Description
AI
The INA332 and INA2332 are rail-to-rail output, low-power CMOS instrumentation amplifiers that offer wide range, single-supply, and bipolar-supply operation. Using a special manufacturing flow, the INA332 family provides the lowest cost available, while still achieving low-noise amplification of differential signals with 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 multichannel applications.
Configured internally in a gain of 5V/V, the INA332 offers flexibility in higher gains by choosing external resistors.
The INA332 rejects line noise and its harmonics because common-mode error remains low even at higher frequencies.
High bandwidth and slew rate make the INA332 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 INA332 outperforms discrete designs.
Additionally, because they are specified for wide temperature range of –55°C to +125°C and operating range of –65°C to +150°C, the INA331 family can be used in demanding environments.
