Product details
Overview
The MAX4693ETE+ from Maxim Integrated is a triple single-pole/double-throw (SPDT) analog switch IC designed for low-voltage signal routing in space-constrained systems. It operates from single +2V to +11V or dual ±2V to ±5.5V supplies, delivers 25Ω max on-resistance at ±4.5V, guarantees break-before-make switching, and supports rail-to-rail analog signal handling up to ±5.5V - ideal for audio path selection in portable communications equipment.
For engineers reviewing the MAX4693ETE+ datasheet, MAX4693ETE+ pinout, MAX4693ETE+ application, or MAX4693ETE+ equivalent, key selection criteria include guaranteed channel matching (≤3Ω max at ±4.5V), low 1nA leakage current, 90ns transition time, 1.8V logic compatibility at +3V supply, and TQFN-EP package thermal performance for battery-powered designs.
Technical Context
The MAX4693ETE+ implements three independent CMOS SPDT switches with separate digital control inputs (A, B, C) per channel, enabling simultaneous or individual switching of three bidirectional analog paths. Each switch features matched P- and N-channel MOSFETs driven by level-translated logic to ensure consistent RON across the full analog range (V− to V+).
It supports true bipolar operation: when powered from ±4.5V, it achieves 25Ω typical on-resistance, ≤3.5Ω flatness, and ≤3Ω channel-to-channel RON match - critical for precision instrumentation and balanced audio routing where gain/phase tracking matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | Single +2V to +11V or dual ±2V to ±5.5V - enables direct interface with Li-ion, USB, and industrial ±5V rails. |
| On-Resistance (max) | 25Ω at ±4.5V - ensures minimal signal attenuation and THD < 0.02% in audio paths. |
| RON Matching (max) | 3Ω at ±4.5V - maintains amplitude consistency across three switched channels in multi-path systems. |
| Leakage Current (max) | 20nA at +85°C - preserves DC accuracy in sensor front-ends and low-power standby modes. |
| Transition Time | 90ns - supports fast multiplexing in data acquisition and real-time signal conditioning. |
| Logic Compatibility | 1.8V-compatible at +3V supply - allows direct connection to modern ultra-low-voltage microcontrollers. |
| Off-Isolation | -82dB at 100kHz - suppresses crosstalk between inactive channels in high-density routing. |
Pinout & Package
The MAX4693ETE+ is housed in a 16-pin TQFN-EP (3mm × 3mm) package with exposed pad for enhanced thermal dissipation. Pin numbering follows standard JEDEC TQFN layout (pin 1 top-left, counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A (Pin 4) | X-switch control input | Drives X0/X1 SPDT; logic high connects X to X1, low connects X to X0. |
| B (Pin 5) | Y-switch control input | Drives Y0/Y1 SPDT; independent of A and C for parallel channel control. |
| C (Pin 3) | Z-switch control input | Drives Z0/Z1 SPDT; enables fully independent triple-switch operation. |
| X (Pin 13) | X-switch common terminal | Bidirectional analog node shared between X0 and X1; handles rail-to-rail signals. |
| Y (Pin 15) | Y-switch common terminal | Independent common for Y-path; electrically isolated from X and Z nodes. |
| Z (Pin 7) | Z-switch common terminal | Third isolated common; supports three simultaneous analog signal paths. |
| V+ (Pin 6) | Positive supply | Powers analog switches and internal logic; must be bypassed with 0.1µF capacitor. |
| V− (Pin 14) | Negative supply | Required for dual-supply operation; connect to GND for single-supply mode. |
| GND (Pin 2) | Digital ground reference | Reference for EN and address logic; no analog ground connection required. |
| EN (Pin 10) | Global enable | Active-low; drives all three switches open when high - provides system-level power gating. |
| X0/X1 (Pins 12/11) | X-switch NC/NO inputs | Normally closed (X0) and normally open (X1) terminals; bidirectional signal paths. |
| Y0/Y1 (Pins 16/1) | Y-switch NC/NO inputs | Electrically identical to X-path but isolated; supports differential or independent routing. |
| Z0/Z1 (Pins 8/9) | Z-switch NC/NO inputs | Third isolated SPDT pair; enables triple-path redundancy or multi-source selection. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Ensures no momentary short between NC and NO paths during switching - prevents signal glitches in audio/video routing. |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±5V op-amp interfaces and unbuffered sensor outputs. |
| Low 1nA leakage current | Maintains high-impedance integrity in battery-powered standby states and precision measurement front-ends. |
| 3.5Ω max RON flatness | Minimizes distortion across full signal swing - critical for THD-sensitive applications like audio codecs. |
| 16-pin TQFN-EP package | 3mm × 3mm footprint with exposed pad reduces PCB area by >50% vs. SOIC while improving thermal resistance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4693EBE+ | Same electrical specs; uses 2mm × 2mm UCSP package instead of TQFN-EP. | UCSP requires specialized assembly and board design; lower thermal mass but higher mechanical stress sensitivity. | Select MAX4693EBE+ only if PCB area is constrained beyond 3mm × 3mm and assembly process supports UCSP. |
| ADG774AACPZ-REEL7 | Quad SPDT, 4.5Ω max RON at +5V, but no dual-supply support and higher 25nA leakage at +85°C. | Optimized for single-supply +3V/+5V systems; lacks ±5V rail-to-rail capability for bipolar signal chains. | Choose ADG774A when only single-supply operation is needed and leakage tolerance >20nA is acceptable. |
Compared with MAX4693EBE+ and ADG774AACPZ-REEL7, the MAX4693ETE+ uniquely balances dual-supply flexibility, ultra-low leakage, and TQFN manufacturability - making it optimal for industrial portable instruments requiring ±5V signal integrity and RoHS-compliant surface-mount assembly.

FAQ
What supply configurations does the MAX4693ETE+ support?
The MAX4693ETE+ operates from either a single +2V to +11V supply (with V− tied to GND) or dual ±2V to ±5.5V supplies. At ±4.5V, it achieves 25Ω max on-resistance and 3Ω max channel matching. The MAX4693ETE+ datasheet specifies absolute maximum ratings up to ±5.5V, and the TQFN-EP package's exposed pad must be connected to V+ for optimal thermal performance.
Does the MAX4693ETE+ guarantee break-before-make timing?
Yes, the MAX4693ETE+ guarantees break-before-make operation with tBBM ≥ 2ns across -40°C to +85°C. This prevents momentary shorting between normally closed (NC) and normally open (NO) paths during switching transitions - a critical feature for glitch-free audio routing and sensor multiplexing. The MAX4693ETE+ truth table and timing diagrams in the official datasheet confirm this behavior under all valid supply and logic conditions.
What is the maximum leakage current specification for the MAX4693ETE+ at elevated temperature?
The MAX4693ETE+ specifies a maximum off-leakage current of ±20nA at +85°C for all switch terminals (X0/X1, Y0/Y1, Z0/Z1), as verified in the Electrical Characteristics tables for both single- and dual-supply conditions. This low leakage is maintained across the full operating range and directly supports precision applications such as thermocouple amplification and high-impedance sensor interfacing where DC accuracy is critical.
How does the MAX4693ETE+ handle logic-level translation for 1.8V microcontrollers?
The MAX4693ETE+ supports 1.8V logic compatibility when operated from a +3V supply, with VIH = +1.4V (min) and VIL = +0.4V (max). Its internal logic-level translators convert these low-voltage inputs into full-rail analog switch gate drives - eliminating need for external level shifters. This capability is explicitly validated in the MAX4693ETE+ datasheet's Electrical Characteristics section under "Single +3V Supply" conditions.
Can the MAX4693ETE+ be used in bipolar signal paths with ±5V supplies?
Yes, the MAX4693ETE+ is fully specified for dual ±5V operation, delivering 25Ω max on-resistance, ≤3.5Ω RON flatness, and -82dB off-isolation at 100kHz. Its analog signal range extends from V− to V+, supporting true rail-to-rail bipolar signals - making it suitable for professional audio interfaces, industrial data acquisition, and other ±5V signal chain applications where dynamic range and distortion performance matter.
