MAX4266

19-1552; Rev 0; 10/99 Ultra-Low-Distortion, Single-Supply, 300MHz Op Amps with Enable General Description The MAX4265–MAX4270 single-supply, voltage-feedback op amps are capable of driving a 100Ω load while maintaining ultra-low distortion over a wide bandwidth. They offer superior spurious-free dynamic range (SFDR) performance: -90dBc or better at frequencies below 5MHz and -60dBc at a 100MHz frequency. Additionally, input voltage noise density is 8nV/√Hz while operating from a single +4.5V to +8.0V supply or from dual ±2.25V to ±4.0V supplies. These features make the MAX4265–MAX4270 ideal for use in high-performance communications and signalprocessing applications that require low distortion and wide bandwidth. The MAX4265 single and MAX4268 dual unity-gain-stable amplifiers have up to a 300MHz gain-bandwidth product. The MAX4266 single and MAX4269 dual amplifiers have up to a 350MHz bandwidth at a minimum stable gain of +2V/V. The MAX4267 single and MAX4270 dual amplifiers have a 200MHz bandwidth at a minimum stable gain of +5V/V. For additional power savings, these amplifiers feature a low-power disable mode that reduces supply current to 1.6mA and places the outputs in a high-impedance state. The MAX4265/MAX4266/MAX4267 are available in a space-saving 8-pin µMAX package, and the MAX4268/ MAX4269/MAX4270 are available in a 16-pin QSOP package. o Superior SFDR with 100Ω Load -90dBc (fC = 5MHz ) -60dBc (fC = 100MHz) o 35dBm IP3 (fC = 20MHz) o 8nV/√Hz Voltage Noise Density ...
