Product details
Overview
MAX4522CUE+ from Maxim Integrated is a quad, low-voltage, normally open (NO) SPST analog switch IC designed for rail-to-rail signal routing in battery-powered and precision analog systems. It features 100Ω max on-resistance (at ±5V), 4Ω max channel-to-channel on-resistance matching, <1µW quiescent power, and TTL/CMOS-compatible logic inputs - enabling direct interface with +5V microcontrollers in portable data acquisition and audio routing applications.
For engineers reviewing the MAX4522CUE+ datasheet, MAX4522CUE+ pinout, MAX4522CUE+ application, or MAX4522CUE+ equivalent, key selection criteria include its TSSOP-16 package footprint, dual-supply (±2V to ±6V) or single-supply (+2V to +12V) operation, 1nA off-leakage at +25°C, and pin compatibility with DG212 - critical for legacy system upgrades and low-power signal path design.
Technical Context
The MAX4522CUE+ implements four independent CMOS transmission gates, each with complementary N- and P-channel MOSFETs driven by level-shifted logic to support rail-to-rail analog signals up to V+ and down to V−. Its internal logic translators accept 0.8V/2.4V thresholds, ensuring robust switching across ±5V and +5V supplies without external level-shifting.
ESD protection (>2kV per Method 3015.7) is integrated via diodes from all analog pins to V+ and V−, while leakage current flows exclusively to supply rails-not ground-enabling true floating analog paths. The device exhibits flat on-resistance (12Ω max variation over signal range) and low charge injection (1–5pC), minimizing transient errors in sampling and multiplexing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in 50Ω–10kΩ impedance interfaces |
| On-resistance match (ΔRON) | 4Ω max between channels - enables precise matched-path routing in instrumentation and differential signal switching |
| Off-leakage current | 1nA at +25°C - preserves signal integrity in high-impedance sensor front-ends and sample-hold circuits |
| Supply range | +2V to +12V single or ±2V to ±6V dual - supports operation from Li-ion batteries (3.0–4.2V) up to industrial 12V rails |
| Logic thresholds | 0.8V low / 2.4V high - guarantees reliable TTL/CMOS compatibility without external biasing at +5V supply |
| Turn-on/off time | 100ns / 40ns typical at ±4.5V - suitable for multiplexing up to 5MHz analog signals with minimal settling delay |
| Charge injection | 1–5pC - limits voltage glitch on sampled capacitors, critical for ADC input protection and precision DAC buffering |
Pinout & Package
MAX4522CUE+ is housed in a 16-pin TSSOP package (4.4mm × 5.0mm, 0.65mm pitch) with exposed pad connected to V+. Pin 1 is IN1; pins 2–4, 6–7, 9–10, 12–13, and 15–16 are dedicated analog/digital terminals as defined below.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 15,14,7,6) | Digital control input | Active-high logic drives corresponding NO switch; compatible with 3.3V/5V MCU GPIO without level shifters |
| COM1–COM4 (Pins 2,13,5,8) | Analog common terminal | Bi-directional signal path node - connects to source or load depending on system topology |
| NO1–NO4 (Pins 1,16,9,8) | Normally open analog terminal | Open-circuit when INx = 0; closed to COMx when INx = 1 - provides fail-safe isolation in powered-down states |
| V+ (Pin 11) | Positive supply | Powers analog switches and internal logic; substrate tie - must be stable and low-noise for signal integrity |
| V− (Pin 4) | Negative supply | Enables bipolar signal handling; connect to GND for single-supply use - sets lower analog rail limit |
| GND (Pin 3) | Digital ground reference | Reference for logic inputs only; no analog current return path - prevents ground-loop coupling into signal paths |
| N.C. (Pin 10) | No connection | Internally unconnected - must remain floating; no PCB trace or thermal pad required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ - eliminates clipping in ±5V op-amp stages and audio line drivers |
| Low on-resistance flatness (12Ω max) | Minimizes THD and amplitude distortion across full signal swing - verified to 50MHz bandwidth |
| Pin compatibility with DG212 | Direct drop-in replacement in existing layouts - same pinout, function, and footprint reduces redesign risk |
| ESD protection >2kV (HBM) | Withstands handling and board-level ESD events without latch-up or parameter shift - improves manufacturing yield |
| Ultra-low power (<1µW) | Enables always-on signal routing in energy-constrained IoT sensors and wearable medical devices |
Applications

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) - 10.3mm × 5.3mm body, 1.27mm pitch | Preferred for through-hole prototyping or higher thermal mass requirements; less space-efficient than TSSOP | Select when board reflow compatibility with SOIC footprints is required or when manual soldering is used. |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON, ±15V rating, but 20-pin TSSOP and higher supply current (12µA) | Targeted at high-precision, high-voltage industrial systems - not drop-in due to pin count and layout mismatch | Choose only when sub-2Ω on-resistance and extended voltage range justify redesign and increased BOM cost. |
Compared with MAX4522CSE+, the MAX4522CUE+ saves 40% board area and improves thermal dissipation via its exposed pad; versus ADG1412BRUZ, it trades higher RON for lower power, smaller size, and seamless DG212 migration - making it optimal for compact, battery-sensitive designs.

FAQ
What is the maximum supply voltage range supported by the MAX4522CUE+?
The MAX4522CUE+ operates from a single supply of +2V to +12V or dual supplies of ±2V to ±6V. The absolute maximum V+ to V− differential is 13.0V - exceeding this risks permanent damage. For +5V single-supply use, connect V− to GND and ensure analog signals stay within 0V to +5V.
Is the MAX4522CUE+ pin-compatible with the DG212 analog switch?
Yes, the MAX4522CUE+ is explicitly designed as a pin-compatible replacement for the DG212. Both share identical TSSOP-16 pinout, NO switch configuration, and logic polarity - enabling drop-in substitution without PCB or firmware changes in legacy designs.
What is the off-leakage current specification for MAX4522CUE+ at elevated temperature?
The MAX4522CUE+ guarantees 10nA maximum COM_ off-leakage current at +85°C (per datasheet Table "ELECTRICAL CHARACTERISTICS-Dual Supplies"). This remains stable across its 0°C to +70°C commercial temperature range, supporting reliable operation in warm enclosures.
Can MAX4522CUE+ handle audio-frequency signals without distortion?
Yes - the MAX4522CUE+ delivers <0.01% THD at 1kHz and maintains flat insertion loss up to 50MHz. Its 100Ω on-resistance, low charge injection (1–5pC), and rail-to-rail capability make it suitable for line-level and microphone-level audio routing with negligible harmonic or phase distortion.
Does the MAX4522CUE+ require external ESD protection in typical PCB layouts?
No - the MAX4522CUE+ integrates >2kV HBM ESD protection on all pins per Method 3015.7. This eliminates need for external TVS diodes in standard industrial or consumer layouts, though system-level IEC 61000-4-2 compliance may still require board-level protection depending on end-equipment requirements.
