Product details
Overview
The MAX4623CPE+ from Maxim Integrated is a precision dual-pole/single-throw (DPST) analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in test equipment and communication systems. It delivers 5Ω maximum on-resistance, 0.5Ω max channel-to-channel RON match, <5nA off-leakage at +85°C, and sub-250ns switching times under ±15V dual-supply operation.
For engineers reviewing the MAX4623CPE+ datasheet, MAX4623CPE+ pinout, MAX4623CPE+ application, or MAX4623CPE+ equivalent, key selection criteria include guaranteed break-before-make timing (in related MAX4622), low charge injection (45pC), high off-isolation (–62dB at 1MHz), and compatibility with +4.5V to +36V single or ±4.5V to ±18V bipolar supplies.
Technical Context
The MAX4623CPE+ implements two independent SPST switches in a monolithic CMOS process, each with matched on-resistance across its full analog signal range (VCOM = V− to V+). Its logic inputs accept TTL/CMOS levels and are referenced to VL (logic supply), decoupled from analog supply rails.
It supports rail-to-rail analog signal handling without degradation in RON flatness (∆RON ≤ 0.5Ω), and features internal protection diodes that clamp signals exceeding V+ or V−, enabling robust operation in mixed-signal environments where overvoltage transients may occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 5Ω max - ensures minimal signal attenuation and voltage drop in precision signal paths |
| RON Match | 0.5Ω max - enables accurate differential or ratiometric measurements across channels |
| Off-Leakage Current | <5nA at +85°C - preserves signal integrity in high-impedance sensor or sample-hold circuits |
| Turn-On/Off Time | <250ns / <200ns - supports high-speed multiplexing in automated test and data acquisition |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±18V (dual) - accommodates industrial and telecom power architectures |
| Charge Injection | 45pC - limits voltage glitch on sampled nodes in ADC front-ends |
| Off-Isolation | –62dB at 1MHz - suppresses crosstalk between active and inactive signal paths |
Pinout & Package
MAX4623CPE+ uses a 16-pin plastic DIP package (0.3-inch width) with through-hole mounting. Pin functions are validated per Maxim's official pin configuration diagram for MAX4623.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | Digital Logic Input (IN1, IN2) | Active-high control lines; CMOS/TTL compatible, referenced to VL |
| 2, 7 | Switch Common Terminal (COM1, COM2) | Analog current path input/output; handles rail-to-rail signals from V− to V+ |
| 4, 5, 9, 16 | Switch Normally Open Terminal (NO1–NO4) | Open-circuit when unasserted; connects to COMx only when corresponding INx = high |
| 6, 11, 14 | No Connect (N.C.) | Not bonded internally; must remain unconnected in PCB layout |
| 12 | Positive Supply (V+) | Primary analog supply rail; supports up to +36V in single-supply mode |
| 3, 13 | Negative Supply (V−) / Logic Supply (VL) | V− sets lower analog rail (down to –18V); VL powers logic interface (typically +5V) |
| 15 | Ground (GND) | Logic reference and substrate tie; separate from analog return paths in mixed-signal designs |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail® Analog Signal Handling | Supports full-swing signals from V− to V+ without clipping or distortion, critical for audio and sensor interfaces |
| Guaranteed RON Matching | ≤0.5Ω mismatch between channels ensures consistent gain/attenuation in dual-path systems |
| TTL/CMOS-Logic Compatibility | Accepts standard logic thresholds (0.8V/2.4V) independent of analog supply voltages |
| Low Charge Injection (45pC) | Minimizes sampling error in switched-capacitor circuits and precision ADC drivers |
| Pin-Compatible with DG405 | Direct replacement for legacy DG405 DPST switches without PCB redesign |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4623CSE+ | Narrow SOIC-16 package (surface-mount); identical electrical specs and pinout | Suitable for space-constrained PCBs requiring reflow assembly instead of through-hole | Select MAX4623CSE+ when board real estate or automated assembly drives package choice |
| ADG408BRZ | 8-channel single-pole analog multiplexer; 45Ω typical RON; no guaranteed RON match spec | Better suited for multi-input selection rather than dual independent SPST control | Choose ADG408BRZ only when channel count outweighs matching and low-RON requirements |
Compared with MAX4623CPE+, the MAX4623CSE+ offers identical functionality in a surface-mount package, while the ADG408BRZ trades channel independence and precision matching for higher integration-making it unsuitable as a direct functional substitute in dual-SPST applications demanding tight RON tracking.

FAQ
What is the maximum analog signal voltage range supported by the MAX4623CPE+?
The MAX4623CPE+ supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of –44V to +44V across V+ and V−. Under standard operation, it handles ±15V dual supplies or +12V single supply, enabling full-swing signal routing without clipping or distortion in the MAX4623CPE+.
Does the MAX4623CPE+ require external pull-up or pull-down resistors on its logic inputs?
No, the MAX4623CPE+ logic inputs are TTL/CMOS-compatible and do not require external biasing. They accept VINL ≤ 0.8V and VINH ≥ 2.4V with input currents under ±0.5µA across temperature, ensuring reliable switching without added components in the MAX4623CPE+ interface.
Can the MAX4623CPE+ operate with V+ = +12V and V− = GND (single-supply mode)?
Yes, the MAX4623CPE+ operates with +4.5V to +36V single supply. With V+ = +12V and V− = GND, it maintains 5Ω max RON, <1nA off-leakage at +25°C, and 200ns turn-off time-fully specified per its single-supply electrical characteristics table in the MAX4623CPE+ datasheet.
What is the thermal performance of the MAX4623CPE+ over its operating temperature range?
The MAX4623CPE+ is rated for 0°C to +70°C (C-grade). On-resistance varies by ≤±0.5Ω across this range at ±15V supplies, and off-leakage remains <5nA at +85°C (extrapolated per test correlation). Power dissipation is limited to 842mW at +70°C in the plastic DIP package for the MAX4623CPE+.
Is the MAX4623CPE+ pin-compatible with the DG405 analog switch?
Yes, the MAX4623CPE+ is explicitly documented as a pin-compatible replacement for the DG405. Both use 16-pin DIP packages with identical pin assignments for IN1/IN2, COM1/COM2, NO1–NO4, V+, V−, VL, and GND-enabling drop-in upgrades without layout changes for the MAX4623CPE+.
