Precision, Low Power, G = 10, 100 Instrumentation Amplifier

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.
