Analog Devices Inc./Maxim Integrated MAX4613EEE+T

Overview

The MAX4613EEE+T from Maxim Integrated is a quad, single-pole/single-throw (SPST) analog switch with two normally closed (NC) and two normally open (NO) channels, operating from +4.5V to +40V single supply or ±4.5V to ±20V bipolar supplies. It delivers 85Ω max on-resistance, <5nA off-leakage at +85°C, and 10pC max charge injection-enabling precision signal routing in battery-powered test equipment and audio systems.

For engineers reviewing the MAX4613EEE+T datasheet, MAX4613EEE+T pinout, MAX4613EEE+T application, or MAX4613EEE+T equivalent, key selection criteria include guaranteed R_ON matching (4Ω max), rail-to-rail analog signal handling (±15V), TTL/CMOS logic compatibility, low power consumption (35µW max), and ESD tolerance (2000V min per Method 3015.7).

Technical Context

The MAX4613EEE+T implements four independent SPST switches using high-voltage CMOS process technology, supporting both unipolar and bipolar operation without external level-shifting. Its internal architecture ensures matched on-resistance across all channels and flat R_ON over the full analog signal range (±15V).

Switch control uses active-high logic inputs referenced to VL (5V), with guaranteed switching times of t_ON < 250ns and t_OFF < 70ns under ±10V conditions. The device features integrated ESD protection diodes and supports break-before-make timing to prevent signal shorting during channel transitions.

Key Specifications

Pinout & Package

MAX4613EEE+T is packaged in a 16-pin QSOP (Quarter-Size Outline Package) with 0.15mm lead pitch and exposed pad not present-distinct from the TQFN-EP variant. Pin functions are electrically identical across SO, QSOP, and TSSOP packages per Maxim's ordering table.

FAQ

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

The MAX4613EEE+T supports an analog signal range of ±15V when operated with ±15V supplies, and 0V to +12V with +12V single supply. This range scales linearly with supply voltage-e.g., ±20V supplies enable ±20V signal handling. The device guarantees rail-to-rail operation without signal clipping, making MAX4613EEE+T suitable for high-fidelity audio and industrial sensor interfaces where full dynamic range utilization is critical.

Does the MAX4613EEE+T require external level-shifting for TTL-compatible logic inputs?

No, the MAX4613EEE+T does not require external level-shifting for TTL-compatible logic inputs. When VL is connected to +5V, the device accepts standard TTL thresholds (0.8V low, 2.4V high) directly on IN1–IN4 pins. This eliminates external translators in microcontroller-driven systems. The MAX4613EEE+T also supports CMOS-level inputs by connecting VL to V+, providing design flexibility across different host controller families.

How does the MAX4613EEE+T handle power-supply sequencing during startup?

The MAX4613EEE+T recommends V+ be applied first, followed by VL, V-, and logic inputs to avoid latch-up or excessive leakage. If strict sequencing is impractical, external series diodes on V+ and V- pins provide overvoltage protection-though this reduces analog range by ~1V. The MAX4613EEE+T remains functional with unbalanced supplies (e.g., +24V/–5V), and its internal protection structure maintains reliability even under non-ideal sequencing in field-deployed equipment.

What is the guaranteed on-resistance matching specification for the MAX4613EEE+T, and why does it matter?

The MAX4613EEE+T guarantees on-resistance matching of 4Ω maximum between any two channels under bipolar supply conditions. This tight matching ensures consistent gain and offset across parallel signal paths-critical in applications like multi-channel data acquisition where channel-to-channel crosstalk or gain error must be minimized. Unlike typical analog switches with 10–20Ω matching spreads, the MAX4613EEE+T's 4Ω spec enables high-accuracy differential measurements without per-channel calibration.

Can the MAX4613EEE+T operate with a single +5V supply?

No, the MAX4613EEE+T cannot operate reliably with a single +5V supply. Its absolute minimum single-supply voltage is +4.5V, but electrical characteristics-including R_DS(ON), leakage, and switching speed-are only guaranteed down to +4.5V under specific test conditions. At +5V, R_DS(ON) rises significantly (up to 200Ω), and t_ON/t_OFF degrade beyond datasheet limits. For low-voltage applications, the MAX4613EEE+T is best used with ≥+12V single supply or ±5V bipolar supply to meet full performance specifications.
