The MAX4014/MAX4017/MAX4019/MAX4022 are precision, closed-loop, gain of +2 (or -1) buffers featuring high slew rates, high output current drive, and low differential gain and phase errors. These single-supply devices operate from +3.15V to +11V, or from ±1.575V to ±5.5V dual supplies. The input voltage range extends 100mV beyond the negative supply rail and the outputs swing Rail-to-Rail®. These devices require only 5.5mA of quiescent supply current while achieving a 200MHz -3dB bandwidth and a 600V/µs slew rate. In addition, the MAX4019 has a disable feature that reduces the supply current to 400µA. Input voltage noise for these parts is only 10nV/√Hz and input current noise is only 1.3pA/√Hz. This buffer family is ideal for low-power/low-voltage applications that require wide bandwidth, such as video, communications, and instrumentation systems. For space-sensitive applications, the MAX4014 comes in a tiny 5-pin SOT23 package.
The MAX4014, MAX4017, MAX4019 and MAX4022 are precision, closed‑loop buffers that provide a fixed gain of +2 (or –1) with rail‑to‑rail output swing. They operate from a single +3.15 V to +11 V supply or from dual ±1.575 V to ±5.5 V supplies, delivering up to 200 MHz –3 dB bandwidth and 600 V/µs slew rate while consuming only 5.5 mA quiescent current.
These devices are intended for portable, battery‑powered instruments, video line drivers, ADC interfaces, CCD imaging, and video routing systems. Features include internal precision resistors, low differential gain (0.04 %) and phase error (0.02°), high output drive (±120 mA), and a shutdown mode that reduces supply current to 400 µA. The datasheet provides detailed electrical characteristics, pin configurations, and layout recommendations for high‑frequency operation.
