Detailed Description
The MAX4188/MAX4189/MAX4190 are very low-power,
current-feedback amplifiers featuring bandwidths up to
250MHz, 0.1dB gain flatness to 80MHz, and low differ-
ential gain (0.03%) and phase (0.05°) errors. These
amplifiers achieve very high bandwidth-to-power ratios
while maintaining low distortion, wide signal swing, and
excellent load-driving capabilities. They are optimized
for ±5V supplies but are also fully specified for single
+5V operation. Consuming only 1.5mA per amplifier,
these devices have ±55mA output current drive capabil-
ity and achieve low distortion even while driving 150
loads.
Wide bandwidth, low power, low differential phase/gain
error, and excellent gain flatness make the MAX4188
family ideal for use in portable video equipment such
as video cameras, video switchers, and other battery-
powered equipment. Their two-stage design provides
higher gain and lower distortion than conventional sin-
gle-stage, current-feedback amplifiers. This feature,
combined with a fast settling time, makes these devices
suitable for buffering high-speed analog-to-digital con-
verters.
The MAX4188/MAX4189/MAX4190 have a high-speed,
low-power disable mode that is activated by driving the
amplifiers’ DISABLE input low. In the disable mode, the
