DESCRIPTION

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 manu-

facturing flow, the INA332 family provides the lowest cost

available, while still achieving low-noise amplification of dif-

ferential signals with low quiescent current of 415µA (drop-

ping to 0.01µA when shut down). Returning to normal opera-

tion within microseconds, this INA can be used for battery or

multichannel applications.

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 a wide tempera-

ture range of –55°C to +125°C, the INA332 family can be

used in demanding environments.

Configured internally in a gain of 5V/V, the INA332 offers

flexibility in higher gains by choosing external resistors.
