SBOS318B April 2019 – July 2021 INA186
The INA186 features an active-high ENABLE pin that shuts down the device when pulled to ground. When the device is shut down, the quiescent current is reduced to 10 nA (typical), and the output goes to a high-impedance state. In a battery-powered application, the low quiescent current extends the battery lifetime when the current measurement is not needed. When the ENABLE pin is driven to the supply voltage, the device turns back on. The typical output settling time when enabled is 130 µs.
The output of the INA186 goes to a high-impedance state when disabled. Figure 7-5 shows how to connect multiple outputs of the INA186 together to a single ADC or measurement device.
When connected in this way, enable only one INA186 at a time, and make sure all devices have the same supply voltage.
