Product details
Overview
MAX4653EGP from Maxim Integrated is a low-voltage, quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, 4Ω max on-resistance at +5V, 0.2Ω max on-resistance matching, and rail-to-rail signal handling capability. It operates from a single +1.8V to +5.5V supply and is used in precision audio routing and low-distortion data-acquisition front-ends.
For engineers reviewing the MAX4653EGP datasheet, MAX4653EGP pinout, MAX4653EGP application, or MAX4653EGP equivalent, key selection criteria include its dual NO/NC topology, 20-pin QFN (4×4 mm) package, break-before-make timing (1–6 ns), and −100 dB crosstalk at 1 MHz - critical for high-fidelity signal path integrity in battery-powered instrumentation.
Technical Context
The MAX4653EGP implements CMOS transmission-gate architecture with matched P/N channel pairs per switch, enabling flat on-resistance (<0.8Ω max variation over 0–V+ signal range at 5V) and low charge injection (2 pC typical). Its logic inputs are TTL/CMOS-compatible, supporting direct interfacing with microcontrollers without level-shifting.
Unlike the MAX4651 (4× NC) and MAX4652 (4× NO), the MAX4653EGP integrates mixed NO/NC topology in one die - enabling true break-before-make switching for fault-tolerant signal path selection in sample-and-hold and relay-replacement circuits without external sequencing logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 4Ω max at +5V - ensures minimal signal attenuation and voltage drop in precision analog paths. |
| On-resistance matching | 0.2Ω max between channels - enables accurate gain/phase matching in multi-channel signal routing. |
| Break-before-make time | 1–6 ns - prevents momentary shorting during channel switching in critical signal paths. |
| Crosstalk | −100 dB at 1 MHz - suppresses inter-channel interference in high-density audio/video routing. |
| Off-isolation | −75 dB at 1 MHz - maintains signal integrity by blocking leakage from inactive channels. |
| Supply voltage range | +1.8V to +5.5V - supports direct integration into Li-ion (3.3V/3.7V) and USB-powered systems. |
| Turn-on/turn-off time | 20 ns / 12 ns typ - enables fast multiplexing in high-speed data acquisition up to ~10 MSPS. |
Pinout & Package
MAX4653EGP is housed in a 20-pin QFN package (4 mm × 4 mm, 0.5 mm pitch) with exposed pad (EP) for thermal enhancement. The package is RoHS-compliant and rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-high TTL/CMOS-compatible logic signals controlling individual switch states. |
| COM1–COM4 | Analog common terminals | Signal input/output nodes shared between NO and NC paths per channel. |
| NO1, NO4 | Normally open analog terminals | Connected to COMx only when corresponding INx = high - used for default-open signal paths. |
| NC2, NC3 | Normally closed analog terminals | Connected to COMx when corresponding INx = low - provides fail-safe continuity in power-loss scenarios. |
| V+ | Positive supply | Single supply input (1.8–5.5V); powers internal switch drivers and logic interface. |
| GND | Ground reference | Return path for analog signals and digital logic; must be low-impedance for noise control. |
| N.C. | No connection | Unbonded pins (pins 5, 10, 11, 16, 17, 18, 19, 20 in 20-pin QFN) - left floating or grounded per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full-swing signals from GND to V+, eliminating clipping in ±2.5V or 0–5V systems. |
| Low off-leakage current | 0.1 nA max at +25°C - preserves accuracy in high-impedance sensor interfaces and sample-and-hold hold capacitors. |
| Flat on-resistance profile | 0.8Ω max variation across 0–V+ signal range at 5V - minimizes THD (<0.02%) in audio applications. |
| Low charge injection | 2 pC typical - reduces voltage glitch on hold capacitors, improving DC accuracy in data acquisition. |
| TTL/CMOS logic compatibility | VIH = 2.4V min, VIL = 0.8V max at 5V - allows direct drive from FPGAs, MCUs, and logic families without buffers. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4653ESE+ | 16-pin SOIC package (0.150" width), same electrical specs, no exposed thermal pad | Better suited for through-hole prototyping or legacy PCBs with SO footprint; lower thermal performance than QFN | Select for manual assembly, reworkability, or compatibility with existing SO-based layouts. |
| ADG1412BRUZ | Quad SPST, 1.8Ω RON max, 20-pin TSSOP, ±15V dual-supply capable | Requires dual supply for rail-to-rail operation; higher RON flatness (0.3Ω) but wider voltage range | Choose when bipolar signal handling (±10V) or lower on-resistance is prioritized over single-supply simplicity. |
Compared with MAX4653ESE+ and ADG1412BRUZ, the MAX4653EGP delivers optimal thermal performance and board-area efficiency in space-constrained, single-supply portable systems - while retaining identical switching characteristics and NO/NC functionality.

FAQ
What is the maximum operating temperature range for the MAX4653EGP?
The MAX4653EGP is specified for operation from −40°C to +85°C. This extended industrial temperature range ensures reliable performance in harsh environments such as factory automation equipment and outdoor portable instruments. All electrical parameters in the datasheet - including on-resistance, leakage, and switching times - are guaranteed across this full range.
Does the MAX4653EGP support rail-to-rail analog signal switching?
Yes, the MAX4653EGP supports rail-to-rail analog signal switching, meaning it can pass signals from GND to V+ without clipping or distortion. This capability is enabled by its CMOS transmission-gate architecture and is validated across the full supply range (+1.8V to +5.5V). The device maintains low THD (<0.02%) and flat on-resistance over the entire signal range.
How does the break-before-make timing work in the MAX4653EGP?
The MAX4653EGP guarantees break-before-make timing of 1–6 ns (typical 1 ns) between its NO and NC paths within each channel. This ensures that the NC path opens before the NO path closes during logic transitions, preventing momentary shorts in critical signal paths. This behavior is intrinsic to the internal switch driver design and requires no external timing circuitry.
Can the MAX4653EGP be used with a 3.3V supply?
Yes, the MAX4653EGP operates reliably from a +3.3V supply. At 3V, its on-resistance is 7Ω max, on-resistance flatness is 2.5Ω max, and logic thresholds adjust to VIH = 2.0V min / VIL = 0.4V max - fully compatible with standard 3.3V CMOS logic. Power supply current remains below 1 µA, making it ideal for ultra-low-power applications.
What is the function of the N.C. pins on the MAX4653EGP 20-pin QFN package?
The N.C. (no connection) pins on the MAX4653EGP 20-pin QFN - specifically pins 5, 10, 11, 16, 17, 18, 19, and 20 - are unconnected internally and serve no electrical function. They may be left floating or tied to GND for mechanical stability and improved solder joint reliability. These pins do not affect device operation or thermal performance when properly handled per Maxim's layout guidelines.
