. The typical non-inverting circuit schematic is shown in +Vs - Figure 2: Typical Topology for driving a capacitive load Out LMV3XX - Rf Rg Magnitude (dB) + 2k 10k + 0.01F CL 10k 6.8F +In Rs LMV3XX 3 2 1 0 -1 -2 -3 -4 -5 -6 -7 -8 -9 CL = 50pF Rs = 0 CL = 100pF Rs = 400 CL = 200pF Rs = 450 0.01 0.1 1 10 Frequency (M H z ) Figure 1. Figure 1: Typical Non-inverting configuration Power Dissipation The maximum internal power dissipation allowed is directly related to the maximum junction temperature. If the maximum junction temperature exceeds 150C, some performance degradation will occur. If the maximum junction temperature exceeds 175C for an extended time, device failure may occur. Driving Capacitive Loads The Frequency Response vs CL plot on page 4, illustrates the response of the LMV3XX family. A small series resistance (Rs) at the output of the amplifier, illustrated in Figure 2, will improve stability and settling performance. Rs values in the Frequency Response vs CL plot were chosen to achieve maximum bandwidth with less than 1dB of peaking. For maximum flatness, use a larger Rs. As the plot indicates, the LMV3XX family can easily drive a 200pF capacitive load without a series resistance. For comparison, the plot also shows the LMV321 driving a 200pF load with a 225 series resistance. Figure 3: Frequency Response vs CL for unity gain configuration Layout Considerations General layout and supply bypassing play major roles in high frequency performance. Fairchild has evaluation boards to use as a guide for high frequency layout and as aid in device testing and characterization. Follow the steps below as a basis for high frequency layout: * Include 6.8F and 0.01F ceramic capacitors * Place the 6.8F capacitor within 0.75 inches of the power pin * Place the 0.01F capacitor within 0.1 inches of the power pin * Remove the ground plane under and around the part, especially near the input and output pins to reduce parasitic capacitance * Minimize all trace lengths to reduce series inductances Refer to the evaluation board layouts shown in Figure 5 on page 8 for more information. Driving a capacitive load introduces phase-lag into the output signal, which reduces phase margin in the amplifier. The unity gain follower is the most sensitive configuration. In a unity gain follower configuration, the LMV3XX family requires a 450 series resistor to drive a 200pF load. The response is illustrated in Figure 3.
