Precision is a summation of various DC and AC parameters (e.g. low noise, low offset voltage, low input bias current and other application dependent parameters) and National optimizes these requirements for a wide variety of precision applications. The tables below highlight some of National’s industry-leading precision amplifier products by end application. Many National Op Amps are tested at three temperatures to ensure consistent performance to specification.
Automotive applications, such as crash detection, active noise cancellation, and navigation, require low offset voltage, low input bias current, and low offset voltage drift at a high voltage supply range. National offers an increasing number of AEC-Q100-compliant devices. National also has the only current sense operational amplifiers which have tested performance over temperature. National provides the latest solutions making automobiles more efficient, safer, and greener.
