Analog Devices Inc./Maxim Integrated MAX4719EBC-T

Overview

MAX4719EBC-T from Maxim Integrated is a dual single-pole/double-throw (SPDT) analog switch optimized for low-voltage, high-bandwidth signal routing. It delivers 20Ω maximum on-resistance, <80ns turn-on time at +2.7V, and >300MHz -3dB bandwidth in a 12-bump UCSP package (2.0mm × 1.50mm). It supports rail-to-rail analog signals from 0V to V+ and is widely used in audio/video routing and battery-powered portable devices.

For engineers reviewing the MAX4719EBC-T datasheet, MAX4719EBC-T pinout, MAX4719EBC-T application, or MAX4719EBC-T equivalent, key selection criteria include its 0.4Ω R_ON match between channels, break-before-make timing (1ns), +1.8V logic compatibility, and ultra-low 15pF on-channel capacitance - all critical for precision, low-distortion switching in space-constrained, low-power systems.

Technical Context

The MAX4719EBC-T implements two independent SPDT switches using BiCMOS process technology, enabling bidirectional signal flow with rail-to-rail analog handling across the full 0V to V+ range. Its break-before-make architecture prevents momentary shorting during state transitions, and fast t_ON/t_OFF (≤80ns/≤40ns at +2.7V) ensures minimal signal disruption in high-speed data acquisition and sample-and-hold circuits.

It operates from a single +1.8V to +5.5V supply with logic inputs tolerant up to +5.5V regardless of V+, supporting mixed-voltage system interfacing. The UCSP package's 4×3 bump array (0.5mm pitch) enables compact layout while maintaining thermal performance up to +85°C ambient, with derated power dissipation of 909mW at +70°C.

Key Specifications

Pinout & Package

The MAX4719EBC-T is housed in a 12-bump wafer-level chip-scale package (UCSP) measuring 2.0mm × 1.50mm with a 4×3 bump array and 0.5mm bump pitch. This ultra-compact footprint reduces PCB area by >60% versus the 10-pin µMAX variant while maintaining thermal and electrical performance.

FAQ

What is the maximum operating supply voltage for the MAX4719EBC-T?

The MAX4719EBC-T supports a single-supply range from +1.8V to +5.5V. Absolute maximum rating for V+ is +6.0V, but functional operation is guaranteed only within the specified 1.8V–5.5V range. Exceeding +5.5V risks permanent damage per the Absolute Maximum Ratings table.

Does the MAX4719EBC-T support rail-to-rail analog signal switching?

Yes, the MAX4719EBC-T supports rail-to-rail analog signal handling - signals on COM_, NO_, and NC_ terminals can swing from 0V to V+ without clipping or distortion. This is confirmed in the Electrical Characteristics table under "Analog Signal Range" and explicitly stated in the Features section.

What is the on-resistance matching specification for the MAX4719EBC-T at +3.0V supply?

At +3.0V supply, the MAX4719EBC-T guarantees ≤0.4Ω maximum on-resistance match (∆R_ON) between its two SPDT channels. This value is measured under V+ = +2.7V, I_{COM_} = 10mA, and V_{NO_}/V_{NC_} = 1.5V, and is critical for matched gain or phase response in dual-path systems.

Can the digital control inputs of the MAX4719EBC-T tolerate 5V logic when powered from a 1.8V supply?

Yes - the MAX4719EBC-T logic inputs (IN1, IN2) accept voltages up to +5.5V regardless of V+ supply level. With a +1.8V V+, VIH remains +1.4V (min), allowing safe interfacing with 5V microcontrollers without external level shifters, as documented in the Digital I/O section.

Is the UCSP package of the MAX4719EBC-T compatible with standard reflow soldering processes?

The MAX4719EBC-T UCSP package requires adherence to JEDEC J-STD-020A profile (IR/VPR or convection reflow), with preheating mandatory and peak bump temperatures limited to +220°C (infrared) or +215°C (vapor phase). Hand or wave soldering is prohibited, and thermal profiles must follow Maxim's UCSP reliability notice to ensure solder joint integrity.
