Product details
Overview
The MAX396CPI+ from Maxim Integrated is a precision 16-channel single-ended CMOS analog multiplexer designed for low-voltage signal routing in data acquisition and test systems. It delivers ≤100Ω on-resistance (max), ≤6Ω channel-to-channel RON matching, and <1nA input off-leakage at +85°C, enabling high-accuracy sampling in battery-powered and industrial instrumentation.
For engineers reviewing the MAX396CPI+ datasheet, MAX396CPI+ pinout, MAX396CPI+ application, or MAX396CPI+ equivalent, this page provides verified electrical specs, package mapping to 28-pin PDIP, real-world switching performance under ±5V and +5V supplies, and validated alternatives for precision analog mux replacement.
Technical Context
The MAX396CPI+ uses Maxim's low-voltage silicon-gate CMOS process to achieve flat on-resistance over its full analog signal range (±5V dual supply or 0–5V single supply), with guaranteed RON flatness ≤10Ω and charge injection ≤5pC. Its break-before-make architecture prevents signal shorting during channel transitions.
It supports TTL/CMOS-compatible digital control (logic thresholds: VIL ≤ 0.8V, VIH ≥ 2.4V) and operates across supply configurations: ±2.7V to ±8V dual or +2.7V to +16V single, with supply current <1µA per rail at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 16 single-ended analog inputs, 1 common output (COM) |
| On-resistance (RON) | ≤100Ω max at +25°C (±5V supplies); ensures minimal signal attenuation and gain error in precision measurement paths |
| RON matching | ≤6Ω max between channels; critical for multichannel ratiometric measurements and calibration stability |
| Charge injection | ≤5pC max; limits voltage glitch on sample-and-hold capacitors, preserving ADC accuracy |
| Input off-leakage | <1nA at +85°C; enables high-impedance sensor interfacing without significant offset drift |
| Supply range | +2.7V to +16V single or ±2.7V to ±8V dual; supports operation from Li-ion battery (3.0V) up to industrial rails |
| Transition time | <250ns max; allows multiplexing at >1MHz effective sampling rates in fast data acquisition |
Pinout & Package
MAX396CPI+ is housed in a 28-pin plastic DIP (dual in-line package) with 0.600" wide body and 0.100" lead pitch. Pin 1 is marked by a notch or dot; substrate tied to V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 27, 28 | V+, V−, COM | Positive supply input (pin 1), negative supply input (pin 27), analog common output (pin 28) |
| 2–3, 13 | N.C. | No internal connection - must be left unconnected; no pull-up/down or bypass required |
| 4–11, 19–26 | NO16–NO9, NO1–NO8 | 16 bidirectional analog signal inputs; fully interchangeable with COM for signal routing flexibility |
| 12 | GND | Digital logic ground reference; separate from analog return paths to minimize noise coupling |
| 14–17 | A3–A0 | 4-bit binary address inputs selecting one of 16 channels; CMOS/TTL compatible (0.8V/2.4V thresholds) |
| 18 | EN | Active-high enable; disables all switches when low, reducing leakage and power in standby mode |
Key Features
| Feature | Design Value |
|---|---|
| Precision RON matching | ≤6Ω max channel-to-channel variation ensures consistent gain scaling across all 16 channels |
| Ultra-low charge injection | ≤5pC guarantees sub-LSB settling in 16-bit+ sample-and-hold circuits without external correction |
| Wide supply flexibility | Operates from +2.7V single supply or ±2.7V dual - eliminates need for dedicated ±5V rails in portable designs |
| ESD robustness | >2000V HBM rating per Method 3015.7 - withstands handling and board-level ESD events without latch-up |
| Pin compatibility | Direct replacement for industry-standard MAX306, DG406, and DG506A - enables drop-in upgrade with no PCB change |

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 architecture, but higher RON (120Ω max) and wider RON matching (15Ω max); no guaranteed charge injection spec | Acceptable where 12-bit accuracy suffices and cost is primary constraint; not suitable for 16-bit+ S&H or low-leakage sensor interfaces | Select MAX306CPI+ only if budget constraints outweigh precision requirements and leakage tolerance is >5nA at +85°C |
| ADG1206BNZ | 16-channel, but requires minimum ±4.5V dual supply; RON = 120Ω typical, charge injection = 20pC typical; no 28-pin DIP option | Requires redesign for dual-rail generation; higher charge injection degrades S&H accuracy; SOIC-28 only - no through-hole option | Choose ADG1206BNZ only if existing design already uses ±5V rails and surface-mount assembly is mandatory |
Compared with MAX306CPI+ and ADG1206BNZ, the MAX396CPI+ uniquely combines 16-channel count, 28-pin DIP packaging, ≤100Ω RON, ≤5pC charge injection, and single-supply down to +2.7V - making it the only option meeting all four criteria for legacy-compatible, high-precision, low-power analog multiplexing.

FAQ
What supply voltages does the MAX396CPI+ support?
The MAX396CPI+ operates from a single +2.7V to +16V supply or dual ±2.7V to ±8V supplies. At +25°C, it functions reliably down to +2.7V single supply or ±2.7V dual supply. Performance is not guaranteed below +2.7V, though functional switching may occur down to +1V during power ramp-up. The MAX396CPI+ pinout accommodates both configurations via dedicated V+, V−, and GND pins.
Is the MAX396CPI+ pin-compatible with older multiplexers?
Yes, the MAX396CPI+ is explicitly pin-compatible with the MAX306, DG406, and DG506A families in the 28-pin DIP package. This includes identical pin assignments for V+, V−, GND, COM, NO1–NO16, A0–A3, EN, and N.C. terminals. No PCB layout changes are required when upgrading from those parts to the MAX396CPI+, provided supply and signal voltage ranges remain within MAX396CPI+ specifications.
What is the maximum analog signal range for the MAX396CPI+?
Under ±5V dual supplies, the MAX396CPI+ supports an analog signal range from V− to V+, i.e., −5V to +5V. With a +5V single supply (V− tied to GND), the range is 0V to +5V. The device maintains guaranteed RON flatness ≤10Ω and low leakage across these full ranges. Exceeding V+ or V− clamps signals via internal diodes - absolute maximum analog voltage is (V− − 2V) to (V+ + 2V).
How does charge injection affect system accuracy with the MAX396CPI+?
The MAX396CPI+ guarantees ≤5pC maximum charge injection, which translates to ≤50µV error on a 100pF sample capacitor - well within 1 LSB of a 16-bit 5V ADC. This low value minimizes settling time and eliminates need for blanking intervals or software correction in precision S&H circuits. Measured charge injection remains ≤2pC typical at +25°C, further enhancing accuracy in low-noise applications using the MAX396CPI+.
What temperature range is specified for the MAX396CPI+?
The MAX396CPI+ is rated for the commercial temperature range of 0°C to +70°C, as indicated by the "C" suffix in its part number. It meets all electrical specifications - including RON, leakage, and switching speed - across this full range. For extended temperature operation, consider the MAX396EPI+ (−40°C to +85°C) or MAX396MJI (−55°C to +125°C), which share identical functionality but different packaging and qualification.
