MAXIM INTEGRATED / ANALOG DEVICES MAX9919NASA Current Sense Amplifier
The MAX9919NASA+ is a high-precision current sense amplifier housed in an 8-pin NSOIC package. It supports single-supply operation from 4.5V to 5.5V and is designed for both unidirectional and bidirectional current measurement, with a fixed gain of 90 V/V. The amplifier features a high input common-mode voltage range from -20V to +75V, making it suitable for monitoring inductive loads such as motors and solenoids, where negative voltages can occur due to inductive kickback, reverse battery conditions, or transients. It operates effectively across automotive temperature ranges from -40°C to 125°C, with a bandwidth of 120kHz (at a 50mV sense voltage) and a slew rate of 3V/μs. The device offers excellent accuracy with a gain error of ±0.16% and an input offset voltage of ±0.18mV at room temperature. It features rail-to-rail output and reference input for bidirectional operation, high CMRR of 96dB, and PSRR of 103dB, supporting a wide range of precision AC and DC current sensing applications such as high-precision monitoring, supercapacitor charge/discharge, and high-voltage current measurement. Additional specifications include input offset current of ±8μA and input bias current of ±175μA at 25°C. Market demand has extended lead times, and delivery may fluctuate. Sales are exempt from discounts.
