Analog Devices Inc./Maxim Integrated MAX4700CPE

Overview

MAX4700CPE from Maxim Integrated is a dual single-pole/single-throw (SPST) CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, guaranteed break-before-make switching, 1.25Ω maximum on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail analog signal handling - ideal for precision data acquisition and test equipment where channel isolation and timing control are critical.

For engineers reviewing the MAX4700CPE datasheet, MAX4700CPE pinout, MAX4700CPE application, or MAX4700CPE equivalent, key selection criteria include verified break-before-make timing (5ns min), R_ON matching (≤0.3Ω), off-leakage current (≤5nA at +85°C), and TTL/CMOS-compatible logic inputs with separate VL supply for mixed-voltage system interfacing.

Technical Context

The MAX4700CPE implements two independent SPST switches in a single IC: Switch 1 is NC (closed when IN1 = 0), Switch 2 is NO (open when IN2 = 0), with guaranteed break-before-make behavior ensuring no overlap during state transitions. Its CMOS transmission-gate architecture supports rail-to-rail analog signals up to ±20V (dual supply) or 0–36V (single supply).

It features a dedicated VL pin enabling logic-level compatibility across the full analog supply range, internal ESD protection (>2kV per Method 3015.7), and matched on-resistance flatness (≤0.3Ω over ±10V signal range), making it suitable for low-distortion multiplexing and sample-and-hold circuits requiring precise charge control.

Key Specifications

Pinout & Package

MAX4700CPE is housed in a 16-pin plastic DIP package (0.3-inch width), through-hole mountable, with 0°C to +70°C operating temperature range and standard JEDEC MO-011AC footprint.

FAQ

What is the guaranteed break-before-make timing specification for the MAX4700CPE?

The MAX4700CPE guarantees a minimum break-before-make interval of 5ns, measured under dual-supply conditions (V+ = +15V, V− = −15V). This timing ensures complete disconnection of the first switch before the second closes, preventing momentary shorts in critical signal routing applications. The specification is tested and guaranteed across the full operating temperature range (0°C to +70°C) and appears in the Electrical Characteristics table under "tOPEN".

Can the MAX4700CPE operate from a single +12V supply, and what are the logic interface requirements?

Yes, the MAX4700CPE supports single-supply operation from +4.5V to +36V - including +12V - with V− tied to GND. Logic inputs remain fully TTL/CMOS-compatible via the dedicated VL pin, which can be set to +3.3V or +5V independently. This allows microcontrollers with lower I/O voltages to reliably control the switch without level-shifting, even when analog rails exceed logic supply levels.

What is the maximum allowable analog signal range when using the MAX4700CPE with ±15V supplies?

With ±15V analog supplies (V+ = +15V, V− = −15V), the MAX4700CPE supports true rail-to-rail analog signals from −15V to +15V on all COM, NC, and NO terminals. This full-range capability is enabled by its CMOS transmission-gate architecture and internal protection diodes, and is confirmed in the Absolute Maximum Ratings and Electrical Characteristics sections for both dual- and single-supply configurations.

How does the MAX4700CPE's on-resistance matching benefit precision measurement applications?

The MAX4700CPE guarantees ≤0.3Ω maximum on-resistance mismatch (∆R_ON) between its two switches. In precision applications like ratiometric sensor bridges or differential multiplexing, this tight matching minimizes gain error and channel-to-channel offset - eliminating the need for per-channel calibration and improving overall system accuracy without additional compensation circuitry.

Is the MAX4700CPE pin-compatible with other devices in the MAX4680/MAX4690/MAX4700 family?

Yes, the MAX4700CPE shares identical pinout and package (16-pin plastic DIP) with MAX4680CPE and MAX4690CPE. However, internal switch configuration differs: MAX4680CPE has two NC switches, MAX4690CPE has two NO switches, and MAX4700CPE has one NC and one NO with break-before-make. Board layout is interchangeable, but logic control sequencing must match the intended switching behavior.
