Instrumentation Amplifiers
The MAX4460/MAX4461/MAX4462 are instrumentation
amplifiers with precision specifications, low-power consumption, 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 the 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 voltage, 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 voltage 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 …
