Product details
Overview
MAX396CAI from Maxim Integrated is a precision 16-channel single-ended CMOS analog multiplexer designed for low-voltage signal routing in data acquisition and instrumentation systems. It delivers ≤100Ω on-resistance (max), ≤6Ω channel-to-channel RON matching, and <1nA input off-leakage at +85°C, operating from +2.7V to +16V single supply or ±2.7V to ±8V dual supplies.
For engineers reviewing the MAX396CAI datasheet, MAX396CAI pinout, MAX396CAI application, or MAX396CAI equivalent, this device is selected for high-accuracy analog switching where low charge injection (≤5pC), flat on-resistance over signal range (≤10Ω variation), and TTL/CMOS-compatible logic inputs are required in industrial, test equipment, and battery-powered designs.
Technical Context
The MAX396CAI implements a silicon-gate CMOS architecture with integrated address decoding (4-bit A3–A0) and enable-controlled channel selection. Its switch array uses matched transistor pairs to guarantee tight RON matching and flatness across the full analog signal range (VCOM/VNO = V− to V+).
It features break-before-make switching (tOPEN ≤70ns), fast transition time (tTRANS ≤250ns), and electrostatic discharge protection >2000V per Method 3015.7 - all while maintaining <10μW quiescent power consumption and compatibility with industry-standard pinouts including MAX306, DG406, and DG506A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 16-channel single-ended analog multiplexer with COM output and NO1–NO16 inputs |
| On-resistance (RON) | ≤100Ω max at +25°C (V+ = +5V, V− = −5V); ensures minimal signal attenuation and gain error in precision measurement paths |
| RON matching | ≤6Ω max between channels; critical for multi-channel calibration and ratiometric measurements |
| Charge injection | ≤5pC max; limits voltage glitch on sampled nodes in sample-and-hold and ADC front-end applications |
| Off-leakage current | <1nA at +85°C (input), <2.5nA (output); preserves accuracy in high-impedance sensor interfaces |
| Supply range | +2.7V to +16V single supply or ±2.7V to ±8V dual supply; supports wide-range battery and rail-flexible industrial systems |
| Logic compatibility | TTL/CMOS inputs (VAH ≥2.4V, VAL ≤0.8V); enables direct interfacing with microcontrollers and FPGAs without level-shifting |
Pinout & Package
MAX396CAI is housed in a 28-pin SSOP (Shrink Small Outline Package) with 0.635mm pitch, optimized for high-density PCB layouts while maintaining thermal and electrical performance comparable to wider SO and PLCC variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| COM | Analog common output | Bidirectional signal path shared across all 16 channels; connects to ADC input, amplifier summing node, or DAC output |
| NO1–NO16 | Analog inputs | 16 independent bidirectional analog terminals; each routed to COM when selected by A3–A0 and EN |
| A0–A3 | Binary address inputs | 4-bit code selects one of 16 channels (0000 = NO1, 1111 = NO16); latched on rising edge of EN |
| EN | Enable control input | Active-high logic input enabling/disabling all switches; allows global channel gating and power sequencing control |
| V+, V− | Supply rails | Supports single-ended (+2.7V to +16V) or split-rail (±2.7V to ±8V) operation; defines analog signal swing boundaries |
| GND | Logic ground reference | Reference for digital inputs (A0–A3, EN); isolated from analog signal path but tied to substrate via V+ |
| N.C. | No internal connection | Pins 2, 3, 13 are unconnected; must be left floating or grounded per layout best practices |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility | Fully pin-compatible with MAX306, DG406, and DG506A - enables drop-in replacement without PCB redesign |
| RON flatness | ≤10Ω variation over full signal range (V− to V+); maintains consistent gain and linearity across input voltage extremes |
| Low power operation | <10μW typical supply current; extends battery life in portable instrumentation and remote sensors |
| ESD robustness | >2000V HBM per Method 3015.7; reduces field failure risk in handling and system-level ESD events |
| Temperature stability | RON drift ≤125Ω max over −40°C to +85°C; supports reliable operation in industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX306CPI | Same 16-channel function, but higher RON (120Ω typ), no guaranteed RON matching spec, and no charge injection limit stated | Suitable for non-precision applications where cost is prioritized over matching and glitch performance | Select MAX306CPI only if RON matching >6Ω and charge injection >5pC are acceptable in the target design |
| DG406DN | 16-channel mux with 100Ω RON, but higher off-leakage (5nA at +85°C) and no specified charge injection or RON flatness | Applicable in general-purpose switching where leakage-induced offset drift is mitigated by system calibration | Choose DG406DN when legacy footprint compatibility is needed and leakage sensitivity is low |
Compared with MAX396CAI, MAX306CPI offers lower cost but sacrifices guaranteed RON matching and charge injection control, while DG406DN provides broader vendor availability but lacks leakage and flatness guarantees critical for high-accuracy data acquisition.

FAQ
What is the maximum operating temperature range for the MAX396CAI?
The MAX396CAI is rated for operation from 0°C to +70°C, as indicated by the 'C' suffix in its part number. This commercial-grade temperature range is validated per the device's Absolute Maximum Ratings and Electrical Characteristics tables, and applies specifically to the MAX396CAI variant in 28-pin SSOP packaging.
Does the MAX396CAI support single-supply operation?
Yes, the MAX396CAI supports single-supply operation from +2.7V to +16V. When using a single supply, V− must be connected to GND. Performance parameters-including on-resistance, leakage, and switching speed-are fully specified across this range, with datasheet test conditions explicitly covering +3V and +5V single-supply configurations.
Is the MAX396CAI pin-compatible with the MAX306 series?
Yes, the MAX396CAI is explicitly pin-compatible with the MAX306/MAX307 family, as confirmed in both the Benefits and Features section and the Ordering Information table of the official datasheet. This compatibility extends to pin assignments, package outlines, and functional behavior-enabling direct substitution in existing MAX306-based designs.
What is the guaranteed on-resistance matching specification for the MAX396CAI?
The MAX396CAI guarantees ≤6Ω maximum on-resistance matching (ΔRON) between any two channels at +25°C, and ≤8Ω over the full operating temperature range (0°C to +70°C). This parameter is 100% tested and specified in the Electrical Characteristics table under "On-Resistance Matching Between Channels".
How does the MAX396CAI handle charge injection during switching?
The MAX396CAI guarantees ≤5pC maximum charge injection (QCTE) at +25°C, measured with CL = 100pF and VNO = 0V. This low value minimizes voltage glitches on high-impedance nodes-such as sample-and-hold capacitors-and is validated across temperature and supply conditions per the datasheet's Typical Operating Characteristics and Electrical Characteristics sections.
