Product details
Overview
MAX4522ESE+ from Maxim Integrated is a quad, low-voltage, normally open (NO) 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, and <1µW quiescent power consumption. Each switch supports dual supplies (±2V to ±6V) or single +2.7V–+12V operation, with TTL/CMOS-compatible logic inputs - ideal for battery-powered data acquisition front-ends.
For engineers reviewing the MAX4522ESE+ datasheet, MAX4522ESE+ pinout, MAX4522ESE+ application, or MAX4522ESE+ equivalent, key selection criteria include on-resistance flatness (≤12Ω over signal range), off-leakage current (≤10nA at +85°C), ESD robustness (>2kV per Method 3015.7), and compatibility with industry-standard DG211/DG212 footprints in 16-pin SO package.
Technical Context
The MAX4522ESE+ implements four independent CMOS transmission gates, each consisting of paralleled N- and P-channel MOSFETs driven by phase-inverted signals derived from V+ and V−. Its logic-level translators ensure TTL/CMOS compatibility across supply ranges, while internal ESD diodes clamp analog pins to V+ and V− - requiring careful attention to absolute maximum ratings (e.g., V+–V− ≤ 13.0V).
Signal integrity is maintained via low charge injection (1–5pC), low off-capacitance (2pF), and high off-isolation (<−90dB at 100kHz). Turn-on/off times are 40ns/15ns (dual ±5V) and 150ns/75ns (single +5V), supporting audio and medium-speed instrumentation switching without significant timing skew.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in precision sensor interfaces |
| On-resistance match (ΔRON) | 4Ω max between channels - critical for matched gain paths in differential or multi-channel ADC front-ends |
| On-resistance flatness | 12Ω max over rail-to-rail signal range - preserves linearity in audio and video signal routing |
| Off-leakage current | 10nA max at +85°C - enables low-drift performance in high-impedance sensor multiplexing |
| Logic thresholds | VIN_L = 0.8V, VIN_H = 2.4V - guarantees reliable switching with standard 5V TTL/CMOS control logic |
| ESD protection | >2kV per Method 3015.7 - provides robust handling in manufacturing and field-replaceable modules |
| Supply range | ±2V to ±6V dual or +2.7V to +12V single - supports portable, industrial, and avionics power architectures |
Pinout & Package
MAX4522ESE+ is housed in a 16-pin narrow SO (SOIC-N) package (S16-2), 3.9mm × 9.9mm body, 1.27mm pitch, with gull-wing leads. Pin 1 marked, exposed pad not present (non-QFN variant).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs - active-high logic drives corresponding NO switches ON |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path interface points for each switch |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog terminals - connect to COM only when IN = HIGH; no internal connection when OFF |
| 4 | GND | Digital ground reference - separate from analog signal path; required for logic-level translator bias |
| 5 | V− | Negative analog supply - sets lower analog signal limit; tied to GND for single-supply operation |
| 12 | V+ | Positive analog/digital supply - powers internal logic and switch drivers; internally connected to substrate |
| 13 | N.C. | No connection - not internally bonded; must be left floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ - eliminates level-shifting in ±5V or +3.3V systems |
| Low on-resistance flatness | 12Ω max variation across full signal range - maintains amplitude fidelity in audio and instrumentation |
| Ultra-low power operation | <1µW typical supply current - extends battery life in portable test equipment and IoT edge nodes |
| PIN-compatible with DG211/DG212 | Direct footprint replacement in legacy designs - reduces redesign risk and qualification time |
| High off-isolation | <−90dB at 100kHz - prevents crosstalk between adjacent channels in multi-signal routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4522CSE+ | 0°C to +70°C operating range vs. −40°C to +85°C for MAX4522ESE+ | Not suitable for extended-temperature industrial or automotive environments | Select MAX4522ESE+ for designs requiring guaranteed operation down to −40°C or up to +85°C |
| ADG1412BRUZ | Higher on-resistance (1.8Ω typ), wider supply (±15V), but higher leakage (200pA typ @ 25°C) | Better for high-voltage industrial I/O; less optimal for ultra-low-leakage sensor muxing | Choose ADG1412BRUZ when ±15V operation or sub-nA leakage is required; MAX4522ESE+ preferred for low-cost, low-power, +5V/±5V systems |
Compared with MAX4522CSE+, the MAX4522ESE+ offers extended temperature reliability; compared with ADG1412BRUZ, it delivers significantly lower cost and power at the expense of voltage range and ultra-low leakage - making it optimal for consumer, portable, and cost-sensitive industrial analog routing.

FAQ
What is the maximum allowable V+ to V− differential voltage for MAX4522ESE+?
The absolute maximum V+ to V− differential voltage for MAX4522ESE+ is 13.0V. Exceeding this - even momentarily due to supply overshoot or noise - risks permanent damage. For example, ±6V supplies with ±10% tolerance reach 13.2V and must be derated or clamped. Always verify worst-case supply tolerances before system integration.
Does MAX4522ESE+ support single-supply operation below +2.7V?
No. MAX4522ESE+ is fully specified for single +2.7V operation and is not guaranteed below that voltage. At +2.5V, on-resistance increases significantly (e.g., ~600Ω typ at +2.7V drops to ~250Ω at +5V), and logic thresholds may become unreliable. Use only within the validated +2.7V to +12V single-supply range.
How does the pinout of MAX4522ESE+ differ from MAX4521ESE+?
MAX4522ESE+ uses NO (normally open) switches, so pins 3, 6, 11, and 14 are NO1–NO4. In contrast, MAX4521ESE+ uses NC (normally closed) switches at those same pins. All other pins (IN, COM, V+, V−, GND, N.C.) are identical - enabling direct PCB reuse if logic polarity and switch behavior are accounted for in firmware.
Can MAX4522ESE+ be used in a 50Ω RF signal path up to 50MHz?
Yes - MAX4522ESE+ maintains reasonably flat insertion loss up to 50MHz in 50Ω systems, as confirmed in Typical Operating Characteristics. However, off-isolation degrades above 10MHz (≈−52dB at 10MHz, worsening ~20dB/decade), so it is suitable for medium-frequency routing but not high-isolation RF switching.
Is the exposed pad present on MAX4522ESE+ in SO package?
No. The exposed pad (EP) is only present on QFN variants (e.g., MAX4522EGE). The MAX4522ESE+ uses a standard 16-pin narrow SOIC (S16-2) package without an exposed pad. Thermal dissipation relies on standard lead-frame conduction and PCB copper area under the body.
