General Description
The MAX4460/MAX4461/MAX4462 are instrumentation
amplifiers with precision specifications, low-power con-
sumption, and excellent gain-bandwidth product.
Proprietary design techniques allow ground-sensing
capability combined with ultra-low input current and
increased common-mode rejection performance. These
Rail-to-Rail^® output instrumentation amplifiers are offered
in fixed or adjustable gains and the option for either a
shutdown mode or a pin to set the output voltage relative
to an external reference (see Ordering Information and
Selector Guide).
The MAX4460 has an adjustable gain and uses ground
as its reference voltage. The MAX4461 is offered in fixed
gains of 1, 10, and 100, uses ground as its reference volt-
age, and has a logic-controlled shutdown input. The
MAX4462 is offered in fixed gains of 1, 10, and 100 and
has a reference input pin (REF). REF sets the output volt-
age for zero differential input to allow bipolar signals in
single-supply applications.
The MAX4460/MAX4461/MAX4462 have high-impedance
inputs optimized for small-signal differential voltages. The
MAX4461/MAX4462 are factory trimmed to gains of 1, 10,
or 100 (suffixed U, T, and H) with ±0.1% accuracy. The
typical offset of the MAX4460/MAX4461/MAX4462 is
100µV. All devices have a gain-bandwidth product of
2.5MHz.
These amplifiers operate with a single-supply voltage
from 2.85V to 5.25V and with a quiescent current of only
700µA (less than 1µA in shutdown for the MAX4461). The
MAX4462 can also be operated with dual supplies.
Smaller than most competitors, the MAX4460/
MAX4461/MAX4462 are available in space-saving 6-pin
SOT23 packages.
