Product details
Overview
DG507AMWI/PR from Maxim Integrated is a monolithic CMOS differential 8-channel (2-of-16) analog multiplexer with break-before-make switching, ±4.5V to ±18V dual-supply operation, 270Ω typical on-resistance at ±15V, <1µs switching transition time, and -55°C to +125°C operating temperature range-used for precision signal routing in high-reliability data acquisition and avionics systems.
For engineers reviewing the DG507AMWI/PR datasheet, DG507AMWI/PR pinout, DG507AMWI/PR application, or DG507AMWI/PR equivalent, this page delivers verified electrical parameters, package mapping to 28-pin Wide SO, functional role in bidirectional analog path selection, and validated drop-in alternatives for legacy-compatible designs.
Technical Context
The DG507AMWI/PR implements a fully symmetrical, bidirectional analog switch matrix controlled by four TTL/CMOS-compatible address inputs (A0–A3) and an active-high enable input (EN), supporting sequential selection of one of eight differential pairs (S1a/S1b through S8a/S8b). Its latch-up proof construction ensures robustness during power sequencing.
It operates across full analog signal range from V− to V+, delivering channel-to-channel RDS(ON) matching within 6% and off-isolation of 68dB at 500kHz-enabling accurate multiplexing in high-precision instrumentation without signal crosstalk or rail-dependent distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail analog signals without clipping when powered at ±15V |
| RDS(ON) (Typical) | 270Ω at ±15V - low on-resistance enables minimal gain error in precision amplifier front-ends |
| Switching Time | 0.6µs - fast channel transition supports sampling rates up to ~1.2MHz in time-multiplexed systems |
| Off-Isolation | 68dB at 500kHz - suppresses crosstalk between inactive channels in multi-sensor data loggers |
| Supply Range | ±4.5V to ±18V - accommodates industrial ±5V, ±12V, and avionics ±15V supply rails |
| Operating Temp | -55°C to +125°C - qualified for extended-range military and aerospace environments |
| Enable Turn-On Time | 1µs - allows synchronous activation with system control logic without timing margin concerns |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Harris HI507 | Same pinout and function but rated only to +85°C (B-suffix); higher RDS(ON) (typ. 350Ω) | Limited to commercial/industrial temp range; not suitable for extended-range aerospace deployment | Select DG507AMWI/PR when full -55°C to +125°C operation and lower on-resistance are required |
| Intersil IH6216 | Drop-in replacement per datasheet; slightly higher off-leakage (±20nA vs. ±5nA at 25°C) | Acceptable for lower-precision data logging but may introduce offset in µV-level sensor interfaces | Prefer DG507AMWI/PR for high-accuracy applications where sub-nA leakage impacts measurement fidelity |
Compared with HI507 and IH6216, DG507AMWI/PR delivers extended temperature capability, lower on-resistance, and tighter leakage specs-making it the preferred choice for mission-critical analog signal routing where long-term stability and rail-to-rail fidelity are non-negotiable.

FAQ
What is the maximum analog signal voltage range supported by DG507AMWI/PR?
DG507AMWI/PR supports an analog signal range from V− to V+, which spans ±15V when operated at ±15V supplies. This allows full-rail signal handling without clipping, making DG507AMWI/PR suitable for applications such as precision instrumentation and avionics where input signals approach supply rails.
Does DG507AMWI/PR require external pull-up or pull-down resistors on address inputs?
No, DG507AMWI/PR features TTL- and CMOS-compatible digital inputs with guaranteed thresholds (VAL ≤ 0.8V for logic low, VAH ≥ 2.4V for logic high) and low input current (±0.002µA typical), eliminating the need for external biasing resistors on A0–A3 or EN pins in standard 3.3V or 5V logic systems.
Can DG507AMWI/PR be used in a demultiplexer configuration?
Yes, DG507AMWI/PR supports bidirectional signal flow and functions identically as a demultiplexer: a single differential input applied to Da/Db can be routed to any selected S1a/S1b through S8a/S8b pair. Its symmetrical RDS(ON) and capacitance ensure matched performance in both directions.
What is the thermal performance of DG507AMWI/PR in its Wide SO package?
In the 28-pin Wide SO package, DG507AMWI/PR has a thermal resistance θJA of 12.5°C/mW above +75°C, enabling 1000mW continuous power dissipation at +75°C ambient. This supports reliable operation in sealed enclosures or high-density PCB layouts without forced airflow.
Is DG507AMWI/PR pin-compatible with the DG507ACWI variant?
Yes, DG507AMWI/PR shares identical pinout, footprint, and functionality with DG507ACWI-the only difference is temperature grade: DG507AMWI/PR is rated for -55°C to +125°C (M-suffix), while DG507ACWI is rated for 0°C to +70°C (C-suffix). Both use the same W28-5 Wide SO package.
