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 rail-to-rail analog paths. It features 100Ω max on-resistance (at ±5V), 4Ω max channel-to-channel on-resistance matching, and 12Ω max on-resistance flatness over the full signal range. Each switch supports dual supplies (±2V to ±6V) or single +2.7V to +12V operation and handles analog signals from V− to V+, making it suitable for battery-powered data acquisition front-ends.
For engineers reviewing the MAX4522CEE datasheet, MAX4522CEE pinout, MAX4522CEE application, or MAX4522CEE equivalent, key selection criteria include its TTL/CMOS-compatible logic thresholds (+0.8V/2.4V), <1µW quiescent power, 1nA off-leakage at +25°C, and pin compatibility with DG211/DG212/DG213 in QSOP-16 packaging.
Technical Context
The MAX4522CEE implements four independent CMOS transmission gates-each consisting of paralleled N- and P-channel MOSFETs driven by phase-inverted control signals derived from logic-level translators. Its analog path operates without ground reference, bounded only by V+ and V−, enabling true rail-to-rail signal handling across ±5V, +5V, or +3V supply configurations.
ESD protection (>2kV per Method 3015.7) is achieved via internal diodes between each analog pin and both V+ and V−. Leakage current originates almost entirely from reverse-biased ESD diodes, with off-leakage specified at 1nA (+25°C) and 10nA (+85°C), while charge injection is limited to 1–5pC (CL = 1nF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-resistance match (ΔRON) | 4Ω max - enables matched gain/attenuation across channels in multi-path signal conditioning |
| On-resistance flatness (RFLAT) | 12Ω max - maintains consistent insertion loss across full analog input range (±4.5V) |
| Off-leakage current | 1nA at +25°C - preserves high-impedance node integrity in sensor interfaces and sample-hold circuits |
| Logic thresholds | +0.8V low / +2.4V high - guarantees reliable TTL/CMOS compatibility with +5V digital control |
| Supply range | +2.7V to +12V single or ±2V to ±6V dual - supports wide battery and industrial supply flexibility |
| Turn-on/off time | 60ns/20ns typical at +4.5V - enables fast switching in multiplexed ADC/DAC systems |
Pinout & Package
MAX4522CEE is housed in a 16-pin QSOP package (E16-4), 3.9mm × 4.9mm body, 0.635mm pitch, with gull-wing leads and no exposed pad. Pin 1 is NC (not connected); pins 2 and 5 are V− and GND respectively; pins 11 and 13 are V+ and COM2; all INx/COMx/NOx pins follow standard analog switch terminal mapping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 15,14,7,6) | Digital control inputs | Accept TTL/CMOS logic; high = NO switch closed, low = open |
| COM1–COM4 (Pins 16,13,8,5) | Analog common terminals | Signal bidirectional ports - connect to system signal path or load |
| NO1–NO4 (Pins 1,12,10,9) | Normally open analog terminals | Connect to source when switch is enabled; floating when disabled |
| V+ (Pin 11) | Positive supply | Powers analog switches and internal logic; substrate tie point |
| V− (Pin 2) | Negative supply | Sets lower analog rail; connect to GND for single-supply operation |
| GND (Pin 3) | Digital ground reference | Reference for logic inputs only; no analog signal reference |
| N.C. (Pin 4) | No connection | Internally unconnected; leave unpopulated or float |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output voltages from V− to V+ - eliminates level-shifting in mixed-supply systems |
| Low power consumption | <1µW typical - extends battery life in portable instrumentation and IoT edge nodes |
| High ESD robustness | >2kV per Method 3015.7 - reduces field failure risk in handling and assembly |
| Pin compatibility | Drop-in replacement for DG211/DG212/DG213 - minimizes PCB redesign in legacy upgrades |
| Wide supply flexibility | Operates from +2.7V single or ±2V dual - accommodates Li-ion, alkaline, and industrial rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1421BRUZ | Lower 1.5Ω RON but requires ≥±4.5V dual supply; no +2.7V single-supply support | Better for high-precision instrumentation where supply headroom allows; unsuitable for 3V battery systems | Select MAX4522CEE for 2.7V–12V supply flexibility and guaranteed 1nA leakage at +25°C |
| TS5A23157DCUR | 3.3V-only operation; 0.9Ω RON but 100nA off-leakage at +85°C vs. 10nA for MAX4522CEE | Optimized for mobile SoC I/O expansion; lacks bipolar supply capability and ESD rating | Choose MAX4522CEE when dual-supply operation, -40°C to +85°C extended temp, or >2kV ESD is required |

FAQ
What is the maximum allowable supply voltage difference (V+ to V−) for MAX4522CEE?
The absolute maximum V+ to V− differential voltage for MAX4522CEE is 13.0V. Exceeding this-such as with ±6V supplies having ±10% tolerance (13.2V peak)-can cause permanent damage. Designers must ensure worst-case supply tolerances and transient spikes remain within this limit. MAX4522CEE operates reliably across ±2V to ±6V, but derating is recommended for long-term reliability.
Does MAX4522CEE support single-supply operation below +3V?
Yes, MAX4522CEE is fully specified for single +2.7V operation. At +2.7V, typical on-resistance is 600Ω (VCOM = 1.0V, ICOM = 0.1mA), and logic thresholds remain at +0.8V/+2.4V. This enables use in Li-ion–powered devices with brown-out conditions, though designers should verify RON impact on signal fidelity at lowest operating voltage.
How does the pin configuration of MAX4522CEE differ from MAX4521CEE?
MAX4522CEE uses NO (normally open) switches, so pins 1,12,10,9 are NO1–NO4; MAX4521CEE uses NC (normally closed) switches, assigning those same pins as NC1–NC4. Both share identical COMx, INx, V+, V−, GND, and N.C. pinouts in QSOP-16. This functional difference means MAX4522CEE defaults to open-circuit state, critical for fail-safe signal isolation.
Can MAX4522CEE be used in AC-coupled audio paths without DC bias concerns?
Yes. Because MAX4522CEE's analog path has no internal DC reference-signals pass bidirectionally between COM and NO terminals independent of GND-AC-coupled audio paths require no external bias networks. The device's rail-to-rail capability supports ±2.5V audio swings directly, and 2pF off-capacitance minimizes crosstalk in multi-channel routing.
Is the exposed pad present in the MAX4522CEE QSOP package?
No. The MAX4522CEE uses the standard QSOP-16 package (E16-4) without an exposed pad. Exposed-pad variants (e.g., MAX4522CGE) use QFN-EP packaging. For MAX4522CEE, thermal dissipation relies on lead-frame conduction through pins 2 (V−), 3 (GND), and 11 (V+); no EP connection is required or supported.
