Product details
Overview
MAX396CAI+T from Maxim Integrated is a 16-channel, single-ended CMOS analog multiplexer designed for precision signal routing in low-voltage systems. It delivers ≤100Ω on-resistance (max), ≤6Ω channel-to-channel RON matching, and <1nA input off-leakage at +85°C, enabling high-fidelity data acquisition in battery-powered test equipment and industrial control interfaces.
For engineers reviewing the MAX396CAI+T datasheet, MAX396CAI+T pinout, MAX396CAI+T application, or MAX396CAI+T equivalent, key selection criteria include its ±2.7V to ±8V dual-supply operation, guaranteed 5pC max charge injection, break-before-make switching, and compatibility with legacy MAX306/DG406 footprints.
Technical Context
The MAX396CAI+T implements a silicon-gate CMOS switch architecture with integrated address decoding (A0–A3) and enable control (EN), supporting 1-of-16 channel selection. Its flat on-resistance profile (≤10Ω variation over ±3.5V signal range) and sub-250ns transition time ensure minimal gain/phase distortion in sampled-data systems.
It features bidirectional analog paths, TTL/CMOS-compatible digital inputs, and ESD protection >2000V (HBM). The device operates across 0°C to +70°C (indicated by 'C' grade) and is fabricated in a process optimized for low leakage and low charge injection-critical for high-resolution ADC front-ends and sample-and-hold circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 16 single-ended analog channels; enables consolidation of multiple signal sources onto one ADC or DAC path |
| On-resistance (RON) | ≤100Ω max at +25°C; ensures <0.1% gain error in 10kΩ source/load impedance applications |
| RON matching | ≤6Ω max between channels; preserves relative amplitude accuracy across multiplexed sensor inputs |
| Charge injection | ≤5pC max; limits voltage glitch on hold capacitors to <50mV with 100pF load |
| Off-leakage (INO(OFF)) | <1nA at +85°C; prevents >1LSB error in 16-bit, 1μF sample-and-hold circuits over temperature |
| Supply range | +2.7V to +16V single supply or ±2.7V to ±8V dual supply; supports rail-to-rail analog signal handling up to ±7.5V |
| Switching speed | tTRANS <250ns; allows ≥2MHz multiplexing rate in real-time control loops |
Pinout & Package
MAX396CAI+T is housed in a 28-pin SSOP (Shrink Small Outline Package) with 0.635mm pitch, 11.5mm × 5.3mm body size, and exposed pad not connected internally. Pin 1 is A3 (MSB address); pin 28 is V−; COM is pin 26; EN is pin 18; GND is pin 12; V+ is pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| COM (Pin 26) | Analog common output | Bidirectional signal path shared across all 16 channels; must be routed with controlled impedance for high-frequency integrity |
| NO1–NO16 (Pins 19–25, 4–11) | Analog input/output terminals | Individually selectable signal nodes; no internal series resistance-requires external ESD protection if exposed |
| A0–A3 (Pins 17, 16, 15, 14) | Binary address inputs | Selects active channel (0–15); latched on rising edge of EN; compatible with 3.3V/5V logic |
| EN (Pin 18) | Enable control | High = channel enabled; low = all switches open; supports synchronous power gating in multi-mux systems |
| V+ (Pin 1), V− (Pin 27) | Supply rails | Support split or single supply; V− must be tied to GND for single-supply use; voltage difference limited to ≤17V |
| GND (Pin 12) | Digital ground reference | Separate from analog return; requires star grounding near V+ and V− pins to minimize switching noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Precision on-resistance flatness | ≤10Ω variation over full ±3.5V analog range ensures consistent gain across signal swing in instrumentation amplifiers |
| Ultra-low charge injection | ≤5pC guarantees <100μV settling error on 100pF hold capacitors-critical for 16-bit+ SAR ADC drivers |
| Pin compatibility | Direct replacement for MAX306, DG406, and DG506A in existing layouts-no PCB revision required |
| Wide supply flexibility | Operates from +2.7V single supply or ±2.7V dual supply, enabling use in both portable and industrial power domains |
| High-temperature leakage control | <1nA NO off-leakage at +85°C maintains accuracy in uncooled industrial enclosures and avionics bays |
Applications

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), higher charge injection (15pC), and no guaranteed RON matching spec | Acceptable for lower-precision (<12-bit) data loggers where cost is prioritized over matching | Choose MAX306CPI+ only when budget constraints outweigh channel matching and low-leakage requirements |
| ADG1206BRUZ | 16-channel, but specified for ±15V supplies only; RON flatness 15Ω (vs. 10Ω), leakage 2.5nA at +85°C (vs. <1nA) | Suitable for high-voltage industrial I/O, not low-voltage battery systems requiring <3V operation | Select ADG1206BRUZ for ±15V rail applications; avoid for ≤±5V or high-temperature low-leakage use cases |
Compared with MAX306CPI+ and ADG1206BRUZ, the MAX396CAI+T uniquely combines 16-channel density, ≤6Ω RON matching, <1nA leakage at +85°C, and ±2.7V minimum supply-making it optimal for portable, high-accuracy, wide-temperature multiplexing where channel consistency is non-negotiable.

FAQ
What is the maximum supply voltage rating for MAX396CAI+T?
The MAX396CAI+T supports a maximum positive supply voltage (V+) of +17V and a minimum negative supply voltage (V−) of −17V, with an absolute maximum V+ to V− differential of 17V. Operation beyond these ratings risks permanent damage. For reliable long-term use, the recommended dual-supply range is ±2.7V to ±8V, and the single-supply range is +2.7V to +16V. These limits are defined in the Absolute Maximum Ratings table of the MAX396CAI+T datasheet.
Does MAX396CAI+T support single-supply operation below +3V?
The MAX396CAI+T is characterized and guaranteed for operation down to +2.7V; performance is not assured below this level. While functional behavior may persist at +1V, on-resistance increases dramatically (e.g., >650Ω at +3V), switching times degrade severely (up to 750ns), and leakage specifications are no longer valid. Therefore, MAX396CAI+T should not be used in production designs operating below +2.7V unless validated under actual system conditions and derated for reliability.
What is the pin-compatible replacement for MAX396CAI+T in existing PCB layouts?
The MAX396CAI+T is pin-compatible with the industry-standard MAX306, DG406, and DG506A multiplexers-same 28-pin SSOP footprint, identical pin functions (COM, NO1–NO16, A0–A3, EN, V+, V−, GND), and matching logic thresholds. This allows direct drop-in replacement without layout changes. However, due to its lower RON, tighter matching, and reduced charge injection, the MAX396CAI+T improves system accuracy and settling time over those legacy parts.
How does charge injection in MAX396CAI+T affect sample-and-hold performance?
With a guaranteed maximum charge injection of 5pC, the MAX396CAI+T introduces ≤50mV error on a typical 100pF hold capacitor-directly impacting acquisition accuracy in high-resolution ADC front-ends. This value is measured under standardized conditions (CL = 100pF, VNO = 0V) and remains stable across temperature. To minimize error, designers should pair the MAX396CAI+T with low-leakage hold capacitors and use break-before-make timing to prevent charge sharing between channels.
What temperature range is specified for the MAX396CAI+T variant?
The MAX396CAI+T is rated for operation from 0°C to +70°C, indicated by the 'C' suffix in the part number. This commercial-grade temperature range is validated per Maxim's production testing and applies to all electrical specifications in the datasheet unless otherwise noted. For extended-range applications (−40°C to +85°C), the MAX396EWI or MAX396EQI variants should be selected instead.
