CLC415 Quad, Wideband Monolithic Op Amp General Description Features The CLC415 is a wideband, quad, monolithic operational amplifier designed for intermediate gain applications where power and cost per channel of are primary concern. Benefiting from National’s current feedback architecture, the CLC415 offers a gain range of ± 1 to ± 10 while providing stable, oscillation free operation without external compensation, even at unity gain. Operating from ± 5V supplies, the CLC415 consumes only 50mW of power per channel, yet maintains a 160MHz small-signal bandwidth and a 1500V/µs slew rate. High density applications requiring an integrated solution will enjoy the CLC415’s 70dB channel isolation (input referred @ 5MHz). With its exceptional differential gain and phase, typically 0.03% and 0.03˚ @ 3.58MHz, the CLC415 is designed to meet the performance and cost per channel requirements of high volume composite video applications. The CLC415’s large-signal bandwidth, high slew rate and high drive capability are features well suited for RGB-video applications. The CLC415 is a quad version of the high speed CLC406 while the CLC414 is a lower power quad version of the same. Both of these quads afford the designer lower power consumption and lower cost per channel with the additional benefit of requiring less board space per amplifier. Constructed using an advanced, complementary bipolar process and National’s proven current feedback architectures. The CLC415 is available in several versions to meet a variety of requirements. Enhanced Solutions (Military/Aerospace) SMD Number: 5962-93055 Space level versions also available.

The loop gain and frequency response for a current feedback op amp is predominantly set by the feedback resistor value. The CLC415 is optimized for a gain of +6 to use a 500Ω feedback resistor (use a 900Ω Rf for maximally flat response at a gain of +2). Using lower values can lead to excessive ringing in the pulse response while higher value will limit the bandwidth. Application Note OA-13 provides a more detailed discussion of choosing a feedback resistor. The equations found in this application note are to be considered a starting point for the determination of Rf at any gain. The value of input impedance for the CLC415 is approximately 60Ω. These equations do not account for parasitic capacitance at the inverting input nor across Rf. The plot found below entitled “Recommended Rf vs. Gain” offers values of Rf which will optimize the frequency response of the CLC415 over its ± 1 to ± 10 gain range. Unlike voltage feedback, current feedback op amps require a non-zero Rf for unity gain followers. For best operation, the DC source impedance looking out of the non-inverting input should be less than 3kΩ but greater than 20Ω. Parasitic self oscillations may occur in the input transistors if the DC source impedance is out of this range. This impedance also acts as the gain for the non-inverting input bias and noise currents and therefore can become troublesome for high values of DC source impedance. The inverting configuration of Figure 3 shows a 25Ω resistor to ground on the non-inverting input which insures stability but does not provide bias current cancellation. The input bias currents are unrelated for a current feedback amplifier which eliminates the need for source impedance matching to achieve bias current cancellation. DS012751-17 FIGURE 3. Recommended Inverting Gain Circuit DC Accuracy and Noise Please refer to the application information section of the CLC406 for a discussion of output offset voltage and spot noise calculation. Crosstalk In any multi-channel integrated circuit there is an undesirable tendency for the signal in one channel to couple with and reproduce itself in the output of another channel. This effect is referred to as crosstalk. Crosstalk is expressed as channel separation or channel isolation which indicates the magnitude of this undesirable effect. This effect is measured by driving one or more channels and observing the output of the other undriven channel(s). The CLC415 plot page offers two different graphs detailing the effect of crosstalk over frequency. One plot entitled “All-Hostile Crosstalk Isolation” graphs all-hostile, input referred crosstalk. All-hostile crosstalk refers to the condition where three channels are driven simultaneously while observing the output of the undriven fourth channel. Input-referred implies that crosstalk is directly affected by gain and therefore a higher gain increases the crosstalk effect by a factor equal to that gain setting. The plot entitled “Most Susceptible Channel-to-Channel Pulse Coupling” describes the effect of crosstalk when one channel is driven with a 2VPP pulse while the output of the most effected channel is observed. DS012751-19 FIGURE 1. Recommended Rf vs. Gain DS012751-16 FIGURE 2. Recommended Non-Inverting Gain Circuit www.national.com 8 ticular importance is the careful control of parasitic capacitances on the output pin. As the output impedance plot shows, the closed loop output for the CLC415 eventually becomes inductive as the loop gain rolls off with increasing frequency. Direct capacitive loading on the output pin can quickly lead to peaking in the frequency response, overshoot in the pulse response, ringing or even sustained oscillations. The “Settling Time vs. Capacitive Load” plot should be used as a starting point for the selection of a series output resistor when a capacitive load must be driven. A quad amplifier will require careful attention to signal routing in order to minimize the effects of crosstalk. Signal coupling through the power supplies can be reduced with bypass capacitors placed close to the device supply pins. Evaluation Board Evaluation PC boards (part number CLC730024 for through-hole and 730031 for SOIC) for the CLC415 are available. (Continued) Unused Amplifiers It is recommended that any unused amplifiers in the quad package be connected as unity gain followers (Rf =500Ω) with the non-inverting input tied to ground through a 50Ω resistor. Slew Rate and Harmonic Distortion Please see the application information for the CLC406. Differential Gain and Phase Differential gain and phase performance specifications are common to composite video distribution applications. These specifications refer to the change in small signal gain and phase of the color subcarrier frequency (4.43MHz for PAL composite video) as the amplifier output is swept over a range of DC voltages. Application Note OA-08 provides an additional discussion of differential gain and phase measurements. Printed Circuit Layout As with any high speed component, a careful attention to the board layout is necessary for optimum performance.
