MAX428

19-2394; Rev 1; 7/97 Single/Dual/Quad High-Speed, Fast-Settling, High Output Current Operational Amplifier General Description The MAX408/428/448 are high speed general purpose monolithic operational amplifiers in a single, dual or quad package, that are useful for signal frequencies extending into the video range. These Op Amps function in gain configurations greater-than or equal-to 3. High output current allows large capacitive loads to be driven at high speeds. Open-loop voltage gain of 10k V/V and high slew rate of 90V/µs make the MAX408/428/448 ideal for analog amplification and high speed signal processing. 100MHz gain bandwidth and a ±0.1% settling time of l50ns make each amplifier ideal for fast data conversion systems. The amplifiers are capable of driving back terminated transmission lines of 75Ω with amplitudes of 5V peakto-peak. Along with the high speed and output drive capability, a 35nA offset current and trimmable offset voltage make the MAX408/428/448 optimal for signal conditioning applications where accuracy must be maintained. o Fast Settling Time: ±0.1% In 150ns o High Slew Rate: 90V/µs o Large Gain Bandwidth: 100MHz o Full Power Bandwidth: 4.8MHz at 6V p-p o Ease of Use: Internally Compensated for ACL ≥ 3 with 50°–60° Phase Margin o Low Supply Voltage Operation: ±4V o Wide Input Voltage Range: Within 1.5V of V+ and 0.5V of Vo Minimal Crosstalk: >90dB Separation (MAX428/448) o Short Circuit Protection Features MAX408/428/448 Applications Video Amplif...
