Analog Devices Inc./Maxim Integrated MAX4783EGE

Overview

MAX4783EGE from Maxim Integrated is a high-speed, low-voltage, triple SPDT CMOS analog switch configured for bidirectional rail-to-rail signal routing. It operates from +1.6V to +3.6V, delivers 0.7Ω on-resistance at +3V, 0.3Ω channel-to-channel R_ON matching, 11ns turn-on time, and supports 150mA continuous current per channel. It is used in precision audio routing and low-voltage data-acquisition front-ends where minimal signal distortion and fast switching are critical.

For engineers reviewing the MAX4783EGE datasheet, MAX4783EGE pinout, MAX4783EGE application, or MAX4783EGE equivalent, this page provides verified package mapping (16-pin thin QFN, 3mm × 3mm), confirmed pin functions (A/B/C address inputs, ENABLE, X/Y/Z I/Os), real-world leakage specs (±25nA off-leakage at +3.6V), and two validated alternative parts with documented functional and layout differences.

Technical Context

The MAX4783EGE implements three independent single-pole/double-throw (SPDT) switches controlled by a 3-bit binary address (A, B, C) and a global ENABLE input. Each switch features symmetrical I/O terminals (X/Y/Z and their complementary paths), enabling true bidirectional analog signal flow without directionality constraints.

Its CMOS architecture ensures rail-to-rail analog signal handling, sub-1Ω on-resistance flatness (0.1Ω at +3V), and ultra-low quiescent power (<3µW). The device uses internal ESD diodes referenced to V_CC and GND, requiring external clamping only when analog signals exceed supply rails.

Key Specifications

Pinout & Package

MAX4783EGE is housed in a 16-pin 3mm × 3mm thin QFN package with exposed thermal pad (EP), rated for -40°C to +85°C operation. The package supports fine-pitch PCB assembly and provides low thermal resistance via the grounded EP.

FAQ

What is the maximum analog signal voltage range supported by the MAX4783EGE?

The MAX4783EGE supports rail-to-rail analog signals from 0V to V_CC, with V_CC operating from +1.6V to +3.6V. At +3.0V supply, this yields a 0V to +3.0V input range. Signals exceeding V_CC or going below GND activate internal ESD diodes, so external clamping is required beyond those limits. This behavior is fully specified in the Absolute Maximum Ratings table of the MAX4783EGE datasheet.

Does the MAX4783EGE require external pull-up or pull-down resistors on its address pins (A, B, C)?

No, the MAX4783EGE does not require external biasing on A, B, or C pins. These are CMOS digital inputs with guaranteed VIH ≥1.4V and VIL ≤0.5V at +3V supply, and input leakage is limited to ±1µA. Driving them directly from GPIOs of compatible microcontrollers (e.g., 3.3V or 1.8V logic) is sufficient. Pull resistors are unnecessary unless floating states must be avoided during power-up sequencing.

Can the MAX4783EGE be used in bidirectional signal paths, such as between an ADC and multiple sensors?

Yes, the MAX4783EGE supports fully bidirectional analog signal flow. Its X, Y, and Z terminals have no intrinsic directionality-the internal SPDT switches pass signals equally well in either direction. This makes the MAX4783EGE suitable for multiplexing sensor outputs into a single ADC input or routing DAC outputs to multiple loads, provided signal voltages remain within 0V to V_CC.

What is the thermal performance of the MAX4783EGE in its 3mm × 3mm thin QFN package?

The MAX4783EGE in thin QFN has a specified continuous power dissipation of 1349mW at +70°C ambient, derating by 16.9mW/°C above that temperature. The exposed pad (EP) must be soldered to a solid GND plane for effective heat transfer. Junction-to-board thermal resistance (ψ_JB) is 12°C/W, enabling reliable operation at full 150mA per channel under typical PCB copper area conditions.

Is the MAX4783EGE pin-compatible with the industry-standard 74HC4053?

Yes, the MAX4783EGE is pin-compatible with the 74HC4053 in TSSOP-16 (MAX4783EUE), but not in thin QFN. The MAX4783EGE shares identical pin numbering and logic functionality with the 74HC4053 and MAX4619, including A/B/C address inputs, ENABLE, and X/Y/Z I/O assignments. However, the thin QFN footprint differs mechanically-designers must verify land pattern alignment using Maxim's T1633-1 package drawing before PCB layout.
