Analog Devices Inc./Maxim Integrated MAX4700EAE+

Overview

MAX4700EAE+ from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, guaranteed break-before-make switching, 1.25Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling - ideal for precision data acquisition and test equipment where channel isolation and timing control are critical.

For engineers reviewing the MAX4700EAE+ datasheet, MAX4700EAE+ pinout, MAX4700EAE+ application, or MAX4700EAE+ equivalent, key selection criteria include guaranteed break-before-make timing (5–125 ns), R_ON matching (≤0.3Ω), low off-leakage (≤5 nA at +85°C), and TTL/CMOS-compatible logic inputs with independent VL supply.

Technical Context

The MAX4700EAE+ implements two independent SPST analog switches in a single IC: Switch 1 is NC, Switch 2 is NO, with internal logic ensuring break-before-make transition to prevent momentary shorting during state changes. Its CMOS architecture supports rail-to-rail analog signals up to ±20V (dual) or +36V (single), with on-resistance flatness ≤0.3Ω over the full signal range.

It features separate analog (V+, V−, GND) and logic (VL) supplies, enabling TTL/CMOS input compatibility across the entire analog supply range. Input voltage thresholds (VIN_H = 2.4V min, VIN_L = 0.8V max) and <200mA continuous channel current capability support robust interfacing with microcontrollers and industrial signal chains.

Key Specifications

Pinout & Package

MAX4700EAE+ is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65 mm pitch, JEDEC MO-137AC compliant, footprint compatible with industry-standard 16-pin SOIC layouts but with reduced width for space-constrained designs.

FAQ

What is the guaranteed break-before-make time for MAX4700EAE+?

The MAX4700EAE+ guarantees a break-before-make interval of 5 ns minimum to 125 ns maximum under dual-supply conditions (V+ = +15V, V− = −15V). This timing ensures complete isolation between the NC and NO paths before the new connection is established - a critical feature for avoiding signal shorting in multiplexed sensor or calibration circuits. The specification is tested and guaranteed across the full −40°C to +85°C operating range.

Can MAX4700EAE+ operate from a single +12V supply?

Yes, the MAX4700EAE+ supports single-supply operation from +4.5V to +36V. When using +12V, connect V− to GND and configure VL to 3.3V or 5V for TTL/CMOS logic compatibility. Electrical characteristics including R_ON (max 3Ω), leakage (<5 nA), and switching times remain fully specified - confirmed in the "Electrical Characteristics – Single Supply" section of the datasheet.

Does MAX4700EAE+ require external protection diodes for overvoltage?

No, the MAX4700EAE+ integrates internal ESD protection diodes rated for >2 kV HBM, and its absolute maximum ratings (e.g., V+ to GND = −0.3V to +44V) allow direct connection to ±20V rails without external clamping. However, Maxim recommends proper supply sequencing (V+ first, then V−, then logic inputs) - if sequencing cannot be guaranteed, external Schottky diodes may be added per Figure 1 in the datasheet.

What is the maximum analog signal voltage the MAX4700EAE+ can handle?

The MAX4700EAE+ handles rail-to-rail analog signals from V− to V+, supporting ±10V differential swings with full performance. With ±15V supplies, it reliably passes signals from −15V to +15V; with +36V/0V single supply, it supports 0V to +36V. This capability is validated across all electrical specs - including R_ON, leakage, and flatness - and is explicitly stated in the General Description and Absolute Maximum Ratings sections.

Is the MAX4700EAE+ pin-compatible with MAX4680EAE+ or MAX4690EAE+?

No, the MAX4700EAE+ is not pin-compatible with MAX4680EAE+ (dual NC) or MAX4690EAE+ (dual NO). While all three share the same 16-pin SSOP package and core pin assignments (e.g., V+, V−, GND, VL, COM1/COM2), their NC/NO/IN pin mappings differ: MAX4700EAE+ uses Pin 9 for NC1 and Pin 14 for NO2, whereas MAX4680EAE+ places both NC terminals on Pins 9 and 16, and MAX4690EAE+ places both NO terminals there. Board layout must be verified against each device's specific pin configuration diagram.
