The LTA180Q current sensing amplifier is designed specifically for cost optimized applications. The voltage drop across the current detection resistor can be detected in a common mode voltage range of -0.3 to+30V independent of the power supply voltage. LTA180 integrates a matched resistor gain network with four fixed gain device options: 20V/V, 50V/V, 100V/V, or 200V/V. This matching gain resistor network can minimize gain errors and reduce temperature drift to the greatest extent possible.

LTA180Q has passed the AEC-Q100 vehicle grade reliability certification issued by a third-party matching organization with CNAS qualifications.

图片

LTA180Q has successfully passed a series of train level certification tests, including environmental stress acceleration verification, life acceleration simulation verification, packaging verification, chip manufacturing reliability verification, electrical verification, and failure screening verification. The production and manufacturing quality system complies with the IATF16949 standard, and the product itself is certified according to the AEC-Q100 Grade 1 standard.


AEC-Q100 certification is the entry ticket for integrated circuit manufacturers into the automotive industry. Although it is not a mandatory certification system, it has now become a universal testing standard in the automotive electronics field.

01

AEC

The Automotive Electronics Council (AEC) was established by Chrysler, Ford, and General Motors to establish a universal set of parts qualification amatchnd quality system standards. AEC is the "Automotive Electronics Council", a group formed by major automobile manufacturers and major component manufacturers in the United States, with the aim of standardizing the reliability and certification standards of in vehicle electronic components. AEC has established quality control standards.


02

Definition

AEC-Q100 is a product level quality certification standard for integrated circuits (chips).


03

Industry status

It is one of the indicators to determine whether a chip product has the qualification for automotive use, with a focus on quality and reliability.
