Product details
Overview
MAX4852ETE+ from Maxim Integrated is a dual SPDT analog switch optimized for USB 2.0 full-speed (12Mbps) signal routing and audio-path switching in portable electronics. It operates from a single +2V to +5.5V supply, delivers 3.5Ω/7Ω on-resistance, supports over-rail signals up to 5.5V, and draws only 1µA supply current - enabling low-power headphone jack detection and data path selection in cellular phones and notebook computers.
For engineers reviewing the MAX4852ETE+ datasheet, MAX4852ETE+ pinout, MAX4852ETE+ application, or MAX4852ETE+ equivalent, key selection criteria include over-rail signal pass-through capability, sub-1ns differential skew for USB D+/D− integrity, 135MHz −3dB bandwidth, 1µA quiescent current, and TQFN-16 (3mm × 3mm) package compatibility with space-constrained handheld designs.
Technical Context
The MAX4852ETE+ implements two independent SPDT analog switches without integrated comparators - distinguishing it from the MAX4850 series. Its architecture supports bidirectional signal routing with rail-to-rail analog input range (0V to 5.5V) and logic-compatible digital control inputs (1.4V VIH min at VCC = 2V; 1.8V VIH min at VCC ≥ 3.6V).
Unlike the H-variant (MAX4852H), the MAX4852ETE+ uses pass-through over-rail handling: signals exceeding VCC are transmitted without distortion or high-impedance interruption. Its 3.5Ω/7Ω dual-channel on-resistance pairing enables asymmetric load matching - e.g., low-RON for critical signal paths and higher-RON for auxiliary functions - while maintaining <0.25Ω on-resistance match across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | +2.0V to +5.5V - supports direct integration with Li-ion battery rails (2.7–4.2V) and 3.3V/5V system domains without level shifters. |
| On-Resistance | 3.5Ω (Channel 1), 7Ω (Channel 2) at VCC = 3V - enables low insertion loss for USB data lines and minimal THD (<0.04%) in audio paths. |
| −3dB Bandwidth | 135MHz - preserves signal integrity for USB 2.0 full-speed (12Mbps) eye diagrams and wideband audio signals up to 20kHz. |
| Differential Skew | 0.1ns typical - ensures matched propagation delay between D+ and D− paths, critical for USB timing compliance and EMI reduction. |
| Supply Current | 1µA at VCC = 5.5V - allows always-on USB detection or audio jack sensing in battery-powered devices without measurable drain. |
| Analog Signal Range | 0V to +5.5V - permits pass-through of biased audio signals (e.g., VCC/2 DC offset) and USB voltage levels even when VCC = 2.0V. |
| Logic Compatibility | 1.8V-input compatible - accepts standard low-voltage GPIO outputs directly, eliminating external translators in modern SoC interfaces. |
Pinout & Package
MAX4852ETE+ is housed in a 16-pin, 3mm × 3mm, 0.8mm-thick TQFN-EP package with exposed paddle (EP) for thermal and electrical grounding. Pin 1 is located at top-left per JEDEC MO-220; EP must be soldered to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 8, 11, 13 | No Connection (NC) | Unbonded die pads - no internal connection; must remain unconnected on PCB. |
| 4 | COM1 | Common terminal for Switch 1 - bidirectional node connected to either NO1 or NC1 based on IN1 logic state. |
| 5 | NO1 | Normally Open terminal for Switch 1 - connects to COM1 only when IN1 = HIGH (logic 1). |
| 6 | GND | Ground reference - primary return path for analog signals and supply current; ties to EP for lowest impedance. |
| 7 | NC2 | Normally Closed terminal for Switch 2 - connects to COM2 when IN2 = LOW (logic 0). |
| 9 | IN2 | Digital control input for Switch 2 - TTL/CMOS-compatible; drives switch state without external pull-ups. |
| 10 | COM2 | Common terminal for Switch 2 - bidirectional node routed to NC2 (IN2 = 0) or NO2 (IN2 = 1). |
| 12 | NO2 | Normally Open terminal for Switch 2 - connects to COM2 only when IN2 = HIGH. |
| 14 | VCC | Positive supply - requires local 0.01µF ceramic bypass capacitor to GND for stable switching performance. |
| 15 | IN1 | Digital control input for Switch 1 - independent of IN2; enables asynchronous routing control for dual-path applications. |
| 16 | NC1 | Normally Closed terminal for Switch 1 - connects to COM1 when IN1 = LOW. |
| EP | Exposed Paddle | Thermal and electrical ground - must be soldered to solid copper ground plane for thermal dissipation and noise immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4852HETE+ | Same pinout and dual SPDT topology, but uses high-impedance over-rail mode (not pass-through) - input disconnects when signal exceeds VCC. | Suitable for systems requiring fault isolation during over-voltage transients (e.g., hot-plug USB), not for continuous over-rail signal transmission. | Select MAX4852HETE+ only if high-Z fail-safe behavior is required; MAX4852ETE+ is preferred for uninterrupted signal routing. |
| TS5A23157DGSR | Single-supply 2.3–5.5V operation, 0.9Ω typical RON, but lacks over-rail capability and has 12ns tON/tOFF vs. 30ns for MAX4852ETE+. | Better for low-RON precision analog paths where over-rail signals are absent; unsuitable for USB 2.0 full-speed due to higher skew and no over-rail support. | Choose TS5A23157DGSR for ultra-low-loss audio line switching; use MAX4852ETE+ when over-rail USB/data routing is mandatory. |
Compared with MAX4852HETE+, the MAX4852ETE+ provides uninterrupted signal pass-through above VCC - essential for USB and biased audio. Against TS5A23157DGSR, it trades lower RON for guaranteed over-rail operation and USB-timed skew, making it uniquely suited for portable data/audio convergence.

FAQ
What is the over-rail signal handling behavior of the MAX4852ETE+?
The MAX4852ETE+ uses pass-through over-rail handling: analog signals up to +5.5V are transmitted without distortion or interruption even when VCC is as low as +2.0V. Unlike the H-variant, it does not enter high-impedance mode - ensuring continuous signal integrity for USB D+/D− and biased audio paths in battery-operated devices.
Does the MAX4852ETE+ support USB 2.0 full-speed signaling?
Yes, the MAX4852ETE+ is explicitly designed for USB 2.0 full-speed (12Mbps) applications. Its 135MHz −3dB bandwidth, 0.1ns differential skew, and 3.5Ω/7Ω on-resistance preserve signal eye diagrams and meet USB timing budgets. The device routes D+ and D− simultaneously with matched propagation delay to avoid data corruption.
What is the supply current specification for MAX4852ETE+ at different voltages?
The MAX4852ETE+ draws only 1µA typical supply current across its full operating range (+2.0V to +5.5V). This ultra-low quiescent current is confirmed at VCC = 5.5V and TA = +25°C, and remains stable over temperature (−40°C to +85°C), enabling always-on USB detection and audio jack sensing in battery-powered designs without measurable impact on runtime.
Can the MAX4852ETE+ be used for audio signal routing with low distortion?
Yes, the MAX4852ETE+ delivers 0.04% total harmonic distortion (THD) at 20Hz–20kHz with 600Ω load, enabled by its low 3.5Ω/7Ω on-resistance, flat RON vs. voltage profile, and 50pF on-capacitance. Its bidirectional operation and rail-to-rail analog range (0V to 5.5V) support both AC-coupled and DC-biased audio paths in smartphones and notebooks.
What package type and thermal requirements apply to MAX4852ETE+?
The MAX4852ETE+ uses a 16-pin TQFN-EP package (3mm × 3mm × 0.8mm) with exposed paddle. The EP must be soldered to a solid PCB ground plane for thermal dissipation and noise immunity. With 1667mW max power dissipation at TA = +70°C and 20.8mW/°C derating above that, it supports continuous operation in handheld enclosures without heatsinking.
