Product details
Overview
MAX4522CEE+T 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 supplies, 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–+12V operation and is used in battery-powered data acquisition systems requiring low leakage and fast switching.
For engineers reviewing the MAX4522CEE+T datasheet, MAX4522CEE+T pinout, MAX4522CEE+T application, or MAX4522CEE+T equivalent, key selection criteria include on-resistance matching across four independent channels, TTL/CMOS-compatible logic thresholds at +5V supply, ESD robustness (>2kV per Method 3015.7), and QSOP-16 package compatibility with industry-standard DG212 footprints.
Technical Context
The MAX4522CEE+T implements four independent CMOS SPST switches with complementary N- and P-channel MOSFETs per channel, driven by level-translated logic inputs to ensure rail-to-rail analog conduction. Its internal architecture isolates digital control (V+, GND) from analog path (V+, V−), with reverse-biased ESD diodes clamping signals exceeding supply rails.
It operates across three supply configurations: bipolar (±2V to ±6V), single-ended (+2.7V to +12V), and fully specified down to +2.7V. Logic inputs meet TTL/CMOS thresholds (0.8V/2.4V) at ±5V or +5V supply, and all analog terminals support signals from V− to V+ without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal voltage drop and signal attenuation in precision analog paths |
| On-resistance match (ΔRON) | 4Ω max between channels - critical for matched gain/attenuation in multi-channel instrumentation |
| On-resistance flatness (RFLAT) | 12Ω max over signal range - maintains consistent insertion loss across rail-to-rail input voltages |
| Off-leakage current | 1nA at +25°C, 10nA at +85°C - preserves signal integrity in high-impedance sensor interfaces |
| Supply range | +2.7V to +12V single or ±2V to ±6V dual - enables direct integration into mixed-supply industrial and portable systems |
| Logic compatibility | TTL/CMOS thresholds (0.8V/2.4V) at +5V - eliminates need for level shifters when interfacing with standard microcontrollers |
| ESD protection | >2kV per Method 3015.7 - meets IEC 61000-4-2 Level 2 for robust handling in manufacturing and field environments |
Pinout & Package
MAX4522CEE+T is housed in a 16-pin QSOP (E16-4) package measuring 3.90mm × 4.90mm × 1.35mm, with gull-wing leads and 0.635mm pitch. The exposed pad variant is not used in this ordering code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-high logic drives NO switches ON (low impedance path between COMx and NOx) |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; bidirectional signal ports connected to NOx when corresponding INx = HIGH |
| 3, 6, 11, 14 | NO1–NO4 | Normally open analog terminals; only conduct to COMx when INx = HIGH; interchangeable with COMx |
| 4 | V− | Negative analog supply rail; must be tied to GND for single-supply operation; sets lower analog signal limit |
| 5 | GND | Digital ground reference; no analog signal reference - analog paths are floating between V+ and V− |
| 12 | V+ | Positive analog/digital supply; internally connected to substrate; powers logic and analog switch gates |
| 13 | N.C. | No internal connection; must remain unconnected on PCB to avoid parasitic coupling or latch-up risk |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping or distortion - essential for full-scale sensor and audio routing |
| Low power consumption | <1µW quiescent supply current - extends battery life in portable test equipment and IoT edge nodes |
| Pin compatibility with DG212 | Identical pinout and function to industry-standard DG212 - enables drop-in replacement without layout changes |
| Four independently controlled switches | Each INx controls one NOx–COMx path - allows flexible multiplexing, signal gating, or channel isolation in compact designs |
| High off-isolation | <−90dB at 100kHz - prevents crosstalk between inactive channels in sensitive measurement applications |
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 SO (S16-2); 3.9mm width vs. QSOP's 3.9mm, but longer body (9.9mm vs. 4.9mm) | Preferred where SOIC hand-soldering or legacy footprint reuse is required; slightly higher thermal resistance than QSOP | Select MAX4522CSE+ if board space allows larger package or existing SOIC assembly infrastructure is in place. |
| ADG1422BRUZ | Lower RON (2.6Ω typ), higher supply range (+3V to +40V), but higher leakage (20nA @ +85°C) and no DG212 pin compatibility | Better suited for high-voltage industrial PLC I/O modules; not drop-in for MAX4522CEE+T layouts due to different pin mapping | Choose ADG1422BRUZ only when ultra-low on-resistance or extended supply range outweighs footprint compatibility and leakage requirements. |
Compared with MAX4522CSE+, the MAX4522CEE+T offers identical switching performance in a smaller QSOP footprint ideal for space-constrained portable instruments; compared with ADG1422BRUZ, it trades higher RON for guaranteed pin compatibility, lower leakage, and proven interoperability with legacy DG212-based designs.

FAQ
What is the maximum analog signal voltage range supported by the MAX4522CEE+T?
The MAX4522CEE+T supports rail-to-rail analog signals from V− to V+. With ±5V dual supplies, this equals −5V to +5V; with +5V single supply (V− = GND), it supports 0V to +5V. Absolute maximum ratings allow V+ up to +13.0V and V− down to −13.0V, but operational signal range remains bounded by the applied supplies. The MAX4522CEE+T maintains specified on-resistance flatness and leakage across this full range.
Is the MAX4522CEE+T pin-compatible with the DG212 analog switch?
Yes, the MAX4522CEE+T is explicitly designed as a pin-compatible replacement for the industry-standard DG212. Pin functions, numbering, and physical QSOP-16 footprint match exactly - including INx, COMx, NOx, V+, V−, GND, and N.C. connections. This allows direct substitution in existing DG212-based designs without PCB modifications or firmware changes.
What is the typical on-resistance flatness of the MAX4522CEE+T over temperature?
The MAX4522CEE+T guarantees ≤12Ω on-resistance flatness (RFLAT(ON)) over the full analog signal range at +25°C. Over the operating temperature range (0°C to +70°C), flatness degrades only modestly - typical curves show ≤18Ω variation at +70°C under ±5V supplies. This stability ensures consistent signal attenuation across temperature in precision measurement circuits using the MAX4522CEE+T.
Can the MAX4522CEE+T operate from a +3.3V single supply?
Yes, the MAX4522CEE+T is fully specified for single +2.7V operation and functions reliably at +3.3V. At V+ = +3.3V, typical on-resistance rises to ~350Ω (vs. 100Ω at ±5V), and turn-on time increases to ~250ns, but all logic thresholds, leakage limits, and rail-to-rail conduction remain valid. The MAX4522CEE+T is commonly deployed in +3.3V FPGA/CPU I/O expansion interfaces.
Does the MAX4522CEE+T require external pull-up or pull-down resistors on its INx pins?
No, the MAX4522CEE+T does not require external biasing on INx pins. Its digital inputs have defined TTL/CMOS-compatible thresholds (0.8V low, 2.4V high) and draw only ±1µA input current at +25°C. Direct connection to microcontroller GPIOs, FPGA outputs, or logic gates is sufficient. Adding external resistors may degrade switching speed or increase power - the MAX4522CEE+T is designed for direct logic interfacing.
