Product details
Overview
MAX4723EBL from Maxim Integrated is a dual SPST analog switch with one normally open (NO) and one normally closed (NC) channel, designed for USB 1.1 signal routing and low-voltage audio switching. It operates from a single +1.8V to +5.5V supply, delivers 4.5Ω max on-resistance at +3V, <1ns break-before-make timing, and supports rail-to-rail analog signals in battery-powered portable equipment.
For engineers reviewing the MAX4723EBL datasheet, MAX4723EBL pinout, MAX4723EBL application, or MAX4723EBL equivalent, this device is selected for high-fidelity analog path integrity, low distortion (0.03%), minimal crosstalk (−80dB), and guaranteed operation across industrial temperature range (−40°C to +85°C) in space-constrained UCSP packaging.
Technical Context
The MAX4723EBL implements a BiCMOS-based dual-channel analog switch architecture with independent digital control inputs (IN1, IN2) enabling asynchronous switching of COM1/NO1 and COM2/NC2 paths. Its break-before-make timing (1ns) prevents momentary shorting during state transitions - critical for USB full-speed (12Mbps) data line protection.
It features rail-to-rail signal handling, +1.8V logic-compatible inputs (VIH = 1.4V at +3V supply), and bidirectional analog signal flow. The UCSP-9 package enables direct integration into compact audio codec interfaces and portable USB peripheral designs without compromising bandwidth (>300MHz −3dB) or leakage performance (<0.5nA at +25°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 4.5Ω at +3V supply - ensures minimal voltage drop and signal attenuation in low-voltage audio paths |
| Break-Before-Make Delay | 1ns - eliminates signal contention during dual-channel switching in USB D+/D− routing |
| −3dB Bandwidth | >300MHz - preserves integrity of USB 1.1 full-speed (12Mbps) and wideband audio signals |
| Off-Isolation | −55dB at 10MHz - suppresses coupling between active and inactive channels in mixed-signal systems |
| On-Channel Capacitance | 15pF - minimizes loading on high-impedance sources and maintains fast edge fidelity |
| Leakage Current (max) | ±1.5nA at TMIN to TMAX - enables stable DC-coupled sample-and-hold and precision sensor multiplexing |
| Supply Voltage Range | +1.8V to +5.5V - supports direct interfacing with Li-ion battery (3.0–4.2V), 3.3V logic, and 5V legacy peripherals |
Pinout & Package
MAX4723EBL is housed in a 1.52mm × 1.52mm chip-scale package (UCSP-9) with 3×3 bump array and 0.5mm bump pitch. This ultra-compact footprint reduces PCB area by >70% versus 8-pin µMAX, enabling placement adjacent to USB connectors or audio codecs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | IN2 | Digital control input for COM2/NC2 switch; compatible with +1.8V logic levels |
| A2 | GND | Digital ground reference; must be connected to system ground plane for noise immunity |
| A3 | NC2 | Normally closed analog terminal for second channel; connects to COM2 when IN2 = LOW |
| B1 | COM1 | Common analog node for first channel; bidirectional signal path shared with NO1 |
| B3 | COM2 | Common analog node for second channel; bidirectional signal path shared with NC2 |
| C1 | NO1 | Normally open analog terminal for first channel; connects to COM1 when IN1 = HIGH |
| C2 | V+ | Positive analog supply input; requires 0.1µF bypass capacitor to GND for stability |
| C3 | IN1 | Digital control input for COM1/NO1 switch; accepts up to +5.5V regardless of V+ level |
Key Features
| Feature | Design Value |
|---|---|
| USB 1.1 compliance | Guaranteed <2ns differential skew and <80ns tON at +2.7V - meets full-speed timing margin requirements |
| RON matching | 0.3Ω max between channels at +3V - enables precise gain-matched signal routing in stereo audio paths |
| Rail-to-rail signal handling | Analog range spans GND to V+ - supports unipolar/bipolar signal routing without level-shifting circuitry |
| Low distortion | 0.03% THD at +25°C - preserves fidelity in line-level and headphone driver signal chains |
| High off-isolation | −55dB at 10MHz - isolates active USB data lines from idle audio paths to prevent EMI coupling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4723EUA | Same electrical specs, but in 8-pin µMAX package (3.05mm × 3.05mm); no UCSP thermal/space constraints | Suitable for prototyping or higher-power designs where reworkability and thermal mass matter more than size | Select MAX4723EUA when board assembly uses standard reflow profiles and layout allows larger footprint. |
| TS5A23157DCUR | Lower RON (0.9Ω typ at 3V), but only NO/NO configuration; no NC channel; 1.5pF lower CON | Lacks NC functionality required for fail-safe or default-path applications like USB port protection | Choose TS5A23157DCUR only if both channels must be normally open and ultra-low capacitance is prioritized over redundancy. |
Compared with MAX4723EUA, the MAX4723EBL saves >75% board area but requires JEDEC-compliant IR reflow; compared with TS5A23157DCUR, it provides NC/NO flexibility essential for fault-tolerant USB routing but trades 1.2dB higher crosstalk at 10MHz.

FAQ
What is the maximum operating temperature range for the MAX4723EBL?
The MAX4723EBL is specified for continuous operation from −40°C to +85°C. This industrial temperature range is validated per Maxim's datasheet Section "Absolute Maximum Ratings" and applies to all electrical parameters including on-resistance, leakage current, and switching times. The UCSP-9 package maintains reliability within this range when assembled using JEDEC J-STD-020A-compliant reflow profiles.
Does the MAX4723EBL support rail-to-rail analog signal handling?
Yes, the MAX4723EBL supports rail-to-rail analog signal handling - its analog terminals (COM1, NO1, COM2, NC2) pass signals from GND to V+ without clipping or distortion. This capability is explicitly confirmed in the "Detailed Description" section and verified across all supply voltages (+1.8V to +5.5V) and temperatures in the "Typical Operating Characteristics" plots (e.g., RON vs. VCOM).
What is the function of the NC2 pin on the MAX4723EBL?
The NC2 pin on the MAX4723EBL is the normally closed analog terminal for the second switch channel. When IN2 is logic LOW, NC2 connects electrically to COM2; when IN2 is HIGH, the connection opens. This NO/NC dual configuration distinguishes MAX4723EBL from MAX4721 (NO/NO) and MAX4722 (NC/NC), enabling fail-safe or default-path routing in USB and audio applications.
Can the MAX4723EBL be used with a 1.8V logic supply while operating from a 3.3V analog supply?
Yes, the MAX4723EBL supports independent logic and analog supply domains: its digital inputs (IN1, IN2) are +1.8V logic compatible even when V+ = +3.3V, with VIH = 1.4V and VIL = 0.5V. This allows direct interface with 1.8V microcontrollers without level shifters - a key feature documented in the "Digital I/O" subsection of the Electrical Characteristics table.
What is the typical on-channel capacitance of the MAX4723EBL and why does it matter?
The MAX4723EBL has a typical on-channel capacitance of 15pF, measured at 1MHz. This low value minimizes capacitive loading on high-impedance sources (e.g., piezoelectric sensors or op-amp outputs), preserves signal rise/fall times in high-speed USB paths, and reduces crosstalk between adjacent traces - directly supporting its use in >300MHz bandwidth applications as verified in Figure 5a and the "Dynamic Characteristics" table.
