Analog Devices Inc./Maxim Integrated MAX4610ESD+

Overview

MAX4610ESD+ from Maxim Integrated is a quad, low-voltage, single-pole/single-throw (SPST), normally open (NO) CMOS analog switch. It operates from a single +2V to +12V supply, delivers ≤100Ω on-resistance at +5V, matches channels within 4Ω max, and supports rail-to-rail analog signal handling (GND to V+). It is used in battery-powered audio routing and low-voltage data-acquisition systems where leakage <2nA at +85°C and >2kV ESD protection are critical.

For engineers reviewing the MAX4610ESD+ datasheet, MAX4610ESD+ pinout, MAX4610ESD+ application, or MAX4610ESD+ equivalent, key selection criteria include guaranteed on-resistance flatness (≤18Ω), TTL/CMOS logic compatibility at +5V, 14-pin narrow SO package dimensions, and automotive-grade temperature range (-40°C to +85°C) without derating.

Technical Context

The MAX4610ESD+ implements four independent NMOS/PMOS complementary-switch pairs with matched threshold voltages to ensure consistent on-resistance across channels and minimal signal distortion. Its control logic accepts standard TTL/CMOS thresholds (0.8V low / 2.4V high at +5V), enabling direct interface with microcontrollers and FPGAs without level-shifting.

Each NO switch routes analog signals from COM_ to NO_ with bidirectional capability, zero-crossing-independent operation, and charge injection of only 1–5pC - critical for sample-and-hold accuracy. Off-isolation exceeds -60dB at 1MHz, and crosstalk remains below -80dB between any two channels.

FAQ

What is the maximum supply voltage rating for MAX4610ESD+?

The absolute maximum V+ rating for MAX4610ESD+ is +13V referenced to GND. Operation above +12V is possible but requires strict adherence to bypassing (0.1µF ceramic capacitor placed adjacent to V+ pin) and thermal derating. Exceeding +13V risks permanent damage, especially under transient conditions.

Does MAX4610ESD+ support bidirectional analog signal flow?

Yes, MAX4610ESD+ supports fully bidirectional analog signal routing between COM_ and NO_ pins. Its CMOS transmission-gate architecture imposes no polarity constraints - signals can pass from COM to NO or NO to COM with identical on-resistance and distortion characteristics.

Is MAX4610ESD+ pin-compatible with the industry-standard 74HC4066?

Yes, MAX4610ESD+ is pin-compatible with the 74HC4066 in the 14-pin narrow SO package. Pin functions (V+, GND, IN1–IN4, COM1–COM4, NO1–NO4) align directly, enabling drop-in replacement with improved on-resistance (100Ω vs. ~120Ω), lower leakage, and enhanced ESD robustness.

What is the typical charge injection value for MAX4610ESD+ and why does it matter?

MAX4610ESD+ exhibits 1–5pC typical charge injection. This parameter quantifies the net charge dumped onto the signal path during switching transitions - critical in sample-and-hold and switched-capacitor circuits, where excess charge causes voltage glitches and settling errors that degrade ADC accuracy.

Can MAX4610ESD+ operate from a +3V supply, and what are the key trade-offs?

Yes, MAX4610ESD+ operates from +3V. At this supply, on-resistance increases to 175–360Ω (vs. 100Ω at +5V), and turn-on time extends to 140ns (vs. 65ns). However, logic thresholds remain valid (VIN_L ≤ 0.5V, VIN_H ≥ 2.4V), and leakage stays ≤2nA - making it viable for ultra-low-power wake-up signal routing.
