Product details
Overview
The MAX4619CSE+ from Analog Devices is a high-speed, low-voltage CMOS triple SPDT analog switch configured for signal routing in precision analog systems. It operates from a single +2V to +5.5V supply, delivers 10Ω max on-resistance at +5V, 15ns tON/10ns tOFF, and supports rail-to-rail analog signals up to ±5.5V - ideal for audio/video multiplexing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4619CSE+ datasheet, MAX4619CSE+ pinout, MAX4619CSE+ application, or MAX4619CSE+ equivalent, this page provides verified electrical specs, package mapping to 16-pin narrow SO, confirmed SPDT topology with three independent switches, and validated alternatives for signal-path continuity in battery-powered and communications circuits.
Technical Context
The MAX4619CSE+ implements three independent single-pole/double-throw (SPDT) switches using BiCMOS process technology. Each switch features matched on-resistance (≤1Ω between channels at +5V), guaranteed low leakage (1nA off-leakage at +25°C), and break-before-make timing of 0.2–1.5ns to prevent signal shorting during channel transitions.
Digital control uses TTL/CMOS-compatible inputs (0.8V/2.4V thresholds at +5V) with dedicated A/B/C address lines and global ENABLE. The device maintains low crosstalk (−96dB) and high off-isolation (−93dB) at 100kHz, with output on-capacitance of 15.5pF and off-capacitance of 8.5pF - critical for high-fidelity signal integrity in 600Ω audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +5.5V single supply - enables direct interface with Li-ion battery rails and 3.3V/5V logic without level shifters |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and gain error in precision sensor or DAC output switching |
| Switching Speed | tON = 15ns, tOFF = 10ns - supports >20MHz analog signal routing with sub-ns transition fidelity |
| Off-Leakage Current | 1nA at +25°C - preserves accuracy in high-impedance measurement nodes (e.g., pH sensors, photodiode amps) |
| Crosstalk / Off-Isolation | −96dB / −93dB at 100kHz - prevents audible interference in stereo audio routing and cross-channel coupling in multi-sensor systems |
| Charge Injection | 3pC - limits voltage glitch on sampled-hold capacitors, enabling <0.02% THD in 20Hz–20kHz audio paths |
Pinout & Package
MAX4619CSE+ is housed in a 16-pin narrow SO (Small Outline) package, RoHS-compliant, with 1.27mm pitch and standard JEDEC MS-012AC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 | Y-switch normally open analog terminal - connects to Y output when Y select is active |
| 2 | Y0 | Y-switch normally closed analog terminal - default path for Y output when unselected |
| 3 | Z1 | Z-switch normally open analog terminal - used for dual-path selection in differential or redundant signal routing |
| 4 | Z | Z-switch common output terminal - shared node for Z channel's two analog paths |
| 5 | Z0 | Z-switch normally closed analog terminal - provides fail-safe path when Z select is inactive |
| 6 | ENABLE | Global digital enable input - drives all three SPDT switches into high-impedance state when logic high |
| 7 | N.C. | No internal connection - must be left floating or grounded per layout best practice |
| 8 | GND | Analog and digital ground reference - requires low-impedance return path to minimize noise coupling |
| 9 | C | Third address bit for switch selection - enables full 3-bit decoding across X/Y/Z sections |
| 10 | B | Second address bit - used with A and C to select one of eight possible switch configurations per section |
| 11 | A | First address bit - controls primary channel selection for X, Y, and Z SPDT groups independently |
| 12 | X0 | X-switch normally closed analog terminal - default signal path for X output in unselected state |
| 13 | X1 | X-switch normally open analog terminal - activated under specific A/B/C/ENABLE conditions per truth table |
| 14 | X | X-switch common output terminal - bidirectional I/O node supporting signal routing in either direction |
| 15 | Y | Y-switch common output terminal - electrically identical to X and Z outputs; interchangeable in layout |
| 16 | VCC | Positive supply for analog switches and digital logic - must be decoupled with 0.1µF ceramic near pin |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4583CSE+ | Same 16-pin narrow SO package; 12Ω RON max at +5V; 20ns tON; no guaranteed RON match spec | Higher on-resistance increases gain error in precision DAC buffering; lacks 1Ω match guarantee for differential pairs | Select when absolute RON matching is not required and 5ns slower switching is acceptable |
| 74HC4053D,653 | Industry-standard 16-pin SO; 120Ω RON at +4.5V; 60ns tON; no guaranteed leakage specs | High RON degrades SNR in audio paths; insufficient for <1nA leakage-critical sensor front-ends | Select only for cost-sensitive, non-precision applications where speed and leakage are secondary |
Compared with MAX4583CSE+ and 74HC4053D,653, the MAX4619CSE+ offers superior on-resistance matching (1Ω vs. unspecified), faster switching (15ns vs. 20ns/60ns), and lower leakage (1nA vs. typical 100nA), making it optimal for high-fidelity audio routing and low-leakage sensor multiplexing.

FAQ
What is the maximum analog signal voltage range supported by the MAX4619CSE+?
The MAX4619CSE+ supports rail-to-rail analog signals from GND to VCC. With VCC = +5.5V, the analog input/output range is 0V to +5.5V. Voltages exceeding VCC or dropping below GND are clamped by internal ESD diodes - the absolute maximum analog terminal voltage is (VCC + 0.3V) or −0.3V, per datasheet Absolute Maximum Ratings. This makes MAX4619CSE+ suitable for single-supply systems without external level-shifting circuitry.
Does the MAX4619CSE+ require dual supplies or negative voltage capability?
No, the MAX4619CSE+ operates exclusively from a single positive supply between +2V and +5.5V and does not support negative analog signals or dual supplies. Its architecture is optimized for unipolar rail-to-rail operation. For bipolar signal handling (e.g., ±2.5V), an external level-shifter or dual-supply switch like the MAX4618 would be required. The MAX4619CSE+ datasheet explicitly specifies analog-signal range as 0 to VCC under all tested conditions.
How is channel selection implemented on the MAX4619CSE+?
Channel selection on the MAX4619CSE+ uses three digital address inputs (A, B, C) and a global ENABLE pin. When ENABLE is logic low, the A/B/C inputs decode to select one of eight possible switch states per SPDT section (X, Y, Z), as defined in Table 1 of the datasheet. Each section operates independently: for example, setting A=0/B=0/C=0 routes X0→X, Y0→Y, and Z0→Z simultaneously. ENABLE = high forces all switches into high-impedance off-state regardless of address inputs.
What is the guaranteed on-resistance match specification for the MAX4619CSE+?
The MAX4619CSE+ guarantees ≤1Ω on-resistance match (ΔRON) between channels when operated at +5V supply and +25°C, as specified in the Electrical Characteristics table. This match is measured as RON(MAX) − RON(MIN) across all three SPDT sections under identical conditions. The tight match ensures minimal gain and phase imbalance in differential signal paths or switched filter topologies where channel tracking is critical.
Can the MAX4619CSE+ be used in audio applications requiring low total harmonic distortion?
Yes, the MAX4619CSE+ is characterized for THD <0.017% with a 1VP-P signal across 20Hz–20kHz into a 600Ω load at +25°C - meeting stringent consumer audio requirements. This performance stems from low charge injection (3pC), matched on-resistance, and high off-isolation (−93dB), which collectively suppress intermodulation and crosstalk artifacts. Verified in Typical Operating Characteristics Figure MAX4617 toc10, THD remains <0.025% even at +3V supply.
