Product details
Overview
MAX4522CPE+ 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 12Ω max on-resistance flatness over the full signal range. Each of its four independently controlled switches supports dual supplies (±2V to ±6V) or single +2.7V to +12V operation - enabling use in battery-powered data acquisition front-ends.
For engineers reviewing the MAX4522CPE+ datasheet, MAX4522CPE+ pinout, MAX4522CPE+ application, or MAX4522CPE+ equivalent, key selection criteria include verified rail-to-rail analog handling, <1nA off-leakage at +25°C, TTL/CMOS-compatible logic thresholds, ESD robustness (>2kV per Method 3015.7), and pin compatibility with DG211/DG212/DG213 legacy switches.
Technical Context
The MAX4522CPE+ implements four independent CMOS transmission gates, each formed by paralleled N- and P-channel MOSFETs driven by phase-inverted V+ and V− signals via internal level translators. Its analog path operates without ground reference - signal limits are strictly bounded by V+ and V−, with internal ESD diodes clamping any excursion beyond those rails.
Logic inputs accept 0.8V/2.4V thresholds for guaranteed TTL/CMOS compatibility under ±5V or +5V supply conditions. Switching dynamics are characterized with 60ns typical turn-on and 20ns typical turn-off times (VCOM = ±3V, V± = ±4.5V), and charge injection is tightly controlled at 1–5pC, critical for sample-hold and multiplexer accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in precision gain-setting or sensor signal paths. |
| On-resistance match (ΔRON) | 4Ω max between channels - enables accurate channel-to-channel tracking in multi-channel instrumentation and calibration circuits. |
| On-resistance flatness (RFLAT) | 12Ω max over signal range - maintains consistent insertion loss across rail-to-rail input voltages, critical for audio and wide-dynamic-range ADC drivers. |
| Off-leakage current | 1nA at +25°C - preserves high-impedance node integrity in battery-operated sensor interfaces and low-power standby modes. |
| Supply range | +2.7V to +12V single or ±2V to ±6V dual - supports direct integration into 3.3V, 5V, and ±5V systems without level-shifting. |
| Logic compatibility | 0.8V/2.4V thresholds - guarantees reliable switching control from standard 5V TTL or CMOS microcontrollers and FPGAs. |
| ESD protection | >2kV per Method 3015.7 - provides robust handling during board assembly and field deployment in industrial environments. |
Pinout & Package
MAX4522CPE+ uses a 16-pin plastic DIP package (P16-1), 0.300" wide, with through-hole mounting. Pin 1 is NC (not connected); pins 2 and 5 are V− and GND respectively; pins 11 and 13 are V+ and COM2; all NO and COM terminals are fully interchangeable as bidirectional analog ports.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | NC (Not Connected) | No internal connection - must be left floating or tied to GND for mechanical stability; no electrical function. |
| 2, 15, 10, 7 | COM1–COM4 | Analog common terminal - bidirectional signal port; connects to load or source depending on system topology. |
| 3, 6, 14, 11 | NO1–NO4 | Normally open analog terminal - completes circuit only when corresponding INx = logic high; interchangeable with COMx. |
| 16, 13, 8, 5 | IN1–IN4 | Digital control input - active-high logic; drives internal level translators to enable respective NO–COM path. |
| 4 | V− | Negative analog supply - sets lower analog voltage limit; connect to GND for single-supply operation. |
| 5 | GND | Digital ground reference - separate from analog path; required for logic interface and substrate biasing. |
| 11 | V+ | Positive analog/digital supply - powers internal logic and switch drivers; internally connected to substrate. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping - eliminates need for external level-shifting in ±5V or 0–5V sensor/mux applications. |
| Low power consumption | <1µW quiescent - enables always-on monitoring in energy-constrained IoT nodes and portable test equipment. |
| Separately controlled SPST switches | Four independent logic-controlled paths - allows flexible signal routing, channel isolation, or redundant path selection in safety-critical systems. |
| Pin compatibility with DG211/DG212/DG213 | Drop-in replacement for legacy industry-standard switches - reduces redesign effort and qualification time in upgrade projects. |
| High off-isolation | <−90dB at 100kHz - suppresses crosstalk between adjacent channels in multi-channel data acquisition and audio routing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Single-supply only (+5V to +16.5V); 1.8Ω RON; higher 125°C max temp rating; SPI interface. | Requires digital control bus; better suited for high-temp industrial PLC I/O modules than battery-powered portable gear. | Select ADG1412BRUZ when SPI configurability and sub-2Ω RON outweigh need for dual-supply flexibility. |
| TS5A23157DGSR | Lower voltage range (+1.65V to +5.5V); 0.9Ω RON; smaller 10-pin VSSOP; no ESD rating specified. | Optimized for ultra-low-voltage mobile audio routing; lacks ±6V capability and documented ESD hardening for test equipment. | Select TS5A23157DGSR only for space-constrained 3.3V consumer audio designs where ESD robustness is secondary. |
Compared with ADG1412BRUZ and TS5A23157DGSR, MAX4522CPE+ uniquely supports true bipolar operation (±2V to ±6V), delivers verified >2kV ESD protection, and retains pin compatibility with legacy DG-series switches - making it the preferred choice for retrofitting and ruggedized instrumentation.

FAQ
What is the maximum allowable V+ to V− differential voltage for MAX4522CPE+?
The absolute maximum V+ to V− differential voltage for MAX4522CPE+ is 13.0V. Exceeding this - even momentarily due to supply overshoot or noise spikes - risks permanent damage. For example, ±6V supplies with ±10% tolerance reach 13.2V and must be derated or filtered before connecting to MAX4522CPE+.
Does MAX4522CPE+ support single-supply operation below +2.7V?
No. MAX4522CPE+ is fully specified down to +2.7V single supply (per Electrical Characteristics table). Operation at +2.5V or lower is not guaranteed - on-resistance increases sharply, logic thresholds become unreliable, and leakage may exceed datasheet limits. Use only within the validated +2.7V to +12V range.
Can COM and NO pins be swapped in circuit layout for MAX4522CPE+?
Yes. The MAX4522CPE+ datasheet explicitly states that NO and COM pins are identical and interchangeable - either may serve as input or output. This bidirectional capability simplifies PCB routing and enables flexible signal flow direction without redesigning the analog path topology.
Is MAX4522CPE+ pin-compatible with DG212 in the same DIP-16 footprint?
Yes. MAX4522CPE+ is documented as pin-compatible with DG211/DG212/DG213 in DIP-16 packages. Pin assignments for INx, COMx, NOx, V+, V−, and GND align directly - enabling drop-in replacement without PCB modification, provided supply and signal voltage ranges remain compatible.
What is the typical charge injection value for MAX4522CPE+ and why does it matter?
MAX4522CPE+ exhibits 1–5pC typical charge injection (Q), measured with CL = 1nF and RS = 0Ω. This parameter directly impacts settling time and residual offset in sample-and-hold circuits and multiplexed ADC front-ends - lower Q enables faster acquisition and reduced zero-error in precision measurement systems.
