NORWOOD, Mass. -- (Business Wire)
Analog
Devices, Inc. today introduced a quad-channel protector and two
multiplexers offering +/-55-V overvoltage protection (OVP) for precision
converters, amplifiers and other components that operate from a low
voltage of 4.5 V up to 36 V. The ADG5462F
quad channel protector, ADG5248F
8:1 multiplexer and ADG5249F
differential 4:1 multiplexer offer +/-55-V OVP in power-on and power-off
stages and provide robust, precision protection against hot-swapping and
operator miss-use events, thereby protecting downstream analog
components. By providing on-chip fault diagnostics, the new devices are
the first in the industry to detect and avoid defective channels, which
simplifies fault detection algorithms and improves system uptime. The
new products maximize design flexibility by enabling users to define
fault-trigger levels independent of primary supplies. By also removing
the need for multiple discrete protection components, the ADG5462F,
ADG5248F and ADG5249F optimize PCB area and simplify the design process.
The devices are optimized for precision instrumentation, process control
and avionics applications.

The ADG5248F8:1 multiplexer and ADG5249F
differential 4:1 multiplexer maximize throughput for small signal
measurement such as thermocouples or resistance temperature detectors
(RTDs) by offering best-in-class, low-fault leakage of 70 nA, which is
10 times lower than competing solutions, and on-leakage of 20 nA. These
levels ensure that the user can take accurate measurements when other
multiplexer I/O channels are in an over-voltage fault condition.
Key Features:
Over-voltage detection on source pins
-
Minimum secondary supply level: 4.5-V single-supply
-
Over-voltage protection up to +/−55 V
-
4-kV HBM (human body model) ESD (ADG5462F)
VSS to VDD analog signal range
-
+/-5-V to +/-22-V dual-supply operation
-
8-V to 44-V single-supply operation
-
Fully specified at +/-15 V, +/-20 V, +12 V, and +36 V
Operating Temperature Range −40°C to +125°
ADG5462F: Ultra-low on-resistance of 10 ohm and on-resistance
flatness of 0.5 ohm minimizes system total harmonic distortion and
enhances noise performance.
ADG5248F/49F: Ultra-low charge injection of 0.8 pC and
on-capacitance of 19 pF enables higher accuracy, faster channel
switching in multiplexed systems.
