Product details
Overview
MAX352CPE+ from Maxim Integrated is a precision quad single-pole single-throw (SPST) analog switch with four normally open (NO) channels, designed for high-fidelity signal routing in precision instrumentation and military-grade systems. It delivers ≤35Ω on-resistance, <2Ω channel-to-channel matching, <10pC charge injection, <6nA off-leakage at +85°C, and rail-to-rail analog signal handling up to ±20V supplies - enabling use in sample-and-hold circuits and battery-operated guidance systems.
For engineers reviewing the MAX352CPE+ datasheet, MAX352CPE+ pinout, MAX352CPE+ application, or MAX352CPE+ equivalent, key selection criteria include guaranteed on-resistance flatness (∆3Ω max), ESD tolerance >2000V, dual-supply operation (±4.5V to ±20V), TTL/CMOS logic compatibility, and 16-pin plastic DIP packaging for through-hole prototyping and ruggedized deployment.
Technical Context
The MAX352CPE+ implements four independent NO SPST switches fabricated in Maxim's 44V silicon-gate process, supporting both bipolar (±4.5V to ±20V) and single-supply (+10V to +30V) operation while maintaining CMOS-input compatibility and low power consumption (35µW). Its architecture guarantees matched on-resistance (<2Ω) and flat on-resistance over full analog range (∆3Ω max), critical for multi-channel signal integrity.
It features rail-to-rail analog signal capability, low charge injection (≤10pC), and tight leakage control (<250pA at +25°C, <6nA at +85°C), making it suitable for high-precision sampling where signal settling and crosstalk must be minimized - especially in military radios and heads-up displays where temperature stability and ESD robustness are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance | ≤35Ω max - ensures minimal signal attenuation and voltage drop across switched paths at full analog range. |
| On Resistance Match | <2Ω between channels - enables precise gain/offset matching in multi-channel data acquisition systems. |
| Charge Injection | ≤10pC - reduces sampling error and pedestal shift in precision sample-and-hold and ADC front-end applications. |
| Off-Leakage Current | <6nA at +85°C - maintains signal integrity in high-impedance sensor interfaces and long-hold-time circuits. |
| Supply Range | ±4.5V to ±20V bipolar or +10V to +30V single supply - supports rail-to-rail analog signals without level-shifting circuitry. |
| ESD Rating | >2000V per Method 3015.7 - provides robust handling in manufacturing and field-deployed military/aerospace environments. |
| Switching Speed | tON <175ns, tOFF <145ns - enables fast multiplexing in real-time test equipment and communications systems. |
Pinout & Package
MAX352CPE+ uses a 16-pin plastic DIP package (0.300" wide), rated for 0°C to +70°C operation, with through-hole mounting and industry-standard footprint compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 15, 14, 7, 6) | Logic Control Input | CMOS/TTL-compatible digital inputs controlling respective NO switch states (logic high = ON). |
| COM1–COM4 (Pins 2, 15, 10, 7) | Analog Switch Common Terminal | Common connection point for each SPST channel; carries routed analog signal when switch is closed. |
| NO1–NO4 (Pins 1, 16, 11, 8) | Analog Switch Normally Open Terminal | Open-circuit terminal that connects to COM only when corresponding IN is high - defines NO topology. |
| V+ (Pin 13) | Positive Supply Voltage | Bias supply input (up to +30V); substrate tied to V+, requiring proper sequencing during power-up. |
| V− (Pin 4) | Negative Supply Voltage | Bias supply input (down to −20V); must be sequenced after V+ to prevent latch-up or overstress. |
| VL (Pin 12) | Logic Supply Voltage | Separate 5V logic rail for TTL compatibility; can be tied to V+ for CMOS-level inputs. |
| GND (Pin 5) | Ground Reference | Signal reference for logic inputs and internal biasing; distinct from analog ground in mixed-signal layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals from V− to V+ (±20V max), eliminating need for external clamping or level-shifting in wide-dynamic-range systems. |
| Guaranteed on-resistance flatness | ∆RON ≤3Ω over full analog range - preserves linearity and minimizes harmonic distortion in audio and instrumentation paths. |
| Low charge injection | ≤10pC - critical for accurate DC-coupled sampling in precision data converters and hold capacitors ≥1nF. |
| High ESD tolerance | >2000V per Method 3015.7 - ensures reliability during board assembly and field maintenance without added protection circuitry. |
| Split- and single-supply flexibility | Operates from ±4.5V to ±20V or +10V to +30V - simplifies power architecture in mixed-voltage systems like PBX and test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG442BRZ | Higher on-resistance (75Ω typ), wider temp range (−40°C to +125°C), SOIC-16 package only. | Better suited for industrial PLC I/O modules needing extended temperature operation but less ideal for low-distortion sampling. | Select ADG442BRZ when ambient temperature exceeds +85°C and layout allows surface-mount assembly. |
| TS5A3157DCKR | Single-channel, lower voltage rating (5.5V max), smaller SC70-6 package, higher leakage (>100nA at +85°C). | Targeted at low-voltage consumer portables; lacks quad integration and rail-to-rail capability of MAX352CPE+. | Choose TS5A3157DCKR only for space-constrained, single-path, 3.3V/5V designs where precision and leakage are secondary. |
Compared with ADG442BRZ and TS5A3157DCKR, the MAX352CPE+ uniquely combines quad NO topology, ≤35Ω on-resistance, <10pC charge injection, and ±20V rail-to-rail support in a through-hole DIP package - making it irreplaceable for legacy military, aerospace, and bench-test systems demanding proven reliability and analog fidelity.

FAQ
What is the maximum analog signal voltage range supported by the MAX352CPE+?
The MAX352CPE+ supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of ±44V on V+ relative to V−. In standard operation, it handles ±20V bipolar supplies or +30V single supply, enabling full-range signal switching without external clamping diodes or level shifters - a key advantage in high-dynamic-range test equipment and military radios where signal integrity is non-negotiable.
Does the MAX352CPE+ require separate logic and analog supplies?
Yes - the MAX352CPE+ has a dedicated VL pin (Pin 12) for logic supply, typically +5V for TTL compatibility or tied to V+ for CMOS levels. This separation prevents digital noise coupling into analog paths and ensures clean switching thresholds. The analog supplies (V+ and V−) power the switch core and must be sequenced correctly: V+ first, then VL, then V− and logic inputs - a requirement explicitly documented in the MAX352CPE+ datasheet to avoid latch-up or overstress.
How does the MAX352CPE+ achieve <2Ω on-resistance matching between channels?
The MAX352CPE+ achieves <2Ω on-resistance matching via monolithic fabrication in Maxim's 44V silicon-gate process, with laser-trimmed geometry and matched transistor sizing across all four channels. This matching is guaranteed over temperature and signal voltage - not just at room temperature - and is validated per datasheet test conditions using bipolar supplies (±15V), ensuring consistent gain scaling in multi-channel data acquisition systems where channel-to-channel uniformity directly impacts measurement accuracy.
Can the MAX352CPE+ be used in single-supply +12V applications?
Yes - the MAX352CPE+ operates from +10V to +30V single supply. When using +12V, connect V− to GND, tie VL to +5V (for TTL) or +12V (for CMOS), and ensure analog signals stay within 0V to +12V. Note that on-resistance increases slightly versus ±15V operation (e.g., ~45Ω max vs. 35Ω), and switching times lengthen - but full functionality, including <10pC charge injection and <6nA leakage, remains guaranteed per the MAX352CPE+ electrical characteristics table for single-supply conditions.
What is the significance of the "CPE" suffix in MAX352CPE+?
The "CPE" suffix in MAX352CPE+ denotes a commercial-grade (0°C to +70°C) device in a 16-pin plastic DIP package with lead-free (Pb-free) finish and RoHS-compliant construction. The "+" indicates Maxim's enhanced quality grade - including 100% wafer sort, burn-in, and extended reliability testing - distinguishing it from standard CPE variants and confirming suitability for high-reliability prototyping and low-volume production in industrial and defense applications where traceability and consistency are required.
