Product details
Overview
The MAX4764ETB+TGA8 from Maxim Integrated is a dual SPDT analog switch optimized for low-distortion audio routing in portable electronics. It supports ±5.5V signal swing below ground (down to VCC − 5.5V), delivers 0.6Ω on-resistance at +2.7V, features internal shunt switches to suppress click/pop, and operates from +1.8V to +5.5V - making it ideal for headphone jack switching in smartphones and MP3 players.
For engineers reviewing the MAX4764ETB+TGA8 datasheet, MAX4764ETB+TGA8 pinout, MAX4764ETB+TGA8 application, or MAX4764ETB+TGA8 equivalent, key selection criteria include negative rail capability, shunt-enabled clickless switching, on-resistance matching (±0.05Ω), THD (0.01%), and TDFN-10 package compatibility with space-constrained PCB layouts.
Technical Context
This device implements break-before-make switching with <7ns delay to prevent signal shorting during state transitions. Its BiCMOS process enables ultra-low on-resistance flatness (0.25Ω) and tight channel-to-channel matching (0.05Ω), critical for stereo audio path consistency.
The integrated 100Ω shunt switch automatically discharges NC/NO node capacitance when unconnected to COM, eliminating DC step-induced transients. Signal paths are fully bidirectional, supporting both source-to-load and load-to-source configurations without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | VCOM/VNO/VNC = VCC − 5.5V to VCC: enables distortion-free passage of signals below ground (e.g., AC-coupled audio with negative excursions) |
| On-Resistance (RON) | 0.6Ω typical at +2.7V: minimizes insertion loss and thermal drift in high-fidelity audio paths |
| On-Resistance Matching | ±0.05Ω max: ensures identical gain/attenuation across left/right stereo channels |
| Off-Isolation | −65dB at 100kHz: prevents crosstalk between active and inactive audio sources |
| Total Harmonic Distortion | 0.01% at 20Hz–20kHz: preserves audio fidelity in consumer-grade playback systems |
| Supply Voltage Range | +1.8V to +5.5V: supports direct interface with Li-ion battery rails (2.7–4.2V) and 3.3V/5V system logic |
Pinout & Package
MAX4764ETB+TGA8 uses a 10-pin TDFN package (3.0mm × 3.0mm × 0.8mm) with exposed pad (EP) for thermal dissipation. Pin 1 is VCC, pin 6 is GND, and EP must be soldered to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Positive supply input | Accepts +1.8V to +5.5V; powers analog switch core and control logic |
| NO1 (Pin 2) | Analog switch 1 normally open terminal | Connects to COM1 when IN1 = HIGH; used for primary audio path selection |
| COM1 (Pin 3) | Analog switch 1 common terminal | Bidirectional I/O node; routes signal between NO1 and NC1 based on IN1 logic state |
| NC1 (Pin 4) | Analog switch 1 normally closed terminal | Connects to COM1 when IN1 = LOW; provides default audio path before activation |
| IN1 (Pin 5) | Digital control input for switch 1 | Logic-compatible with 1.8V–5.5V inputs; no level-shifting required in mixed-voltage systems |
| GND (Pin 6) | Ground reference | Return path for analog signals and supply current; ties to EP for thermal stability |
| IN2 (Pin 7) | Digital control input for switch 2 | Independent control of second SPDT channel; enables stereo or dual-source routing |
| NC2 (Pin 8) | Analog switch 2 normally closed terminal | Provides redundant or alternate path for second audio channel |
| COM2 (Pin 9) | Analog switch 2 common terminal | Second bidirectional node; mirrors COM1 functionality for parallel channel operation |
| NO2 (Pin 10) | Analog switch 2 normally open terminal | Activates on IN2 HIGH; completes stereo pair or dual-input selection |
Key Features
| Feature | Design Value |
|---|---|
| Negative rail capability | Supports analog signals down to VCC − 5.5V, enabling true bipolar audio handling without external biasing |
| Integrated shunt switch | 100Ω discharge path on NC/NO nodes eliminates residual voltage buildup, reducing audible click/pop by >20dB |
| Break-before-make timing | <7ns guaranteed delay prevents momentary shorting between audio sources during switching |
| Bidirectional signal flow | COM/NO/NC pins function identically as inputs or outputs, simplifying PCB layout for reversible audio paths |
| Low THD and crosstalk | 0.01% THD and −70dB crosstalk ensure channel separation and minimal harmonic artifacts in stereo applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT audio switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4764AETB | Same pinout and shunt functionality; improved VIH/VIL thresholds (1.6V/0.5V) for 1.8V logic compatibility | Better suited for 1.8V-only microcontroller interfaces; identical audio performance | Select MAX4764AETB when driving IN1/IN2 directly from 1.8V GPIO without level translation |
| TS5A23157DCUR | 0.9Ω RON, no shunt switch, −40°C to +85°C, same TDFN-10 package | Lacks click/pop suppression; requires external RC snubbers for audio switching | Choose TS5A23157DCUR only if shunt functionality is unnecessary and cost is primary constraint |
Compared with MAX4764AETB, the MAX4764ETB+TGA8 offers identical switching performance but requires higher logic-high threshold (1.4V at 2.7V supply); versus TS5A23157DCUR, it delivers superior audio fidelity via integrated shunt discharge and lower RON, justifying use in premium portable audio designs.

FAQ
What is the maximum allowable analog signal voltage range for MAX4764ETB+TGA8?
The MAX4764ETB+TGA8 supports analog signals from VCC − 5.5V to VCC. For example, with a +3.3V supply, signals from −2.2V to +3.3V pass without distortion. This negative rail capability eliminates need for external DC biasing in AC-coupled audio circuits, and the MAX4764ETB+TGA8 maintains <0.01% THD across this full range at 20Hz–20kHz.
Does MAX4764ETB+TGA8 include an integrated shunt switch, and how does it function?
Yes, the MAX4764ETB+TGA8 integrates a 100Ω shunt switch on each NO and NC terminal. When a switch channel is off, this shunt automatically discharges residual capacitance at the unconnected node, preventing DC voltage buildup that causes audible click/pop during audio source switching. The MAX4764ETB+TGA8's shunt operates without external components or control signals, reducing BOM count and PCB area.
What is the on-resistance matching specification for MAX4764ETB+TGA8, and why does it matter?
The MAX4764ETB+TGA8 guarantees on-resistance matching of ±0.05Ω between its two SPDT channels. This tight matching ensures identical insertion loss and phase response across left/right stereo paths, preserving channel balance and stereo imaging accuracy. In practice, this means ≤0.02dB gain error between channels - a critical requirement for high-fidelity portable audio where perceptible imbalance degrades user experience. The MAX4764ETB+TGA8 achieves this via matched BiCMOS transistor design and on-die trimming.
Can MAX4764ETB+TGA8 be controlled directly by a 1.8V microcontroller GPIO without level shifting?
Yes, the MAX4764ETB+TGA8 accepts logic inputs from 1.8V to 5.5V regardless of VCC level. At VCC = +2.7V, VIH is 1.4V and VIL is 0.5V, so a 1.8V GPIO (HIGH ≈ 1.8V, LOW ≈ 0V) meets specifications with margin. This allows direct interface with low-voltage MCUs in space-constrained designs. The MAX4764ETB+TGA8 also supports mixed-voltage systems - e.g., 3.3V VCC with 5V logic inputs - without external translators.
What package type and thermal characteristics does MAX4764ETB+TGA8 use?
The MAX4764ETB+TGA8 uses a 10-pin TDFN package (3.0mm × 3.0mm × 0.8mm) with exposed thermal pad (EP). At TA = +70°C, it delivers 1951mW continuous power dissipation, derating by 24.4mW/°C above that temperature. The EP must be soldered to a PCB ground plane for optimal thermal performance. This compact footprint supports high-density portable designs while maintaining thermal reliability under sustained 100mA channel current loads - well within the MAX4764ETB+TGA8's ±150mA absolute maximum rating.
