SBOS386A May 2019 – May 2020 INA186-Q1
The INA186-Q1 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 (typ), 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-Q1 goes to a high-impedance state when disabled. Therefore, you can connect multiple outputs of the INA186-Q1 together to a single ADC or measurement device, as shown in Figure 29.
When connected in this way, enable only one INA186-Q1 at a time, and make sure all devices have the same supply voltage.
