Product details
Overview
The NCX8200UKZ from NXP Semiconductors is an audio jack configuration switch matrix IC designed to dynamically reconfigure ground and microphone-bias paths between AHJ and OMTP headset standards. It features ultra-low RDS(on) (57 mΩ GRD switch at 3.6 V), 8 kV HBM ESD protection, and operates from 1.6 V to 3.6 V supply. It enables dual-standard headset support in smartphones and portable media players.
For engineers reviewing the NCX8200UKZ datasheet, NCX8200UKZ pinout, NCX8200UKZ application, or NCX8200UKZ equivalent, key selection criteria include AHJ/OMTP auto-detection capability, quasi-differential GND sense path support, THD < 0.005%, and WLCSP9 package compatibility with space-constrained PCB layouts.
Technical Context
The NCX8200UKZ implements a dual-path analog switch matrix controlled by a single SEL input, enabling hardware-selectable routing of CON1/CON2 to GND and MIC to either contact while switching the Sense path between SNS1 and SNS2. Its internal 750 kΩ pull-down on SEL ensures default AHJ-compliant configuration at power-up.
It integrates three independent switch channels - GRD (ground return), MIB (microphone bias), and SNS (GND sense) - each optimized for low on-resistance flatness (<50 mΩ variation across voltage range) and high PSRR (−80 dB for MIB, −60 dB for GRD), supporting clean audio signal integrity in noisy mobile environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.6 V to 3.6 V - supports direct connection to single-cell Li-ion or LDO outputs without level-shifting |
| GRD Switch RON | 57–120 mΩ - ensures minimal voltage drop and thermal rise under 100 mA headset ground current |
| MIB Switch RON | 0.46–2.5 Ω - maintains stable microphone bias voltage across battery discharge cycle |
| THD (MIB Path) | 0.005% - preserves microphone signal fidelity without harmonic distortion in voice capture |
| PSRR (MIB) | −80 dB - rejects power supply ripple that could modulate microphone output |
| ESD Protection | 8 kV HBM - meets IEC 61000-4-2 Level 4 for robustness against user-handling events |
| Ambient Temp Range | −40 °C to +85 °C - qualified for operation in consumer handheld devices under real-world thermal conditions |
Pinout & Package
NCX8200UKZ uses a 1.22 mm × 1.22 mm × 0.5 mm WLCSP9 package with face-down solder bumps. The die is mounted with index area at A1 corner; bump pitch is 0.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SNS1 (A1) | Analog sense path 1 | Connects to headset jack GND when SEL = L; enables quasi-differential amplifier topology |
| Sense (A2) | GND sensing input | Reference node for detecting headset jack insertion and grounding state |
| SNS2 (A3) | Analog sense path 2 | Connects to headset jack GND when SEL = H; completes dual-sense architecture |
| CON1 (B1) | Headset jack pin 1 | Routed to GND (AHJ) or MIC (OMTP) based on SEL logic state |
| SEL (B2) | Configuration select input | Logic-controlled switch mode selector; internal 750 kΩ pull-down sets default AHJ mode |
| CON2 (B3) | Headset jack pin 2 | Routed to MIC (AHJ) or GND (OMTP); complements CON1 routing |
| VDD (C1) | Core supply | Accepts 1.6–3.6 V; requires ≥1 µF local bypass capacitor for stable switching |
| GND (C2) | Ground reference | Primary system ground return; all internal switches reference this node |
| MIC (C3) | Microphone bias connection | Interface point to audio codec's MIC bias rail; passes bias with ultra-low THD |
Key Features
| Feature | Design Value |
|---|---|
| AHJ/OMTP dual-standard support | Hardware-selectable pinout routing eliminates need for software-based jack detection firmware |
| Quasi-differential GND sense path | Enables accurate ground reference sensing for noise-cancelling headsets with differential amplifiers |
| Ultra-low RON flatness | ≤50 mΩ variation across 1.8–3.6 V supply ensures consistent audio channel performance during battery discharge |
| High PSRR (−80 dB) | Prevents power rail noise from modulating microphone signal, critical for voice call clarity |
| WLCSP9 footprint | 1.22 mm² area minimizes PCB real estate use in ultra-thin mobile designs without sacrificing thermal performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar audio jack configuration switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14522ETA+ | Supports only OMTP standard; lacks AHJ mode and dual-sense path; higher RON (1.2 Ω MIB at 3.0 V) | Requires separate AHJ detection circuitry; not suitable for universal dual-standard designs | Select only if OMTP-only support suffices and board space allows larger TDFN package |
| TS5A23157DCUR | General-purpose SPDT analog switch; no integrated GND sense path, no AHJ/OMTP logic, no ESD rating above 2 kV | Needs external ESD protection and microcontroller-driven mode selection logic | Use only for custom jack detection systems where full control over routing and timing is required |
Compared with MAX14522ETA+ and TS5A23157DCUR, the NCX8200UKZ uniquely integrates AHJ/OMTP auto-selection, dual GND sense paths, and 8 kV ESD protection in a 1.22 mm² WLCSP, reducing system-level complexity and component count for universal headset interface designs.

FAQ
What headset standards does the NCX8200UKZ support?
The NCX8200UKZ supports both American Headset Jack (AHJ) and Open Mobile Terminal Platform (OMTP) pinouts via hardware-selectable routing controlled by the SEL pin. When SEL is low, it configures for AHJ (CON1 = GND, CON2 = MIC); when high, it configures for OMTP (CON1 = MIC, CON2 = GND). This eliminates the need for software-based detection algorithms in the host system.
How does the NCX8200UKZ handle ground sensing for quasi-differential amplifier architectures?
The NCX8200UKZ provides two dedicated analog sense paths - SNS1 and SNS2 - that route to headset jack GND depending on SEL state, while the Sense pin serves as the common GND sensing input. This enables true quasi-differential measurement by referencing the active sense path against the headset's physical ground, improving noise rejection in high-fidelity audio applications using the NCX8200UKZ.
What is the maximum continuous current rating for the ground switch in the NCX8200UKZ?
The ground switch (GRD channel) in the NCX8200UKZ is rated for 100 mA continuous current from CON1 or CON2 to GND, as specified in Table 4 (Limiting Values). This rating holds across the full operating temperature range (−40 °C to +85 °C) and ensures reliable operation with typical headset ground return loads without thermal derating.
Does the NCX8200UKZ require external passive components for basic operation?
Yes - the NCX8200UKZ requires a minimum 1 µF bypass capacitor between VDD and GND placed close to the device, as stated in Section 9 (Application Diagram). This capacitor stabilizes the internal supply during switching transients. No external resistors or capacitors are needed for SEL logic, as the device integrates a 750 kΩ internal pull-down resistor.
Is the NCX8200UKZ qualified for automotive applications?
No - the NCX8200UKZ is not automotive-qualified. Per Section 18.3 of the datasheet, unless explicitly stated as automotive qualified, the device is intended for consumer portable electronics only. It has not been tested or certified to AEC-Q100 standards, and NXP disclaims liability for use in safety-critical or life-support systems including automotive infotainment head units.
