Analog Devices Inc./Maxim Integrated MAX4613ETE+

Overview

MAX4613ETE+ from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, designed for precision signal routing in wide-supply-range systems. It delivers 85Ω max R_DS(ON), 4Ω max on-resistance matching between channels, 9Ω max on-resistance flatness over ±15V signal range, <5nA off-leakage at +85°C, and rail-to-rail analog signal handling up to ±20V bipolar or +40V single supply - used in audio routing, test equipment, and military radios.

For engineers reviewing the MAX4613ETE+ datasheet, MAX4613ETE+ pinout, MAX4613ETE+ application, or MAX4613ETE+ equivalent, key selection criteria include guaranteed R_ON match across temperature, low 10pC max charge injection for sample-and-hold integrity, ESD tolerance ≥2000V, TTL/CMOS logic compatibility, and thin QFN-EP package thermal performance.

Technical Context

The MAX4613ETE+ implements four independent CMOS-based SPST switches with separate logic control inputs (IN1–IN4), each driving one drain (D1–D4) and source (S1–S4) pair. Two channels are NO (SW1/SW4), two NC (SW2/SW3), enabling break-before-make or make-before-break configurations depending on control sequencing.

It operates from dual supplies (±4.5V to ±20V) or single supply (+4.5V to +40V), with VL pin configurable for TTL (5V) or CMOS (V+) logic thresholds. Internal ESD protection diodes clamp signals exceeding V+ or V−, and the exposed pad (EP) must be connected to V+ for thermal and electrical stability.

Key Specifications

Pinout & Package

MAX4613ETE+ uses a 16-pin Thin QFN-EP (5mm × 5mm) package with exposed pad (EP) requiring connection to V+. The package supports high thermal dissipation (2667mW at +70°C) and low-inductance grounding via EP.

Compared with MAX4613ETE+, ADG4613BRUZ trades higher on-resistance for extended temperature capability, while TS5A3157DCUR offers ultra-low R_DS(ON) but lacks bipolar support and high-voltage tolerance - making MAX4613ETE+ the optimal choice for industrial test gear and military comms where wide supply range and leakage performance are critical.

FAQ

What is the operating temperature range for the MAX4613ETE+?

The MAX4613ETE+ is rated for operation from −40°C to +85°C, as confirmed by its "E" grade designation in the ordering table and verified across all electrical characteristics (e.g., leakage current <5nA at +85°C). This extended range supports deployment in industrial control cabinets and outdoor military radios where ambient temperatures exceed commercial-grade limits.

Does the MAX4613ETE+ support both single-supply and dual-supply operation?

Yes, the MAX4613ETE+ supports both configurations: single supply from +4.5V to +40V (with V− tied to GND), and dual supply from ±4.5V to ±20V. The VL pin allows logic threshold selection (5V for TTL or V+ for CMOS), and internal clamping diodes protect against signal overvoltage in either mode - a key feature documented in the Applications Information section.

What is the purpose of the exposed pad (EP) on the MAX4613ETE+ package?

The exposed pad (EP) on the MAX4613ETE+ Thin QFN package must be connected to V+ to ensure proper thermal dissipation and electrical stability. Data sheet Pin Description explicitly states "EP = EXPOSED PAD, CONNECT EP TO V+", and the Absolute Maximum Ratings confirm that thermal derating (33.3mW/°C above +70°C) assumes EP-to-V+ connection - omitting this violates the package specification.

How does the MAX4613ETE+ achieve low charge injection, and why does it matter?

The MAX4613ETE+ achieves ≤10pC max charge injection through matched transistor geometry and optimized gate drive timing, as validated in Figure 4 and Electrical Characteristics tables. This matters because low charge injection minimizes voltage glitches on hold capacitors in sample-and-hold circuits - directly enabling accurate 16-bit+ data acquisition without post-capture correction.

Is the MAX4613ETE+ pin-compatible with the DG213?

Yes, the MAX4613ETE+ is explicitly stated as pin-compatible with the industry-standard DG213 in the Features section ("Pin Compatible with Industry-Standard DG213"). Pin mapping (IN1–IN4, D1–D4, S1–S4, V+, V−, GND, VL) matches identically across both devices in 16-pin SO, TSSOP, and QFN packages - confirmed in Pin Description and Ordering Information tables.
