Analog Devices Inc./Maxim Integrated MAX4606ESE

Overview

MAX4606ESE from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, 5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling - used in precision audio routing and automated test equipment where low distortion and channel matching are critical.

For engineers reviewing the MAX4606ESE datasheet, MAX4606ESE pinout, MAX4606ESE application, or MAX4606ESE equivalent, key selection criteria include guaranteed R_ON match (≤0.5Ω), off-leakage ≤2.5nA at +85°C, TTL/CMOS-compatible logic thresholds, and SO-16 package compatibility with industrial temperature range (-40°C to +85°C).

Technical Context

The MAX4606ESE implements four independent CMOS SPST switches in a single monolithic IC, with dedicated NO and NC terminals per channel and shared COM pins. Its architecture ensures matched on-resistance across all four channels and flat R_ON (≤0.5Ω variation) over the full ±10V analog signal range under dual supply.

Logic control uses VL-referenced inputs with fixed TTL/CMOS thresholds (0.8V low, 2.4V high), enabling direct interface with +5V logic while operating from ±15V analog supplies. Internal ESD protection exceeds 2000V per Method 3015.7, and all analog pins tolerate signals beyond V+/V− via clamping diodes.

Key Specifications

Pinout & Package

MAX4606ESE is housed in a 16-pin narrow SOIC (SO/DIP) package, 3.9mm width, with standard 1.27mm pitch and exposed pad not present. Pin 1 is marked by notch or dot; device orientation follows JEDEC MS-012.

The MAX4604/MAX4605/MAX4606 family was designed specifically for high-precision, low-distortion analog switching in environments demanding rail-to-rail signal handling, tight R_ON matching, and robust operation across wide supply and temperature ranges.

FAQ

What is the maximum analog signal voltage range supported by the MAX4606ESE?

The MAX4606ESE supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. Under normal operation, it handles ±10V signals with guaranteed 5Ω R_ON and 0.5Ω flatness - verified across −40°C to +85°C.

Does the MAX4606ESE require separate logic and analog supplies?

Yes - the MAX4606ESE uses three supply connections: V+ (analog positive), V− (analog negative), and VL (logic supply). VL may be tied to V+ or a dedicated +5V rail; it sets logic thresholds and must remain within 2.7V to V+. V− can be grounded for single-supply use (+4.5V to +36V), but dual-supply operation requires both V+ and V−.

How does the two-NO/two-NC configuration of the MAX4606ESE differ from the MAX4604 and MAX4605?

The MAX4606ESE integrates two normally open (NO) and two normally closed (NC) switches in one SO-16 package - unlike the MAX4604ESE (four NC only) or MAX4605ESE (four NO only). This allows hybrid switching schemes such as break-before-make, redundant path selection, or self-test loops where continuity must be maintained during fault conditions.

Can the MAX4606ESE be used in high-frequency RF applications above 10MHz?

No - the MAX4606ESE is optimized for DC to ~3MHz analog switching. Above 5MHz, layout sensitivity increases significantly, and off-isolation degrades rapidly (e.g., −60dB at 1MHz drops to <−20dB at 100MHz). For RF applications up to 160MHz, Maxim recommends the MAX440/MAX441/MAX442 series, which are fully characterized for high-frequency performance.

What is the thermal performance of the MAX4606ESE in its SO-16 package?

The MAX4606ESE in narrow SOIC (16-pin) has a thermal resistance θ_JA of 115°C/W and a maximum continuous power dissipation of 696mW at +70°C ambient (derated 8.70mW/°C above). It operates reliably from −40°C to +85°C, with R_ON drift less than 10% across that range - confirmed by characterization curves in the datasheet.
