Product details
Overview
The MAX4583LETE+ from Maxim Integrated is a low-voltage CMOS analog IC configured as three independent single-pole/double-throw (SPDT) switches, operating from +2V to +12V single supply, with rail-to-rail analog signal handling, 2nA off-leakage at +25°C, and 80Ω guaranteed on-resistance at +12V - used in precision audio routing and DSL modem front-end switching.
For engineers reviewing the MAX4583LETE+ datasheet, MAX4583LETE+ pinout, MAX4583LETE+ application, or MAX4583LETE+ equivalent, this page delivers verified pin functions, real-world crosstalk (-96dB), off-isolation (-90dB), on-resistance match (±4Ω), and QFN-EP package thermal performance for signal-path integrity validation.
Technical Context
The MAX4583LETE+ implements three fully independent SPDT analog switches with TTL/CMOS-compatible digital inputs (VIH = 2.0V, VIL = 0.8V at +12V supply), break-before-make timing (20ns max), and bidirectional signal paths. Each switch supports rail-to-rail analog voltages up to VCC with no ground reference required.
Its internal logic-level translators isolate digital control signals from analog paths, while reverse-biased ESD diodes between each analog pin and VCC/GND define leakage behavior. The exposed-pad TQFN package enables low thermal resistance and stable operation across -40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - supports battery-powered and industrial 3.3V/5V/12V systems without level-shifting. |
| On-Resistance (RON) | 80Ω max at +12V - ensures minimal insertion loss and voltage drop in signal chains up to 10Vpp. |
| RON Match | ±4Ω max between channels - critical for matched gain/attenuation in differential or multi-channel routing. |
| Off-Leakage Current | ±2nA at +25°C - preserves high-impedance sensor node accuracy and low-power standby integrity. |
| Off-Isolation | -90dB at 1MHz - prevents signal bleed between inactive SPDT paths in RF-adjacent or sensitive analog domains. |
| Crosstalk | -96dB at 1MHz (MAX4582L/MAX4583L) - maintains channel separation in multi-signal audio or data-acquisition systems. |
| Enable Turn-Off Time | 100ns max - enables fast channel switching in time-multiplexed sampling or dynamic reconfiguration. |
| Package | 16-pin TQFN-EP (4mm × 4mm) with exposed pad - provides low thermal resistance (1349mW PD at +70°C) and compact PCB footprint. |
Pinout & Package
16-pin Thin QFN with exposed pad (TQFN-EP), 4mm × 4mm body, 0.5mm pitch. Exposed pad must be soldered to VCC for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12–15 | Z0, Z1, Y0, Y1, X0, X1, X2, X3 | SPDT normally closed (NC) and normally open (NO) analog terminals - interchangeable input/output; no polarity constraint. |
| 3 | X | Common terminal for first SPDT switch - connects to either X0 (NC) or X1 (NO) based on address inputs. |
| 6 | Enable | Active-low digital enable - drives low or ties to GND for normal operation; high disables all switches. |
| 7, 8 | GND | Digital/analog ground reference - no analog signal ground path; analog signals float between VCC and GND. |
| 9 | C | MSB address input for channel selection - used only in MAX4583L's 3-bit decode (CBA) to select Z-path state. |
| 10, 11 | B, A | Address bits for SPDT control - jointly determine which NO/NC pair connects to common (X/Y/Z). |
| 14, 16 | VCC | Positive supply for analog switches and logic - bypass with 0.1µF capacitor; sets analog signal range limit. |
| EP (bottom) | Exposed Pad | Internally connected to VCC - must be externally soldered to VCC plane for thermal dissipation and noise reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full VCC-to-GND swing without clipping - enables direct interfacing with op-amps, ADCs, and DACs. |
| Guaranteed 4Ω RON match | Ensures consistent gain/phase response across SPDT paths - essential for balanced audio or instrumentation multiplexing. |
| Low 2nA off-leakage at +25°C | Maintains signal integrity in high-Z sensor interfaces and battery-critical sleep modes. |
| TTL/CMOS logic compatibility | 0.8V–2.0V thresholds at +12V supply - eliminates need for external level shifters in mixed-voltage systems. |
| Pin compatibility with 74HC4053/MAX4053 | Drop-in replacement for legacy designs - reduces redesign risk and accelerates qualification in existing layouts. |
Applications
| Audio Signal Routing | DSL Modem Front-End |
|---|---|
Use Scenario: Switching between multiple microphone inputs or speaker outputs in portable audio devices with dynamic channel selection. IC Role / Device Role / Timing Role: Three independent SPDT switches route analog audio paths under microcontroller GPIO control with sub-200ns switching. Use Value: Low THD (0.02%) and -96dB crosstalk preserve stereo separation and SNR in consumer-grade audio subsystems. | Use Scenario: Selecting between line drivers, filters, and hybrid circuits in ADSL/VDSL transceivers during mode transitions. IC Role / Device Role / Timing Role: Analog switch matrix managing signal path configuration in DSL PHY layer with rail-to-rail 0–12V support. Use Value: 80Ω RON and ±4Ω matching ensure flat frequency response and minimal echo distortion across 1–30MHz band. |
| Data-Acquisition Multiplexing | Communications Channel Isolation |
Use Scenario: Scanning multiple sensor outputs (thermocouples, RTDs, strain gauges) into a single ADC input with minimal offset drift. IC Role / Device Role / Timing Role: Precision SPDT switch providing low-leakage (<2nA), low-charge-injection (0.5pC) signal gating before ADC sampling. Use Value: 2nA on/off leakage and 0.5pC charge injection prevent baseline shift and settling errors in 16-bit+ measurement systems. | Use Scenario: Isolating backup communication lines (RS-485, CAN, or analog telemetry) from primary paths during fault conditions.

Use Value: -90dB off-isolation blocks coupling between active/inactive channels - critical for safety-critical telecom and industrial control. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4053ACPE+ | Same 16-pin DIP package; 100Ω RON max at +15V; higher 10nA leakage at +25°C. | Legacy through-hole designs; less suitable for space-constrained or low-leakage applications. | Select when board uses DIP sockets or requires higher voltage margin (+15V). |
| ADG1414BRUZ | 16-pin TSSOP; 1.5Ω RON typical at +15V; ±100pC charge injection; -100dB off-isolation. | High-precision instrumentation requiring ultra-low RON and isolation - not pin-compatible. | Select for metrology-grade systems where RON match and THD outweigh footprint constraints. |
Compared with MAX4583LETE+, MAX4053ACPE+ offers through-hole compatibility but trades leakage and RON for legacy support, while ADG1414BRUZ delivers superior analog specs at the cost of non-drop-in layout changes and higher cost.

FAQ
What is the maximum supply voltage rating for the MAX4583LETE+?
The MAX4583LETE+ has an absolute maximum supply voltage of +13V, with recommended continuous operation from +2V to +12V. Operation beyond +12.6V risks exceeding absolute maximum ratings and may cause permanent damage. The device is production-tested over -40°C to +85°C at +12V nominal supply, and all guaranteed parameters assume VCC ≤ +12.6V.
Does the MAX4583LETE+ support bidirectional analog signal flow?
Yes, the MAX4583LETE+ supports fully bidirectional analog signal flow - any pin labeled X, Y, or Z (common) and X0/X1, Y0/Y1, Z0/Z1 (NO/NC) can serve as input or output. This is explicitly confirmed in the datasheet: "Input and output pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well in both directions." No internal directionality limits apply.
How is the exposed pad on the MAX4583LETE+ package connected?
The exposed pad (EP) on the MAX4583LETE+ TQFN package is internally connected to VCC and must be externally soldered to the VCC plane on the PCB. This connection is mandatory for thermal dissipation (enabling 1349mW power dissipation at +70°C) and optimal noise immunity. Leaving the pad floating or grounding it violates the datasheet requirement and degrades performance and reliability.
What is the guaranteed on-resistance match between SPDT channels in the MAX4583LETE+?
The MAX4583LETE+ guarantees a maximum on-resistance match (ΔRON) of 4Ω between its three SPDT channels at +25°C, defined as RON(MAX) – RON(MIN). This specification holds across the full -40°C to +85°C temperature range with a worst-case match of 5Ω. The tight match ensures consistent gain, phase, and settling behavior when routing parallel or differential signals.
Is the MAX4583LETE+ pin-compatible with industry-standard alternatives?
Yes, the MAX4583LETE+ is explicitly pin-compatible with the 74HC4053 and MAX4053 families in the same 16-pin SO/QSOP/TQFN footprints. Pin functions (X/Y/Z commons, X0/X1 etc., A/B/C address, ENABLE, VCC, GND) align directly - enabling drop-in replacement without PCB modification. This compatibility is stated in the datasheet's "Pin Nomenclature" section and validated across all package variants including TQFN-EP.
