The INA141 is a low power, general-purpose instrumentation amplifier offering excellent accuracy. The versatile three-op-amp design and small size make this device an excellent choice for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200 kHz at G = 100 V/V).

Simple pin connections set an accurate gain of 10 V/V or 100 V/V without external resistors. Internal input protection can withstand up to ±40 V without damage.

The INA141 is laser trimmed for very low offset voltage (50 µV), drift (0.5 µV/°C) and high common-mode rejection (117 dB at G = 100 V/V). The device operates with power supplies as low as ±2.25 V, and quiescent current is only 750 µA.

The INA141 is available in an 8‑pin SOIC package, and is specified for the −40°C to +85°C temperature range.
