Frequently Asked Questions
What is the common-mode rejection ratio of the INA148UAG4?
The INA148UAG4 provides a minimum common-mode rejection ratio (CMR) of 80dB, which ensures that common-mode noise and interference are effectively suppressed, delivering accurate differential measurements even in electrically noisy industrial and automotive environments.
What supply voltage range does the INA148UAG4 support?
The INA148UAG4 operates over a wide supply voltage range of ±2.25V to ±18V, making it suitable for both low-voltage battery-powered designs and higher-voltage industrial systems. This flexibility allows designers to use a single part across multiple platform configurations.
Does the INA148UAG4 require external resistors for operation?
No, the INA148UAG4 is a unity-gain difference amplifier with all precision resistors integrated on-chip. This eliminates the need for external matching resistors, reducing component count, PCB space, and the risk of resistor mismatch errors that degrade common-mode rejection performance.
What are typical applications for the INA148UAG4?
Typical applications include industrial motor control current sensing, automotive battery management systems, bridge amplifier signal conditioning, data acquisition front-ends, and power supply monitoring. Its 80dB CMR and wide supply range make it well-suited for any application demanding precise differential voltage measurement.
What package does the INA148UAG4 come in?
The INA148UAG4 is available in an 8-pin SOIC (SO-8) package. The 'UAG4' suffix denotes the small-outline package variant with AEC-Q100 automotive qualification, offering a compact, surface-mount footprint suitable for high-density PCB designs.
