Maxim Integrated Rail to Rail Current Sensing Amplifier Single 8-Pin SOIC MAX9919FASA+

Maxim Integrated MAX9919FASA+ is a rail to rail current sensing amplifier in a compact single 8-pin SOIC package designed for precision measurement of current in diverse applications. Operating from a single supply voltage between 4.5V and 5.5V, this component facilitates accurate uni- or bidirectional current sensing with a maximum gain bandwidth product of 250 kHz. The device includes rail-to-rail output capability, allowing full utilization of the supply voltage range for signal output, enhancing measurement precision.

Its high common mode rejection ratio (96 dB) enables it to accurately sense currents in noisy electrical environments, making it suitable for automotive and industrial current monitoring tasks. The supply current is only 2.2 mA, which supports energy-efficient system designs. The MAX9919FASA+ meets automotive industry standards with AEC-Q100 qualification, ensuring it can operate reliably in harsh temperature environments ranging from -40°C to 125°C.

The 8-pin SOIC surface-mount package saves valuable board space in compact electronic systems. Protective clamping is reduced, allowing the device to handle high inductive kickback voltages, making it ideal for current monitoring in inductive loads such as motors and solenoids. Typical applications include H-Bridge motor current sensing, super-capacitor charge and discharge monitoring, solenoid current sensing, and high-voltage precision monitoring.

This current sensing amplifier suits industrial, automotive, laboratory, and manufacturing applications requiring high precision, reliability, and compact form factor. Its robust performance supports both AC and DC current sensing in a wide array of environments.
