Analog Devices Inc./Maxim Integrated MAX4613ESE+T

Overview

MAX4613ESE+T from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, designed for precision signal routing in ±4.5V to ±20V or +4.5V to +40V supply systems. It delivers 85Ω max on-resistance, 4Ω max R_ON match between channels, 9Ω max R_FLAT(ON), 10pC max charge injection, and <5nA off-leakage at +85°C - enabling high-fidelity audio routing and sample-and-hold circuits.

For engineers reviewing the MAX4613ESE+T datasheet, MAX4613ESE+T pinout, MAX4613ESE+T application, or MAX4613ESE+T equivalent, key selection criteria include guaranteed bipolar/single-supply operation, rail-to-rail analog signal handling (±15V), TTL/CMOS logic compatibility, low crosstalk (100dB), and ESD tolerance of ≥2000V per Method 3015.7.

Technical Context

The MAX4613ESE+T implements four independent CMOS transmission gates with complementary control logic: IN1–IN4 directly drive respective switches, where logic low enables NC paths (SW1/SW4) and logic high enables NO paths (SW2/SW3). Its architecture guarantees matched on-resistance across all channels under bipolar supply conditions, critical for differential signal integrity.

It supports true rail-to-rail analog voltage swing (±15V with ±15V supplies), features break-before-make timing (5–20ns), and maintains low dynamic parameters: t_ON < 250ns and t_OFF < 70ns at ±10V. Charge injection is tightly controlled (≤10pC) via internal gate-oxide optimization and layout symmetry.

Key Specifications

Pinout & Package

MAX4613ESE+T is packaged in a 16-pin narrow SO (Small Outline) with exposed pad connected to V+. Pin functions are electrically identical across SO/QSOP/TSSOP/DIP variants per Maxim's ordering table.

FAQ

What is the operating temperature range for MAX4613ESE+T?

The MAX4613ESE+T is rated for -40°C to +85°C operation, as confirmed by its "E" grade suffix in the ordering table and electrical characteristics tested across this full range. This makes it suitable for industrial and automotive under-hood applications where ambient temperatures exceed commercial-grade limits. All key parameters - including on-resistance match, off-leakage, and switching times - are guaranteed over this extended temperature span.

Does MAX4613ESE+T support both single-supply and dual-supply operation?

Yes, MAX4613ESE+T operates from either a single +4.5V to +40V supply (with V- tied to GND) or bipolar ±4.5V to ±20V supplies. The datasheet specifies distinct electrical characteristics for both configurations, including analog signal range (0–12V unipolar vs. ±15V bipolar) and on-resistance flatness (guaranteed only under bipolar conditions). This dual-mode capability allows reuse across diverse system architectures without redesign.

What is the function of the VL pin on MAX4613ESE+T?

The VL pin on MAX4613ESE+T sets the logic threshold voltage: connect VL to +5V for TTL-compatible inputs (2.4V high, 0.8V low), or tie VL to V+ for CMOS-level compatibility. This flexibility enables direct interfacing with both legacy microcontrollers and modern low-voltage FPGAs. The pin is not optional - incorrect VL configuration results in undefined switching behavior or increased logic current consumption.

Is MAX4613ESE+T pin-compatible with industry-standard analog switches?

Yes, MAX4613ESE+T is explicitly pin-compatible with the industry-standard DG213, as stated in the Features section of the datasheet. This includes identical pin numbering, terminal functions (INx, Dx, Sx, V+, V-, GND, VL), and package footprint for SO, QSOP, TSSOP, and DIP variants. No PCB layout changes are required when upgrading from DG213 to MAX4613ESE+T.

How does MAX4613ESE+T handle overvoltage conditions on analog pins?

MAX4613ESE+T includes internal ESD protection diodes that clamp analog pins (Sx, Dx) to V+ and V- rails. However, the Absolute Maximum Ratings specify that signals must not exceed V+ or V- by more than 2V. For overvoltage events beyond this limit - such as hot-plug transients - external series diodes (as shown in Figure 1 of the datasheet) are recommended to prevent latch-up and ensure long-term reliability of the MAX4613ESE+T.
