Analog – Robust low charge injection multiplexers assure latch-up protection (ADG5206)Aug 10 2012 - Semiconductors [More Semiconductors Articles]
Analog Devices has introduced two new multiplexers that are able to ‘guarantee’ latch-up prevention in high-voltage industrial applications operating up to ±22V. Latch-up, an undesirable high-current state that persists until the power supply is turned off, can lead to device failure.
The ultra-low (0.35pC) charge injection of the new multiplexers makes them suitable for data acquisition and sample-and-hold applications, where low glitch and fast settling time are required. The low leakage (20pA) feature ensures high accuracy and resolution, which is an advantage in audio and video signal routing. The ADG5206 and ADG5207 multiplexers are the latest additions to ADI’s switch and multiplexer protection products portfolio, which also includes the ADG5212 and ADG5213 – the industry lowest charge injection and low leakage latch-up proof quad switches, says the company.
