Analog Devices Inc./Maxim Integrated MAX4700CAE+T

Overview

MAX4700CAE+T 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 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 MAX4700CAE+T datasheet, MAX4700CAE+T pinout, MAX4700CAE+T application, or MAX4700CAE+T 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 MAX4700CAE+T implements two independent SPST analog switches in a single IC: Switch 1 is NC (closed when IN1 = 0), Switch 2 is NO (closed when IN2 = 1), with hard-wired break-before-make behavior ensuring no overlap during state transitions. Its CMOS transmission-gate architecture supports bidirectional rail-to-rail analog signals up to ±20V (dual) or +36V (single).

It features separate analog (V+, V−, GND) and logic (VL) supplies, enabling mixed-voltage system interfacing; input logic thresholds (VIN_H = 2.4V, VIN_L = 0.8V) remain valid across full analog supply ranges, and internal ESD protection exceeds 2kV per Method 3015.7.

FAQ

What is the guaranteed break-before-make timing specification for MAX4700CAE+T?

The MAX4700CAE+T guarantees a break-before-make interval of 5 ns minimum to 125 ns maximum under dual-supply conditions (V+ = +15V, V− = −15V, TA = TMIN to TMAX). This timing ensures no overlap between NC and NO switch conduction states, preventing transient shorts in multiplexer or signal-routing configurations. The value is measured between 50% points of the control inputs and verified across temperature and supply variations.

Can MAX4700CAE+T operate from a single +12V supply?

Yes, MAX4700CAE+T supports single-supply operation from +4.5V to +36V. When using +12V, connect V− to GND, set VL to +5V (or compatible logic level), and ensure all analog signals remain within 0V to +12V. On-resistance remains ≤1.25Ω, and off-leakage stays ≤5 nA at +85°C - confirmed in the Single-Supply Electrical Characteristics table of the datasheet.

What is the maximum continuous current rating per switch terminal of MAX4700CAE+T?

The MAX4700CAE+T supports ±200 mA continuous current through each COM_, NO_, or NC_ terminal, as specified in the Absolute Maximum Ratings table. This rating applies across the full operating temperature range and assumes proper PCB thermal design. Peak pulsed current (1 ms, 10% duty cycle) is ±300 mA - sufficient for driving moderate loads like op-amp inputs or ADC references.

Does MAX4700CAE+T require external pull-up or pull-down resistors on its IN1/IN2 pins?

No, MAX4700CAE+T does not require external biasing on IN1 or IN2. Its TTL/CMOS-compatible inputs have defined thresholds (VIN_H = 2.4V min, VIN_L = 0.8V max) and low input current (±0.5 µA typical), allowing direct connection to microcontroller GPIOs or logic gates. Internal circuitry ensures clean switching without floating-input risk - provided VL is properly supplied.

How does the separate VL pin benefit system design with MAX4700CAE+T?

The dedicated VL pin on MAX4700CAE+T decouples logic-level signaling from analog supply noise, enabling reliable control even when V+ and V− swing widely (e.g., ±15V). It allows use of 3.3V or 5V logic sources regardless of analog rail voltages, simplifies level-shifting, improves noise immunity, and eliminates timing skew caused by supply-dependent input thresholds - a key advantage over fixed-threshold analog switches.
