Product details
Overview
MAX4522CEE+ from Maxim Integrated is a quad, low-voltage, normally open (NO) SPST analog switch IC designed for precision signal routing in battery-powered and mixed-signal systems. It features 100Ω max on-resistance (at ±5V), 4Ω max channel-to-channel on-resistance matching, rail-to-rail analog signal handling, <1µW quiescent power, and TTL/CMOS-compatible logic inputs - enabling use in audio routing, data acquisition, and test equipment.
For engineers reviewing the MAX4522CEE+ datasheet, MAX4522CEE+ pinout, MAX4522CEE+ application, or MAX4522CEE+ equivalent, key selection considerations include its QSOP-16 package, +2V to +12V single-supply or ±2V to ±6V dual-supply operation, 1nA off-leakage at +25°C, 15ns typical turn-off time, and pin compatibility with DG212.
Technical Context
The MAX4522CEE+ implements four independent CMOS SPST switches with complementary N- and P-channel MOSFETs per channel, driven by logic-level translators that convert TTL/CMOS inputs into full-rail gate drive signals referenced to V+ and V−. Its architecture ensures flat on-resistance (12Ω max variation) across the full analog signal range and matched conduction paths critical for multiplexer accuracy.
Each switch operates bidirectionally with no ground reference required for analog signals; leakage current flows exclusively to V+ or V− via ESD diodes, not through adjacent channels. The device supports break-before-make timing only in the MAX4523 variant - not applicable to MAX4522CEE+ - and exhibits >2kV HBM ESD protection per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and voltage drop in low-level analog paths. |
| On-resistance match (ΔRON) | 4Ω max between channels - enables precise gain/offset matching in multi-channel signal conditioning. |
| Rail-to-rail analog range | V− to V+ - supports full dynamic range of sensors, DACs, and ADCs without level-shifting circuitry. |
| Off-leakage current | 1nA at +25°C - preserves signal integrity in high-impedance sensor interfaces and sample-hold circuits. |
| Supply range | +2V to +12V single or ±2V to ±6V dual - accommodates Li-ion, USB, and industrial supply rails without external regulators. |
| Logic thresholds | +0.8V low / +2.4V high - guarantees reliable switching with standard 5V TTL and CMOS logic drivers. |
| Turn-off time (tOFF) | 15ns typical at ±4.5V - supports fast-switching applications such as digital potentiometer emulation and chopper stabilization. |
Pinout & Package
MAX4522CEE+ is housed in a 16-pin QSOP (E16-4) package, 3.9mm × 4.9mm body, 0.635mm pitch, with exposed pad connected to V+. Pin 1 is IN1; pins 2–4 are V−, GND, NO4; pins 5–8 are COM4, IN4, IN3, COM3; pins 9–12 are NC3, N.C., V+, NO2; pins 13–16 are COM2, IN2, IN1, COM1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (pins 1,14,7,11) | Digital control input | Active-high logic drives corresponding switch; compatible with 5V TTL/CMOS levels. |
| COM1–COM4 (pins 16,13,8,5) | Analog common terminal | Bidirectional signal path node; connects to load or source depending on system topology. |
| NO1–NO4 (pins 15,12,4,2) | Normally open analog terminal | Open-circuit when INx = 0; closed to COMx when INx = 1 - defines SPST NO behavior. |
| V+ (pin 9) | Positive supply | Powers internal logic and P-channel gates; substrate tied internally; EP must be connected to V+. |
| V− (pin 2) | Negative supply | Powers N-channel gates; connect to GND for single-supply operation; sets lower analog rail limit. |
| GND (pin 3) | Digital ground reference | Reference for logic inputs only; no connection to analog signal paths - avoids ground-loop coupling. |
| N.C. (pin 10) | No connection | Internally unconnected; must remain floating or grounded per layout best practices. |
| NC2, NC3 (pins 12, 9 in MAX4521 only) | Not applicable | Not bonded or functional in MAX4522CEE+ - unused pins in this variant. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Enables direct interface with ±5V op-amps, 0–10V industrial sensors, and unipolar/bipolar DAC outputs without clamping or attenuation. |
| 100Ω max on-resistance with 4Ω matching | Reduces gain error and channel crosstalk in 4-channel multiplexers used for precision data acquisition systems. |
| 1nA off-leakage at +25°C | Preserves charge in high-Z sample-and-hold circuits and maintains accuracy in microamp-level biomedical sensor front-ends. |
| TTL/CMOS-compatible logic thresholds | Eliminates need for level shifters when interfacing with FPGA I/O banks, microcontroller GPIOs, or ASIC control logic. |
| QSOP-16 package with exposed pad | Provides thermal performance comparable to SOIC while reducing PCB footprint by ~40% - ideal for space-constrained portable instruments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522CSE+ | Same electrical specs, but in 16-pin narrow SOIC (S16-2) package - 1.5mm taller, 4mm wider than QSOP. | Preferred where thermal mass or hand-solderability outweighs board space constraints. | Select MAX4522CSE+ for prototyping or legacy SOIC footprints; MAX4522CEE+ for compact, high-density layouts. |
| ADG1412BRUZ | Quad SPST, 1.8Ω typical RON, ±15V supply capable, but higher 120µA supply current and no 2V min operation. | Suitable for high-precision, wide-supply industrial systems - not optimized for ultra-low-power or sub-3V battery operation. | Choose ADG1412BRUZ when sub-ohm RON and extended voltage range are critical; MAX4522CEE+ when power, cost, and 2V operation dominate. |
Compared with MAX4522CSE+, MAX4522CEE+ saves 35% board area and improves thermal dissipation via exposed pad; versus ADG1412BRUZ, it delivers 120× lower quiescent power and 3× lower minimum supply voltage - essential for portable and energy-harvested designs.

FAQ
What is the maximum supply voltage rating for MAX4522CEE+?
The absolute maximum V+ to V− differential voltage for MAX4522CEE+ is 13.0V. When using dual supplies, ensure their sum does not exceed this limit - e.g., ±6V supplies (12V total) are acceptable, but ±6.6V would violate the rating. For single-supply operation, V+ may range from +2V to +12V with V− tied to GND.
Does MAX4522CEE+ support rail-to-rail analog signals with a +3.3V single supply?
Yes, MAX4522CEE+ supports rail-to-rail analog signals from 0V to +3.3V when operated with V+ = +3.3V and V− = GND. At this supply, typical on-resistance is 260Ω (max 500Ω), and analog signal range remains 0V to +3.3V - verified per Electrical Characteristics table for +3V supply conditions.
Is the exposed pad on MAX4522CEE+ electrically connected, and how should it be handled?
Yes, the exposed pad (EP) on MAX4522CEE+ is internally connected to V+ and must be soldered to a V+ copper pour on the PCB. This connection provides critical thermal dissipation and reduces junction temperature rise during sustained switching - failure to connect EP may cause thermal shutdown or parametric drift under load.
Can MAX4522CEE+ be used in a break-before-make configuration?
No, MAX4522CEE+ implements four independent normally open SPST switches with no internal break-before-make timing control. That feature is exclusive to the MAX4523 variant. To achieve break-before-make behavior with MAX4522CEE+, external logic sequencing or delay circuitry must be added to the INx control lines.
What is the guaranteed off-leakage current specification for MAX4522CEE+ at +85°C?
MAX4522CEE+ guarantees 10nA maximum off-leakage current (INO_(OFF) and ICOM_(OFF)) at +85°C, as specified in the Dual Supplies Electrical Characteristics table. This value is 100% tested at maximum rated temperature and correlated to +25°C performance - critical for maintaining accuracy in high-temperature industrial sensing applications.
