Low-Cost, High-Speed, Single-Supply, Gain of +2
Buffers with Rail-to-Rail Outputs in SOT23
_______________General Description
The MAX4014/MAX4017/MAX4019/MAX4022 are preci-
sion, closed-loop, gain of +2 (or -1) buffers featuring
high slew rates, high output current drive, and low dif-
ferential 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or at any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.
