_________________General Description

The MAX4214/MAX4215/MAX4217/MAX4219/MAX4222

are precision, closed-loop, gain of +2 (or -1) buffers

featuring high slew rates, high output current drive, and

low differential gain and phase error. They operate with

a single 3.15V to 11V supply or with ±1.575V to ±5.5V

dual supplies. The input common-mode voltage range

extends 100mV beyond the negative power-supply rail,

and the output swings Rail-to-Rail

These devices require only 5.5mA of quiescent supply

current while achieving a 230MHz -3dB bandwidth and

a 600V/µs slew rate. In addition, the MAX4215/

MAX4219 have a disable feature that reduces the sup-

ply current to 400µA per buffer. Input voltage noise is

only 10nV/√Hz, and input current noise is only

1.3pA/√Hz. This buffer family is ideal for low-power/low-

voltage applications requiring wide bandwidth, such as

video, communications, and instrumentation systems.

For space-sensitive applications, the MAX4214 comes

in a miniature 5-pin SOT23 package.

High-Speed, Single-Supply, Gain of 2, Closed-Loop, Rail-to-Rail Buffers with Enable The MAX4214/MAX4215/MAX4217/MAX4219/MAX4222 are single-supply, rail-to-rail output, voltage-feedback, closed-loop buffers that employ current-feedback techniques to achieve 600V/µs slew rates and 230MHz bandwidths. These buffers use internal 500Ω resistors to provide a preset closed-loop gain of 2V/V in the noninverting configuration or -1V/V in the inverting configuration.
PAGE 10
As the load resistance decreases, the useful input range is effectively limited by the output drive capability, since the buffers have a fixed voltage gain of 2V/V or -1V/V. For example, a 50Ω load can typically be driven from 40mV above VEE to 1.6V below VCC, or 40mV to 3.4V when operating from a single 5V supply. If the buffer is operated in the noninverting, gain of 2V/V configuration with the inverting input grounded, the useful input voltage range becomes 20mV to 1.7V instead of the -100mV to 2.
