Product details
Overview
MAX4530CPP+ from Maxim Integrated is an 8-channel CMOS analog multiplexer with dual enable inputs, address latching, and rail-to-rail signal handling. It operates from a single +2V to +12V supply or dual ±2V to ±6V supplies, features 150Ω max on-resistance (8Ω max matching), 1nA off-leakage at +25°C, and 150ns turn-on time at ±4.5V - enabling precise signal routing in battery-powered data acquisition systems.
For engineers reviewing the MAX4530CPP+ datasheet, MAX4530CPP+ pinout, MAX4530CPP+ application, or MAX4530CPP+ equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases in avionics and ATE equipment, and two validated alternative parts with documented technical and application differences.
Technical Context
The MAX4530CPP+ implements a latch-controlled 3-bit address decoder driving eight transmission-gate switch paths between a common terminal (COM) and normally open terminals (NO0–NO7). Its dual enable logic (EN1/EN2) supports break-before-make switching with 4ns typical interval, and internal level translators ensure TTL/CMOS compatibility across supply voltages.
All analog paths are bidirectional and support rail-to-rail operation up to ±6V or +12V. The device uses matched P/N MOSFET pairs per channel to achieve ≤8Ω on-resistance matching and <1.5pC charge injection - critical for low-distortion sampling in precision instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel single-pole analog multiplexer with address latching and dual enable control |
| Supply Range | +2V to +12V single supply or ±2V to ±6V dual supply - enables direct interface with Li-ion, ±5V, and industrial 12V rails |
| On-Resistance | 150Ω max at +5V supply - ensures minimal gain error and THD degradation in audio and sensor signal chains |
| On-Resistance Matching | 8Ω max between channels - preserves channel-to-channel amplitude consistency in multi-sensor acquisition |
| Off-Leakage Current | 1nA at TA = +25°C - maintains high-impedance integrity for microamp-level sensor front-ends |
| Switching Speed | tON = 150ns, tOFF = 120ns at ±4.5V - supports >1MHz multiplexed sampling without settling-time penalty |
| Rail-to-Rail Operation | Full analog signal swing from V− to V+ - eliminates level-shifting circuitry for bipolar or wide-dynamic-range signals |
Pinout & Package
MAX4530CPP+ is housed in a 20-pin plastic DIP package (0.300" width) with through-hole mounting and industry-standard pin spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply input | Drives internal switch gates and logic; sets upper analog signal limit (up to +12V) |
| V− | Negative analog supply input | Connect to GND for single-supply operation; sets lower analog signal limit (down to −6V) |
| GND | Digital ground reference | Reference for logic inputs only; isolated from analog signal path and supplies |
| COM | Common analog terminal | Bidirectional node shared across all 8 channels; accepts rail-to-rail input/output signals |
| NO0–NO7 | Normally open analog terminals | Eight independent switch outputs; interchangeable as inputs or outputs; no polarity restriction |
| EN1 / EN2 | Complementary enable logic inputs | Active-high control pair enabling break-before-make sequencing; both must be high to activate switches |
| ADDA / ADDB / ADDC | 3-bit binary address inputs | Selects one of eight NOx paths to connect to COM; latched on rising edge of LE |
| LE | Address latch enable | Edge-triggered input capturing ADDA/ADDB/ADDC state; independent of EN1/EN2 timing |
| N.C. | Not connected | Pins 3 and 14 are unconnected die pads - must remain floating, not tied to any potential |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4530CWP+ | Same silicon, 20-pin SO package - 7.5mm × 12.8mm footprint vs. DIP's 6.35mm × 25.4mm | Suitable for space-constrained PCBs; requires reflow soldering instead of through-hole assembly | Select when board area is limited and surface-mount manufacturing is available. |
| ADG708BRUZ | 8-channel CMOS mux with 3.5Ω typical on-resistance, but no address latching or dual enable; 16-pin TSSOP | Lacks LE/EN1/EN2 control architecture - requires continuous address bus drive and external sequencing logic | Choose for lowest on-resistance where latch-free operation and smaller package are priorities. |
Compared with MAX4530CWP+, the MAX4530CPP+ offers identical electrical performance in a through-hole package ideal for prototyping and ruggedized systems; compared with ADG708BRUZ, it provides integrated address latching and dual-enable sequencing - reducing MCU GPIO count and eliminating external timing logic in embedded data loggers.

FAQ
What supply voltage ranges does the MAX4530CPP+ support?
The MAX4530CPP+ operates from a single +2V to +12V supply (with V− tied to GND) or dual ±2V to ±6V supplies. At ±4.5V, it achieves 150ns turn-on time and 150Ω max on-resistance. The absolute maximum rating is V+ ≤ +13V relative to V−, making it compatible with standard ±5V, +5V, and +12V industrial rails. MAX4530CPP+ maintains rail-to-rail analog signal handling across all supported supplies.
Does the MAX4530CPP+ require external pull-up or pull-down resistors on its digital inputs?
No, the MAX4530CPP+ has internally biased TTL/CMOS-compatible logic thresholds (0.8V low, 2.4V high at +5V supply) and does not require external biasing. Input currents are ±1.0µA max at VADD_H/VEN_H, so direct connection to FPGA or MCU GPIO is safe. MAX4530CPP+ logic inputs tolerate voltages up to V+ without damage due to internal ESD diodes.
How does the address latching feature of the MAX4530CPP+ simplify microcontroller interface design?
The MAX4530CPP+ uses a dedicated LE (latch enable) pin that captures ADDA/ADDB/ADDC states on its rising edge - decoupling address updates from enable timing. This allows the microcontroller to set new addresses asynchronously, then trigger switching with EN1/EN2. MAX4530CPP+ eliminates need for precise address/enable synchronization, reducing firmware overhead in real-time data acquisition systems.
Can the MAX4530CPP+ handle bipolar analog signals in single-supply mode?
Yes - when V− is tied to GND in single-supply mode, the MAX4530CPP+ still supports rail-to-rail analog signals from 0V to V+. For true bipolar signals (e.g., ±2.5V), a dual supply (±2.5V) must be used. MAX4530CPP+'s internal architecture ensures no DC bias shift or clipping occurs across its full specified analog range under either configuration.
What is the maximum signal frequency supported by the MAX4530CPP+ with acceptable isolation?
At 10MHz in a 50Ω system, the MAX4530CPP+ provides −65dB off-isolation and −1.5dB on-loss. Isolation degrades ~20dB per decade above 10MHz, limiting practical high-frequency use to ≤20MHz for critical crosstalk-sensitive applications. MAX4530CPP+'s 50MHz flat response (per Typical Operating Characteristics) applies to insertion loss, not isolation - design for <10MHz if >60dB channel separation is required.
