SBAS897C March 2018 – June 2022 AMC1311-Q1
PRODUCTION DATA
Do not leave the analog input (IN pin) of the AMC1311-Q1 unconnected (floating) when the device is powered up on the high-side. If the device input is left floating, the bias current may generate a negative input voltage that exceeds the specified input voltage range, causing the output of the device to be invalid.
Do not connect protection diodes to the input (IN pin) of the AMC1311-Q1. Diode leakage current can introduce significant measurement error especially at high temperatures. The input pin is protected against high voltages by its ESD protection circuit and the high impedance of the external restive divider.
