19-0471; Rev 0; 2/96 250MHz, Broadcast-Quality, Low-Power Video Op Amps The MAX4102/MAX4103 op amps combine high-speed performance and ultra-low differential gain and phase while drawing only 5mA of supply current. The MAX4102 is compensated for unity-gain stability, while the MAX4103 is compensated for a closed-loop gain (AVCL) of 2V/V or greater. The MAX4102/MAX4103 deliver a 250MHz -3dB bandwidth (MAX4102) or a 180MHz -3dB bandwidth (MAX4103). Differential gain and phase are an ultra-low 0.002%/0.002° (MAX4102) and 0.008%/0.003° (MAX4103), making these amplifiers ideal for composite video applications. These high-speed op amps have a wide output voltage swing of ±3.4V (RL = 100Ω) and 80mA current-drive capability. ____________________________Features ♦ 250MHz -3dB Bandwidth (MAX4102) 180MHz -3dB Bandwidth (MAX4103) ♦ Unity-Gain Stable (MAX4102) ♦ 350V/µs Slew Rate ♦ Lowest Differential Gain/Phase (RL = 150Ω) MAX4102: 0.002%/0.002° MAX4103: 0.008%/0.003° ♦ Low Distortion (SFDR 5MHz): -78dBc ♦ 100dB Open-Loop Gain ♦ High Output Drive: 80mA ♦ Low Power: 5mA Supply Current ________________________Applications Broadcast and High-Definition TV Systems ______________Ordering Information Pulse/RF Amplifier PART ADC/DAC Amplifier MAX4102ESA MAX4103ESA ________Typical Application Circuit TEMP.

Not internally connected _______________Detailed Description The MAX4102/MAX4103 low-power, high-speed op amps feature ultra-low differential gain and phase, and are optimized for the highest quality video applications. Differential gain and phase errors are 0.002%/0.002° for the MAX4102 and 0.008%/0.003° for the MAX4103. The MAX4102 also features a -3dB bandwidth of over 250MHz and 0.1dB gain-flatness of 130MHz. The MAX4103 features a -3dB bandwidth of 180MHz and a 0.1dB bandwidth of 80MHz. The MAX4102 is unity-gain stable, and the MAX4103 is optimized for closed-loop gains of 2V/V (6dB) and higher. Both devices drive back-terminated 50Ω or 75Ω cables to ±3.1V (min) and deliver an output current of 80mA. Available in a small 8-pin SO package, the MAX4102/ MAX4103 are ideal for high-definition TV systems (in RGB, broadcast, or consumer video applications) that benefit from low power consumption and superior differential gain and phase characteristics. __________Applications Information Grounding, Bypassing, and PC Board Layout In order to achieve the full bandwidth, Microstrip and Stripline techniques are recommended in most cases. To ensure your PC board does not degrade the amp’s performance, it’s wise to design the board for a frequency greater than 1GHz. Even with very short runs, it’s good practice to use this technique at critical points, such as inputs and outputs. Whether you use a constant-impedance board or not, observe the following guidelines when designing the board: 8 • Do not use wire-wrap boards, because they are too inductive. • Do not use IC sockets. They increase parasitic capacitance and inductance. • In general, surface-mount components have shorter leads and lower parasitic reactance, and give better high-frequency performance than through-hole components. • The PC board should have at least two layers, with one side a signal layer and the other a ground plane. • Keep signal lines as short and as straight as possible. Do not make 90° turns; round all corners. • The ground plane should be as free from voids as possible. On Maxim’s evaluation kit, the ground plane has been removed from areas where keeping the trace capacitance to a minimum is more important than maintaining ground continuity. For example, the ground plane has been removed from beneath the IC to minimize pin capacitance. The bypass capacitors should include a 0.1µF at each supply pin and the ground plane, located as close to the package as possible. Then place a 10µF to 15µF lowESR tantalum at the point of entry (to the PC board) of the power-supply pins. The power-supply trace should lead directly from the tantalum capacitor to the VCC and VEE pins to maintain the low differential gain and phase of these devices. Setting Gain The MAX4102/MAX4103 are voltage-feedback op amps that can be configured as an inverting or noninverting gain block, as shown in Figures 1a and 1b. The gain is determined by the ratio of two resistors and does not affect amplifier frequency compensation. In the unity-gain configuration (Figure 1c), maximum bandwidth and stability are achieved with the MAX4102 when a small feedback resistor is included. This resistor suppresses the negative effects of parasitic inductance and capacitance. A value of 24Ω provides the best combination of wide bandwidth, low peaking, and fast settling time. In addition, this resistor reduces the errors from input bias currents. Choosing Resistor Values The values of feedback and input resistors used in the inverting or noninverting gain configurations are not critical (as is the case with current-feedback amplifiers), but should be kept small and noninductive. _______________________________________________________________________________________ 250MHz, Broadcast-Quality, Low-Power Video Op Amps RG VIN RF RT VOUT MAX4100 MAX4102 MAX4101 MAX4103 Table 1.

RT is calculated for 50Ω systems. VOUT = -(RF / RG)VIN Figure 1a. Inverting Gain Configuration RG MAX4102/MAX4103 The input capacitance of the MAX4102/MAX4103 is approximately 2pF. In either the inverting or noninverting configuration, the bandwidth limit caused by the package capacitance and resistor time constant is f3dB = 1 / (2Π RC), where R is the parallel combination of the input and feedback resistors (R F and R G in Figure 2) and C is the package and board capacitance at the inverting input. RS1 and RS2 represent the input termination resistors. Table 1 shows the typical bandwidth and resistor values for several gain configurations. Resistor Types RF VOUT MAX4100 MAX4102 MAX4101 MAX4103 Surface-mount resistors are the best choice for highfrequency circuits. They are of similar material to the metal-film resistors, but are deposited using a thick-film process in a flat, linear manner so that inductance is minimized. Their small size and lack of leads also minimize parasitic inductance and capacitance, thereby yielding more predictable performance. VIN VOUT = [1 + (RF / RG)]VIN RT RG VIN Figure 1b.

The MAX4102/ MAX4103 can typically drive 5pF and 20pF, respectively. Figure 3a illustrates how a capacitive load influences the amplifier’s peaking without an isolation resistor (R S). Figure 3b shows how an isolation resistor decreases the amplifier’s peaking. By using a small isolation resistor between the amplifier output and the load, large capacitance values may be driven without oscillation (Figure 4a). In most cases, less than 50Ω is sufficient. Use Figure 4b to determine the value needed in your application. Determine the worst-case maximum capacitive load you may encounter and select the appropriate resistor from the graph. 6 4 AVCL = +1 5 CL = 15pF RS = 22Ω 2 3 1 GAIN (dB) CL = 10pF 2 1 0 CL = 5pF -1 RS = 10Ω CL = 10pF 3 4 GAIN (dB) 0 -1 RS = 33Ω -2 -3 -2 -4 -3 -5 -4 -6 0.1M 1M 10M 100M 1G 0.1M 1M FREQUENCY (Hz) 10M 100M 1G FREQUENCY (Hz) Figure 3b.
