Description

DATASHEET instrumentation amplifier INA826 and a difference amplifier INA159 . The output of the INA159 connects to the AIN0 input of the ADS1248 and the mid-supply These features allow the INA159 to be employed as a dual-polarity, bidirectional current monitor. An additional instrumentation or operational amplifier needs to The input to channel B1 is a bipolar configuration using the INA159 to input to the ADS7864MEVM board for channel B1 is comprised the INA159 difference. isolation transformer is directly connected to the input of a differential amplifier ( such as TIs INA159 ). The high-input impedance of the 100k resistor and the The INA159 provides the attenuation that allows this circuit to easily interface with 3.3-V or 5-V analog-to-digital converters (ADCs).
