Analog Devices Inc./Maxim Integrated MAX313CSE

Overview

MAX313CSE from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) CMOS analog switch optimized for precision signal routing in bipolar and single-supply systems. It delivers 6.5Ω typical on-resistance, 1.5Ω max on-resistance matching between channels, and rail-to-rail analog signal handling from ±4.5V to ±20V dual supplies or +4.5V to +30V single supply - enabling low-distortion audio routing and high-fidelity data acquisition.

For engineers reviewing the MAX313CSE datasheet, MAX313CSE pinout, MAX313CSE application, or MAX313CSE equivalent, key selection criteria include guaranteed R_ON flatness (≤2Ω), <2.5nA off-leakage at +85°C, >96dB crosstalk at 20kHz, ESD tolerance >2000V per Method 3015.7, and compatibility with DG412-level control logic in test equipment and avionics signal paths.

Technical Context

The MAX313CSE implements four independent NO switches using CMOS transmission-gate architecture with matched P- and N-channel devices, ensuring symmetrical conduction and minimal charge injection (±30pC). Its logic interface accepts TTL/CMOS-compatible inputs referenced to VL (2.4V high, 0.8V low) and operates across industrial temperature range (0°C to +70°C).

Internal overvoltage protection diodes clamp analog pins to V+ and V−, allowing safe operation with signals exceeding supply rails by up to 2V. The device maintains ≤10Ω max on-resistance over full analog signal range (±10V) and temperature, with R_ON flatness tightly controlled to support precision instrumentation and sample-and-hold circuits.

Key Specifications

Pinout & Package

MAX313CSE is housed in a 16-pin narrow SOIC (SO) package (JEDEC MS-012, 3.9mm width), with 1.27mm pitch and surface-mount footprint. Pin 1 is marked via notch or dot; thermal pad not present.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs high-performance analog and mixed-signal ICs for precision, power, and interface applications - with emphasis on reliability, integration, and ruggedness in harsh environments.

The MAX312/MAX313/MAX314 family was engineered specifically for low-distortion, low-leakage analog signal routing in test, measurement, and aerospace systems where channel matching and rail-to-rail operation are essential.

FAQ

What is the operating temperature range for the MAX313CSE?

The MAX313CSE is specified for commercial temperature operation from 0°C to +70°C. This grade is validated per the MAX31_C_ ordering suffix and applies to the narrow SOIC package variant. It is not rated for extended industrial (−40°C to +85°C) or military (−55°C to +125°C) ranges - those require MAX313ESE or MAX313MJE variants respectively.

Can the MAX313CSE operate from a single 5V supply?

Yes, the MAX313CSE supports single-supply operation from +4.5V to +30V. With V+ = 5V and V− tied to GND, it delivers rail-to-rail analog switching from 0V to 5V. However, R_ON increases to ~12.5Ω (typical) under these conditions - verify signal integrity and voltage drop in low-voltage, high-current paths using the single-supply R_ON vs. VCOM curves in the datasheet.

Is the MAX313CSE pin-compatible with the DG412?

Yes, the MAX313CSE is explicitly designed as a pin-compatible upgrade to the DG412. Pin assignments, footprint, and logic polarity match exactly - enabling drop-in replacement without PCB modification. Key improvements include lower R_ON (6.5Ω vs. 90Ω), tighter R_ON matching (1.5Ω vs. unspecified), and enhanced ESD tolerance (>2000V vs. ~200V).

What is the maximum analog signal voltage the MAX313CSE can handle?

The MAX313CSE supports analog signals from V− to V+, with absolute maximum ratings of (V− − 2V) to (V+ + 2V) on NC/NO/COM pins. For example, with V+ = +15V and V− = −15V, signals up to ±17V are clamped safely by internal diodes - but sustained operation above ±10V may increase leakage and degrade R_ON flatness. Always limit forward diode current to ≤30mA.

Does the MAX313CSE require an external logic supply (VL)?

Yes, VL (Pin 12) must be supplied independently - typically 5V or 3.3V - to establish logic thresholds and power internal level shifters. VL range is 2.0V to 5.5V. Leaving VL unconnected or floating will disable logic functionality. VL may be tied to V+ only if V+ ≤ 5.5V; otherwise, a separate regulated source is mandatory for reliable INx recognition.
