740MHz、低噪声、低失真运算放大器,SOT23-5封装

产品详情

The MAX4104/MAX4105/MAX4304/MAX4305 op amps feature ultra-high speed, low noise, and low distortion in a SOT23 package. The unity-gain-stable MAX4104 requires only 20mA of supply current while delivering 625MHz bandwidth and 400V/µs slew rate. The MAX4304, compensated for gains of +2V/V or greater, delivers a 730MHz bandwidth and a 1000V/µs slew rate. The MAX4105 is compensated for a minimum gain of +5V/V and delivers a 410MHz bandwidth and a 1400V/µs slew rate. The MAX4305 has +10V/V minimum gain compensation and delivers a 340MHz bandwidth and a 1400V/µs slew rate.

Low voltage noise density of 2.1nV/√Hz and -88dBc spurious-free dynamic range make these devices ideal for low-noise/low-distortion video and telecommunications applications. These op amps also feature a wide output voltage swing of ±3.7V and ±70mA output current- drive capability. For space-critical applications, they are available in a miniature 5-pin SOT23 package.

描述

The MAX4104 evaluation kit (EV kit) simplifies evaluation of the MAX4104 ultra-high-speed, low-noise, 880MHz amplifier. The EV kit circuit demonstrates the MAX4104 in the noninverting unity-gain configuration. RF-style connectors (SMA) and 50Ω terminating resistors are included for test equipment compatibility.

The MAX4104 EV kit can also be used to evaluate the MAX4105, MAX4304, and MAX4305. Simply order a free sample of the appropriate part (MAX4105ESA, MAX4304ESA, or MAX4305ESA), replace the IC on the EV board, and change the gain-setting resistors for the desired gain. Refer to the MAX4104/MAX4105/MAX4304/MAX4305 data sheet for suggested resistor values.
