1 Overview

The INA190-EP devices are voltage output, high- and low-side measurement, bidirectional, zero-drift current shunt monitors. This family of devices has gains that range from 25 V/V to 500 V/V. The voltage developed across the device inputs is amplified by the corresponding gain of the specific device and is presented at the output pin. These devices can accurately sense voltage drops across shunts at common-mode voltages from –0.2 V to 40 V, independent of supply voltages. These devices operate with supply voltages between 1.7 V and 5.5 V and draw a maximum of 65 µA at room temperature. The low offset of the zero-drift architecture enables the sensing of very small differential input voltage which helps widen the usable input dynamic range. Additionally, the INA190-EP has a very low input bias current and thus, can easily measure microamps of current. Finally, the INA190-EP is an enhanced version, and is capable of an extended temperature range of -55°C through 150°C.

The INA190-EP devices are currently available in a DDF package. Table 1-1 summarizes the available device gain options.
