Analog Devices’ Multiplexers Offer High Robustness,
Low Charge Injection and Low Leakage
August 9, 2012 Press Release
-- ADI’s ADG5206/5207 16-channel and differential
8:1 multiplexers offer guaranteed latch-up protection for
industrial, instrumentation and process control applications
NORWOOD, Mass.--(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
Pricing and Availability
- 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.
Samples and evaluation board are currently available.
