Low-Cost, High-Speed, Single-Supply, Gain of +2
Buffers with Rail-to-Rail Outputs in SOT23
_______________General Description
____________________________Features
ꢀ Internal Precision Resistors for Closed-Loop
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 eꢀtends
100mV beyond the negative supply rail and the outputs
swing Rail-to-Rail®.
Gains of +2 or -1
ꢀ High Speed:
200MHz -3dB Bandwidth
30MHz 0.1dB Gain Flatness (6MHz min)
600V/µs Slew Rate
ꢀ Single 3.3V/5.0V Operation
ꢀ 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.
ꢀ Input Voltage Range Extends Beyond V
EE
ꢀ Low Differential Gain/Phase: 0.04%/0.02°
ꢀ Low Distortion at 5MHz:
-78dBc Spurious-Free Dynamic Range
-75dB Total Harmonic Distortion
ꢀ High Output Drive: 120mA
ꢀ Low, 5.5mA Supply Current
ꢀ 400µA Shutdown Supply Current
ꢀ Space-Saving SOT23-5, µMAX, or QSOP Packages
