Analog Devices’ Multiplexers Offer High Robustness, Low Charge Injection and Low Leakage
09 Agosto 2012 - 6:01AM
Business Wire
Analog Devices, Inc., (ADI), a global leader in high-performance
semiconductors for signal-processing applications, today introduced
two multiplexers that are able to guarantee latch-up prevention in
high-voltage industrial applications operating up to ±22 V.
Latch-up, an undesirable high-current state that persists until the
power supply is turned off, can lead to device failure.

The ultra-low (0.35 pC) 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 (20 pA) 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.
ADG5206 and ADG5207 Features
- Trench isolation between the N-channel
and P-channel transistors of each CMOS switch provides guaranteed
latch-up protection
- Operate from ±9 V to ±22 V in
applications where the analog signal is bipolar and from +9 V to
+40 V in applications where the analog signal is unipolar
- Features 3.5-pF off-source capacitance,
60-MHz -3dB bandwidth, ultra-low charge injection (0.35 pC @ 0 V)
and source off leakage (400 pA @ 125 °C) performance.
- Operate equally well in both directions
when ON and have an input signal range that extends to the power
supplies. In the OFF condition, signal levels up to the supplies
are blocked. The switches exhibit break-before-make switching
action for use in multiplexer applications.
