What are the key features of ADG1634?
- 4.5 Ω maximum on-resistance enabling low insertion loss in precision analog signal routing and multiplexing circuits
- Multi-supply compatibility with ±5 V, +12 V, +5 V, and +3.3 V operation for broad system integration flexibility
- Triple/quad SPDT configuration in a 16-pin TSSOP providing multiple independent switch channels in minimum PCB area
What is ADG1634 used for?
The ADG1634 is ideal for precision instrumentation, data acquisition multiplexers, and automatic test equipment (ATE) where low on-resistance and minimal charge injection are needed to preserve signal integrity. Its multi-supply compatibility makes it suitable for mixed 3.3 V digital and ±5 V analog systems found in medical diagnostic equipment and industrial sensor interfaces. Audio routing matrices, communication signal switching, and relay replacement circuits in portable instruments also benefit from its low 4.5 Ω RON and compact 16-pin TSSOP footprint.

Frequently Asked Questions
What is the on-resistance specification of the ADG1634 and how does it affect signal accuracy?
The ADG1634 guarantees a maximum on-resistance of 4.5 Ω across its operating voltage range, which introduces a predictable series resistance in switched signal paths. In precision measurement systems, this 4.5 Ω series resistance combined with load impedances above 10 kΩ creates less than 0.045% signal attenuation, making it suitable for 12-bit to 16-bit accuracy data acquisition multiplexers.
Which supply configurations does the ADG1634 support for mixed-voltage system integration?
The ADG1634 operates from ±5 V dual supply, single +12 V, single +5 V, or single +3.3 V supplies, covering virtually all common analog and mixed-signal system power rails. This flexibility allows a single part to be used across 3.3 V digital systems and ±5 V analog front-ends without redesigning the switch stage, reducing component variants in a product family.
How many independent switch channels does the ADG1634 provide and what is the package size?
The ADG1634 integrates 4 independent SPDT switches in the quad configuration within a 16-pin TSSOP package measuring approximately 5 mm × 4.4 mm. Each SPDT channel has its own control input, allowing simultaneous independent switching of 4 separate signal paths at speeds suitable for audio, baseband, and low-frequency RF signal routing up to several megahertz.
In what precision measurement applications can ADG1634 replace mechanical relays?
The ADG1634 replaces mechanical relays in applications where switching speed below 100 ns, PCB space savings of over 80%, and a lifespan exceeding 10 billion switching cycles are required. Automated test equipment channel selectors, medical impedance analyzers, and laboratory signal routers benefit from its 4.5 Ω on-resistance and negligible contact bounce compared to relays with bounce times of several milliseconds.
