Hi,
I am doing a current measurment for control that is being fed into a DSP, I would like to use the INA129/128 for this measurment but I only have one 5V power supply availbale. I know that the INA128/129 are not adevertised as single power supply inst. amp, but can they still be used with s asingle power supply assuming that 5V is enough dynamic range ?
regards

Ina 129 . It operates with power supplies as low as ±2.25V.
INPUT Common-Mode Voltage Range (min) (V+) – 2 ....(V–) + 2 {2..3 V in yours application}
OUTPUT Voltage:(V-)+ 1.4.....(V+) – 1.4 {1.4..3.6V in your application}
