Ultra-Small, 1.8V, µPower,
Rail-to-Rail I/O Op Amps
General Description
The MAX4291/MAX4292/MAX4294 family of micropow-
er operational amplifiers operates from a 1.8V to 5.5V
single supply or ±0.9V to ±2.75V dual supplies and has
Rail-to-Rail® input/output capabilities. These amplifiers
provide a 500kHz gain-bandwidth product and 120dB
open-loop voltage gain while using only 100µA of sup-
ply current per amplifier. The combination of low input
offset voltage (±200µV) and high open-loop gain makes
them ideal for low-power/low-voltage, high-precision
portable applications.
The MAX4291/MAX4292/MAX4294 have an input com-
mon-mode range that extends to each supply rail, and
their outputs swing to within 46mV of the rails with a 2kΩ
load. Although the minimum operating voltage is speci-
fied at 1.8V, these devices typically operate down to
1.5V. The combination of ultra-low-voltage operation, rail-
to-rail inputs/output, and low-power consumption makes
these devices ideal for any portable/two-cell battery-pow-
ered system.
The single MAX4291 is offered in an ultra-small 5-pin
SC70 package. The dual MAX4292 is offered in a
space-saving 8-bump, 1.5mm X 1.5mm footprint, ultra
chip-scale package (UCSP™).
