Product details
Overview
MAX4522EPE+ from Maxim Integrated is a quad, low-voltage, normally open (NO) single-pole/single-throw (SPST) analog switch IC designed for rail-to-rail signal routing in precision analog and mixed-signal systems. It features 100Ω max on-resistance (at ±5V), 4Ω max channel-to-channel on-resistance matching, <1µW quiescent power consumption, and operates from ±2V to ±6V dual supplies or +2V to +12V single supply. It is used in audio signal routing, data acquisition, and battery-operated test equipment where low leakage and flat resistance over signal range are critical.
For engineers reviewing the MAX4522EPE+ datasheet, MAX4522EPE+ pinout, MAX4522EPE+ application, or MAX4522EPE+ equivalent, key selection criteria include its NO-switch configuration, -40°C to +85°C extended temperature grade, 16-pin plastic DIP package with exposed pad compatibility, ESD robustness (>2kV per Method 3015.7), and TTL/CMOS-compatible logic thresholds at +5V supply.
Technical Context
The MAX4522EPE+ implements four independent CMOS SPST switches with complementary N- and P-channel MOSFETs per channel, driven by level-translated logic inputs to ensure full rail-to-rail analog conduction. Its internal architecture includes reverse-biased ESD diodes between each analog pin and V+/V−, defining the absolute signal range and contributing to leakage current behavior.
It supports dual-supply operation (±2V to ±6V) with V+ internally connected to substrate and EP (exposed pad) tied to V+. Logic inputs accept 0.8V/2.4V thresholds for TTL/CMOS compatibility, and all analog terminals (COM/NO) are bidirectional with identical electrical characteristics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally open (NO) configuration - all four switches default open; logic high closes path between COM and NO. |
| On-Resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| On-Resistance Match (ΔRON) | 4Ω max between channels - enables matched gain/attenuation in multi-channel signal routing or multiplexing. |
| Off-Leakage Current | 10nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-critical systems. |
| Supply Range | +2V to +12V single or ±2V to ±6V dual - supports wide input voltage flexibility including +3V, +5V, and ±5V systems. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V at +5V) - eliminates need for level shifters when interfacing with standard microcontrollers or FPGAs. |
| ESD Protection | >2kV per Method 3015.7 - provides robust handling during board assembly and field operation without external protection. |
Pinout & Package
MAX4522EPE+ uses a 16-pin plastic DIP (P16-1) package with through-hole mounting and an exposed pad (EP) that must be connected to V+. Pin 1 is NC (no connection); pins 2 and 5 are V− and GND respectively; pins 11 and 13 are V+ and N.C.; COM and NO terminals are assigned per channel as shown below.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | NC (No Connection) | Not internally bonded - must remain unconnected to avoid parasitic coupling or latch-up risk. |
| 2, 15, 10, 7 | COM1–COM4 | Analog common terminals - bidirectional signal ports; connect to source or load depending on routing topology. |
| 3, 14, 11, 6 | NO1–NO4 | Normally open analog terminals - conduct only when corresponding INx = logic high; interchangeable with COMx. |
| 16, 13, 8, 5 | IN1–IN4 | Digital control inputs - active-high logic; drive internal level translators to switch COM–NO path. |
| 4 | V− | Negative analog supply - set to GND for single-supply operation; defines lower bound of analog signal range. |
| 5 | GND | Digital ground reference - separate from analog return; no direct connection to analog signal paths. |
| 11 | V+ | Positive analog/digital supply - powers logic core and switch drivers; substrate tie point; EP must connect here. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ - enables full dynamic range utilization in ±5V op-amp circuits or single-supply ADC front-ends. |
| Low on-resistance flatness (12Ω max) | Minimizes distortion across signal swing - critical for audio routing and precision instrumentation where THD must stay <0.1%. |
| Separately controlled SPST switches | Independent INx control per channel - allows flexible signal matrix configuration without shared enable logic or timing constraints. |
| Pin compatibility with DG211/DG212/DG213 | Enables drop-in replacement in legacy designs - reduces redesign effort and qualification time for industrial test equipment upgrades. |
| Charge injection ≤5pC | Reduces glitch-induced settling errors in sample-and-hold or multiplexed ADC applications - improves effective resolution by ≥12 bits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522ESE+ | Same electrical specs but in 16-pin narrow SO package (S16-2); no exposed pad; 8.7mm × 3.9mm footprint. | Better suited for space-constrained PCBs; requires rework for thermal management due to lack of EP. | Select for surface-mount production where DIP insertion is impractical and thermal load is low. |
| ADG1412BRUZ | Quad SPST, NO, 1.5Ω typical RON (vs. 100Ω max for MAX4522EPE+); higher supply current (120µA vs. <1µA); +125°C max rating. | Targeted at high-speed, low-RON applications (e.g., RF switching); not suitable for ultra-low-power or cost-sensitive battery systems. | Choose only when sub-2Ω on-resistance and faster switching (tON = 12ns) outweigh power and cost trade-offs. |

FAQ
What is the maximum analog signal range supported by the MAX4522EPE+?
The MAX4522EPE+ supports rail-to-rail analog signals from V− to V+. With ±5V dual supplies, this equals ±4.5V; with +5V single supply (V− = GND), it spans 0V to +4.5V. Exceeding these limits forward-biases internal ESD diodes, risking damage if current exceeds ±10mA continuous.
Does the MAX4522EPE+ require external pull-up or pull-down resistors on its digital inputs?
No. The MAX4522EPE+ has internally defined TTL/CMOS-compatible logic thresholds (0.8V low, 2.4V high at +5V), and input leakage is ±1µA max. External resistors are unnecessary unless noise immunity in high-EMI environments demands stronger drive - in which case 10kΩ pull-ups to V+ are sufficient.
Can the MAX4522EPE+ operate reliably with a +3V single supply?
Yes. The MAX4522EPE+ is fully specified down to +2.7V single supply. At +3V, on-resistance rises to 600Ω max (vs. 100Ω at ±5V), but logic thresholds remain valid (0.8V/2.4V), and off-leakage stays ≤10nA at +85°C - making it viable for ultra-low-power sensor nodes where speed is secondary to energy efficiency.
How is the exposed pad (EP) on the MAX4522EPE+ package used?
The exposed pad on the MAX4522EPE+ must be soldered and electrically connected to V+. It serves as both a thermal path (reducing θJA by ~30%) and a substrate tie point. Leaving it floating or grounding it violates the internal bias scheme and may cause latch-up or parametric shift in on-resistance and leakage.
Is the MAX4522EPE+ pin-compatible with the industry-standard DG212?
Yes. The MAX4522EPE+ is explicitly designed as a pin-compatible upgrade to the DG212 in 16-pin DIP packaging. Pin assignments for COM/NO/IN/V+/V−/GND match exactly, enabling direct replacement without PCB modification - provided the DG212's higher on-resistance (150Ω) and lower ESD rating (1.5kV) are acceptable in the target application.
