Analog Devices Inc./Maxim Integrated MAX4613EEE+

Overview

MAX4613EEE+ from Maxim Integrated is a quad SPST analog switch with two normally open and two normally closed channels, featuring 85Ω max R_DS(ON), 4Ω max on-resistance matching, and 9Ω max on-resistance flatness over ±15V signal range. It operates from single +4.5V to +40V or bipolar ±4.5V to ±20V supplies and delivers <250ns t_ON and <70ns t_OFF for high-speed audio routing and test equipment switching.

For engineers reviewing the MAX4613EEE+ datasheet, MAX4613EEE+ pinout, MAX4613EEE+ application, or MAX4613EEE+ equivalent, key selection criteria include guaranteed R_DS(ON) match across channels, rail-to-rail analog signal handling up to ±15V, low 10pC charge injection for precision sample-and-hold, and -40°C to +85°C industrial temperature rating in QSOP package.

Technical Context

The MAX4613EEE+ implements four independent CMOS-based SPST switches with separate logic-level control (IN1–IN4) and dual analog paths (S/D pairs), supporting both unidirectional and bidirectional conduction. Its internal architecture guarantees matched on-resistance between channels and flat R_DS(ON) across the full analog voltage range under bipolar supply conditions.

Switching is TTL/CMOS-compatible via VL pin (configurable to 5V or V+), with electrostatic discharge protection rated at ≥2000V per Method 3015.7. Off-leakage remains below 5nA at +85°C, enabling reliable operation in battery-powered and high-impedance signal chains without guard-band design overhead.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog signal voltage range supported by the MAX4613EEE+?

The MAX4613EEE+ supports an analog signal range of ±15V under bipolar supply conditions (V+ = +15V, V- = -15V) and 0V to +12V under single-supply operation (V+ = +12V, V- = GND). This rail-to-rail capability allows direct interfacing with standard op-amp outputs and sensor signal chains without external level-shifting circuitry. The device maintains specified R_DS(ON) flatness and leakage performance across this full range.

Does the MAX4613EEE+ require external pull-up or pull-down resistors on its IN1–IN4 control pins?

No, the MAX4613EEE+ does not require external pull-up or pull-down resistors on IN1–IN4. Its logic inputs are CMOS-compatible with defined thresholds (VINH ≥ 2.4V, VINL ≤ 0.8V when VL = 5V) and exhibit low input current (±0.5µA max), allowing direct connection to microcontroller GPIOs or FPGA outputs. Internal ESD protection diodes clamp inputs to V+ and V-, but external resistors are unnecessary for normal operation.

How does the MAX4613EEE+ handle power-supply sequencing, and what happens if V+ is applied after logic signals?

The MAX4613EEE+ recommends applying V+ first, followed by VL, V-, and logic inputs to prevent latch-up or excessive leakage. If sequencing is uncontrolled, internal protection diodes limit input overvoltage, but prolonged violation may cause increased off-leakage or temporary malfunction. The datasheet advises adding external series diodes for robust overvoltage protection in systems lacking strict sequencing - a precaution that preserves MAX4613EEE+ functionality while reducing analog range by ~1V.

Can the MAX4613EEE+ operate with unbalanced supplies such as +24V and -5V?

Yes, the MAX4613EEE+ supports unbalanced supplies like +24V and -5V, provided the absolute voltage difference between V+ and V- does not exceed +44V and each supply remains within its respective absolute maximum rating (V+ ≤ +44V, V- ≥ -44V). This flexibility enables use in hybrid power architectures, such as industrial PLCs with asymmetric auxiliary rails, while maintaining full R_DS(ON) and leakage specifications as long as the analog signal stays within the resulting V- to V+ span.

What is the thermal performance of the MAX4613EEE+ in QSOP package at +85°C ambient?

In its 16-pin QSOP package, the MAX4613EEE+ has a thermal resistance θ_JA of 150°C/W (derating factor 8.3mW/°C above +70°C), enabling 667mW continuous power dissipation at +70°C ambient. At +85°C, derated dissipation is 667mW – (15°C × 8.3mW/°C) = 542mW. Combined with <35µW quiescent power and low R_DS(ON), self-heating remains negligible, ensuring stable on-resistance and leakage performance across the full -40°C to +85°C industrial range.
