The MAX4219ESD+ is a high-speed, single supply, closed-loop rail to rail buffer with enable in 14 pin NSOIC package. This is precision, closed loop, gain of +2 (or -1) buffer featuring high slew rates, high output current drive and low differential gain and phase error. The input common mode voltage range extends 100mV beyond the negative power supply rail and the output swings rail to rail. It requires only 5.5mA of quiescent supply current while achieving a 230MHz -3dB bandwidth and a 600V/μs slew rate, input voltage noise is only 10nV/√Hz and input current noise is only 1.3pA/√Hz. Device also has a disable feature that reduces the supply current to 400μA per buffer. This buffer is ideal for low power/low voltage applications requiring wide bandwidth such as communications and instrumentation systems.
