ADG5423BRMZ

The ADG5421/ADG5423 switches are used in instrumentation, industrial, aerospace, and other harsh environments prone to latch-up. They are suitable for single-supply operation from 9V to 40V and dual-supply operation from ±9V to ±22V. These switches have an 8kV human body model ESD rating, eliminating the need for separate protection circuitry designs in some applications. [1] Additionally, the ADG5421/ADG5423 switches are ideal for data acquisition and gain switching applications where low distortion is critical. Their ultralow on resistance and on-resistance flatness make them suitable for such applications. The switches' latch-up immune construction and high ESD rating also make them more robust in harsh environments. [1]

The human body model (HBM) ESD rating for the ADG5421/ADG5423 switches is 8 kV. [16]

The on resistance of the ADG5421/ADG5423 switches is as follows: - For a single supply of 36V, the typical on resistance is 14.5Ω, with a maximum of 24Ω [6]. - For a dual supply of ±20V, the typical on resistance is 12.5Ω, with a maximum of 22Ω [4]. - For a dual supply of ±15V, the typical on resistance is 13.5Ω, with a maximum of 23Ω [2]. Therefore, the on resistance values for the ADG5421/ADG5423 switches vary depending on the supply voltage configuration. [2, 4, 6].
