Descripción de INA331
The INA331 and INA2331 are rail-to-rail output, low-power CMOS instrumentation amplifiers that offer wide range, single-supply operation as well as bipolar-supply operation. The INA331 family provides low-cost, low-noise amplification of differential signals with a low quiescent current of 415µA (dropping to 0.01µA when shutdown). Returning to normal operation within microseconds, this INA can be used for battery or multi-channel applications.
Configured internally in a gain of 5V/V, the INA331 offers flexibility in higher gains by choosing external resistors.
The INA331 rejects line noise and its harmonics, because common-mode error remains low even at higher frequencies.
High bandwidth and slew rate makes the INA331 ideal for directly driving sampling Analog-to-Digital (A/D) converters as well as general-purpose applications.
With high precision, low cost, and small packages, the INA331 outperforms discrete designs. They are specified for a wide temperature range of -55°C to +125°C.
