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 DG411/DG412/DG413 layouts.

Technical Context

The MAX313CSE+ implements a fully complementary CMOS transmission-gate architecture with matched P- and N-channel devices per channel, 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) independent of analog supply rails.

It supports true rail-to-rail analog signal switching across its full specified range, with on-resistance variation tightly controlled (<2Ω flatness) over ±10V signal swing and temperature (–40°C to +85°C for E-grade; this CSE+ variant is 0°C to +70°C). Break-before-make timing is not inherent - each SPST switch operates independently without internal interlock.

Key Specifications

Pinout & Package

MAX313CSE+ is housed in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package, 3.9mm wide, with standard 1.27mm pitch and gull-wing leads. Pin 1 is marked by a beveled corner or dot; device orientation follows JEDEC MS-012.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs high-performance analog, mixed-signal, and power management ICs for demanding industrial, communications, and computing applications.

The MAX312/MAX313/MAX314 family was engineered specifically for low-distortion, high-fidelity analog signal routing in test, measurement, and audio systems where R_ON matching, leakage, and crosstalk are critical.

FAQ

What is the maximum supply voltage rating for MAX313CSE+?

The MAX313CSE+ supports dual supplies from ±4.5V to ±20V, or a single supply from +4.5V to +30V. Absolute maximum ratings specify V+ up to +44V and V− down to –44V, but functional operation is guaranteed only within the specified supply ranges. Exceeding ±20V or +30V risks parametric degradation or damage, even if within absolute max limits.

Does MAX313CSE+ require an external logic supply (VL), or can it be tied to V+?

The VL pin on MAX313CSE+ must be supplied with a stable voltage between (GND – 0.3V) and (V+ + 0.3V); it is commonly tied to +5V or V+ for TTL/CMOS compatibility. Tying VL directly to V+ is permissible and often used in single-supply systems, provided V+ is within 2.4V–5.5V for reliable logic thresholds - outside that range, a dedicated 5V VL source is recommended.

Is MAX313CSE+ pin-compatible with the DG411, and what does that mean for PCB design?

Yes, MAX313CSE+ is explicitly pin-compatible with the DG411, sharing identical pin functions, numbering, and SOIC-16 footprint. This means existing PCBs designed for DG411 can accept MAX313CSE+ without layout changes - delivering lower on-resistance (6.5Ω vs. ~35Ω), better matching, and enhanced ESD robustness while preserving full functional equivalence.

What is the typical turn-on time for MAX313CSE+, and how does it vary with supply voltage?

MAX313CSE+ exhibits 65ns typical turn-on time (t_ON) at +15V/–15V supplies and 25°C. Under single-supply conditions (+12V, V− = 0V), t_ON increases to 125ns. The parameter is load-dependent (RL = 50Ω, CL = 5pF); heavier capacitive loads or lower supply voltages further increase switching time, affecting high-speed multiplexing feasibility.

Can MAX313CSE+ safely switch AC-coupled signals that swing below GND in a single-supply configuration?

No - in single-supply mode (V− = GND), the MAX313CSE+ cannot reliably pass signals with negative excursions below GND. Its analog signal range is limited to 0V to V+. To handle bipolar AC signals, dual-supply operation (e.g., V+ = +15V, V− = –15V) is mandatory, enabling true rail-to-rail switching from –15V to +15V without clipping or distortion.
