Analog Devices Inc./Maxim Integrated MAX4782EUE+T

Overview

MAX4782EUE+T from Maxim Integrated is a high-speed, low-voltage dual 4-channel CMOS analog multiplexer configured for bidirectional signal routing in portable and low-power systems. It features 0.7Ω on-resistance at +3V supply, 11ns turn-on time, ±150mA continuous current handling, rail-to-rail analog signal support, and operates from +1.6V to +3.6V. It is used in audio signal routing and low-voltage data-acquisition systems where channel matching and fast switching are critical.

For engineers reviewing the MAX4782EUE+T datasheet, MAX4782EUE+T pinout, MAX4782EUE+T application, or MAX4782EUE+T equivalent, this page delivers verified electrical parameters, TSSOP-16 pin mapping, real-world use scenarios, and two confirmed alternative parts with documented functional and application-level differences.

Technical Context

The MAX4782EUE+T implements two independent 4:1 analog multiplexers (X and Y sections), each controlled by 2-bit address inputs (A, B) and a shared ENABLE input. Its CMOS switch architecture supports bidirectional signal flow with no polarity constraints, and internal ESD diodes clamp analog inputs to VCC/GND.

It uses a single-supply +1.6V to +3.6V interface with +1.8V CMOS logic compatibility, delivering 0.3Ω on-resistance matching and 0.1Ω flatness at +3V - enabling precision multiplexing in battery-powered instrumentation and audio codecs without external level-shifting.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog signal voltage range supported by the MAX4782EUE+T?

The MAX4782EUE+T supports rail-to-rail analog signals from 0V to VCC. When powered from a +3.3V supply, it passes signals from 0V to +3.3V without clipping or distortion. This capability is confirmed in the Electrical Characteristics table under "Analog Signal Range" and applies across the full operating temperature range of –40°C to +85°C. The MAX4782EUE+T achieves this using internal CMOS switch architecture with ESD diodes clamped to VCC and GND.

Does the MAX4782EUE+T require external pull-up or pull-down resistors on its address pins (A, B)?

No, the MAX4782EUE+T does not require external pull-up or pull-down resistors on A or B address pins. Its digital inputs meet +1.8V CMOS logic thresholds (VIH = 1.4V min, VIL = 0.5V max at +3V supply), and input leakage is limited to ±1µA - low enough to allow direct connection to microcontroller GPIOs. Internal design ensures stable logic interpretation without external biasing, as verified in the DIGITAL I/O section of the datasheet.

Can the MAX4782EUE+T be used in bidirectional signal paths, such as between an ADC and multiple sensors?

Yes, the MAX4782EUE+T supports fully bidirectional analog signal flow. Its CMOS switch structure has no intrinsic directionality: X and Y outputs can serve as inputs, and X0–X3/Y0–Y3 inputs can act as outputs. This is explicitly stated in the Applications Information section ("Input and output pins are identical and interchangeable") and validated by symmetric on-resistance, leakage, and capacitance specs for all terminals. The MAX4782EUE+T is routinely deployed in sensor multiplexing and codec interfacing where signals flow both ways.

What is the thermal performance difference between MAX4782EUE+T (TSSOP) and MAX4782ETE+ (QFN)?

The MAX4782ETE+ in 3mm × 3mm thin QFN offers significantly better thermal performance than the MAX4782EUE+T in TSSOP: its thermal resistance θJA is 118°C/W versus 219°C/W for the TSSOP. This 46% reduction enables higher continuous current handling under sustained load and improves reliability in compact enclosures. The QFN's exposed pad (connected to GND) provides a low-impedance thermal path, while the TSSOP relies solely on leads and PCB copper. Both parts share identical electrical specs.

Is the ENABLE pin of the MAX4782EUE+T active-high or active-low?

The ENABLE pin of the MAX4782EUE+T is active-high. When driven to logic high (≥1.4V at +3V supply), it forces all internal switches into the open (off) state, disconnecting all analog paths. When held low (≤0.5V), the device responds to address inputs A and B to route selected channels. This behavior is defined in the Pin Description table and confirmed in Table 1 (Truth Table), where "ENABLE = H" results in "All switches open" regardless of A/B/C states.
