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 Ordering Information and Selector Guide in the full data sheet).

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 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 and TDFN packages.
