Analog Devices Inc./Maxim Integrated MAX4662CAE

Overview

MAX4662CAE from Maxim Integrated is a quad single-pole single-throw (SPST) analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω maximum on-resistance, 0.5Ω maximum on-resistance match between channels, and 5nA maximum off-leakage current at +85°C, enabling low-distortion switching in data acquisition and test equipment.

For engineers reviewing the MAX4662CAE datasheet, MAX4662CAE pinout, MAX4662CAE application, or MAX4662CAE equivalent, this device is evaluated for high-voltage single-supply (+4.5V to +36V) or dual-supply (±4.5V to ±20V) operation, TTL/CMOS-compatible logic control, and low charge injection (20pC typical) in audio-signal routing and ADC front-end multiplexing.

Technical Context

The MAX4662CAE implements CMOS transmission-gate architecture with independent channel control, supporting rail-to-rail analog signals up to ±20V (dual supply) or 0–36V (single supply). Its on-resistance flatness of ≤0.7Ω over the full signal range ensures minimal THD in audio and instrumentation paths.

Logic inputs are referenced to a dedicated VL pin, decoupling digital interface voltage from analog supply rails - enabling robust operation across mixed-voltage system designs. The device guarantees break-before-make timing only in the MAX4663 variant; MAX4662CAE provides pure NO switching without guaranteed inter-channel sequencing.

FAQ

What is the maximum continuous analog signal voltage range supported by the MAX4662CAE?

The MAX4662CAE supports rail-to-rail analog signals from V− to V+. In single-supply mode (V− = GND), this is 0V to +36V. In dual-supply mode, it handles ±20V - meaning signals from −20V to +20V are fully supported. Absolute maximum ratings allow V+ to V− differentials up to 44V, but operational signal range remains bounded by the supply rails applied to V+ and V− pins.

Does the MAX4662CAE require a negative supply to operate with bipolar signals?

No - the MAX4662CAE can operate with bipolar analog signals using a dual supply (e.g., V+ = +15V, V− = −15V), but it also functions correctly with unipolar signals using a single supply (V− = GND, V+ = +12V). Its rail-to-rail architecture ensures full signal swing from the lowest to highest supply rail, regardless of polarity configuration.

How does the dedicated VL pin affect logic interface design for the MAX4662CAE?

The VL pin sets the reference for logic input thresholds independently of V+ or V−. This allows interfacing with 3.3V or 5V microcontrollers even when analog supplies are ±15V or +30V. VIN_H is guaranteed ≥2.4V and VIN_L ≤0.8V relative to VL, enabling robust noise margins without level-shifting circuitry - a key advantage over switches with supply-referenced logic inputs.

Is the MAX4662CAE pin-compatible with other variants in the MAX466x family?

Yes - MAX4662CAE shares identical pinout and package (16-pin SSOP) with MAX4661CAE and MAX4663CAE. However, internal switch configuration differs: MAX4661CAE is NC, MAX4662CAE is NO, and MAX4663CAE combines two NC and two NO with break-before-make. Swapping requires verifying signal routing and control logic polarity.

What is the typical charge injection value of the MAX4662CAE, and why does it matter in sample-and-hold circuits?

The MAX4662CAE exhibits 20pC typical charge injection. In sample-and-hold applications, injected charge causes voltage step errors on the hold capacitor, directly degrading DC accuracy and increasing settling time. At 20pC into a 10nF hold capacitor, the error is only 2mV - enabling sub-12-bit accuracy without trimming, unlike higher-injection switches requiring external compensation.
