Analog Devices Inc./Maxim Integrated MAX4052EEE+

Overview

MAX4052EEE+ from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional rail-to-rail signal routing in low-voltage systems. It supports ±2.7V to ±8V dual supplies or +2.7V to +16V single supply, delivers 100Ω typical on-resistance at ±5V, guarantees ≤12Ω channel-to-channel on-resistance match (non-A version), and exhibits 0.1nA max off-leakage at +25°C. It is used in battery-powered data-acquisition front-ends where precision analog switching and low power are critical.

For engineers reviewing the MAX4052EEE+ datasheet, MAX4052EEE+ pinout, MAX4052EEE+ application, or MAX4052EEE+ equivalent, key selection criteria include guaranteed on-resistance flatness, TTL/CMOS logic compatibility across supply ranges, break-before-make timing control, low charge injection (<10pC), and verified performance in audio routing and sensor multiplexing under ±5V or +5V operation.

Technical Context

The MAX4052EEE+ implements two independent 4:1 analog multiplexers using complementary CMOS switch architecture with level-translated digital inputs. Each section uses three address bits (ADDA, ADDB, INH) to select one of four NOx inputs to connect to its COM terminal, with no internal decoding-address logic is fully transparent and synchronous.

It features internally protected ESD diodes between all analog pins and V+/V−, enabling robust rail-to-rail signal handling up to ±8V while maintaining sub-nA leakage. Its analog path is fully isolated from GND, allowing floating signal domains, and its logic interface operates independently from analog supply rails via dedicated V+ and GND pins.

FAQ

What supply configurations does the MAX4052EEE+ support?

The MAX4052EEE+ supports dual supplies from ±2.7V to ±8V and single supplies from +2.7V to +16V. When using single supply, V− must be tied to GND. The device maintains rail-to-rail analog signal handling across all valid supply ranges, and logic thresholds scale appropriately - e.g., VIH remains 2.4V at +5V supply, ensuring TTL/CMOS compatibility without external translation. This flexibility allows direct use in both legacy ±5V systems and modern low-voltage battery-powered designs.

How does the MAX4052EEE+ handle channel selection and disable control?

The MAX4052EEE+ uses three digital inputs - ADDA, ADDB, and INH - to manage two independent 4:1 multiplexers. ADDA and ADDB directly encode the selected channel (00–11) for each section; INH is an active-high inhibit that forces all switches open regardless of address state. There is no internal decoder - the logic is fully transparent and synchronous. This design simplifies timing analysis and avoids propagation delays associated with integrated decoding, making the MAX4052EEE+ predictable in real-time control loops.

What is the maximum guaranteed on-resistance match between channels in the MAX4052EEE+?

The MAX4052EEE+ guarantees a maximum on-resistance match (ΔRON) of 12Ω between any two channels within the same multiplexer section, measured at TA = +25°C with V+ = 5V and V− = –5V. This specification applies to the non-A version (MAX4052, not MAX4052A), and is confirmed by production testing. The match ensures consistent gain and offset behavior across channels - critical for ratiometric measurements and multi-channel calibration routines in precision data-acquisition systems.

Can the MAX4052EEE+ be used in AC-coupled audio paths without DC bias concerns?

Yes, the MAX4052EEE+ can be used in AC-coupled audio paths because its analog path is fully GND-isolated: NO and COM pins have no internal reference to GND and operate strictly between V+ and V−. Signals swing rail-to-rail without requiring DC biasing networks. However, coupling capacitors must be sized to accommodate the device's 2pF NO/COM off-capacitance and maintain low-frequency response. The <–90dB crosstalk and <0.04% THD at 1kHz further confirm suitability for line-level stereo routing without audible artifacts.

What is the thermal performance limit for continuous operation of the MAX4052EEE+?

The MAX4052EEE+ is rated for continuous operation from –40°C to +85°C, as defined by its "E" grade temperature specification and QSOP package construction. Its maximum power dissipation is 640mW at TA = +70°C, derating at 8.00mW/°C above that point. At full temperature range, leakage currents remain within spec (e.g., 5nA max off-leakage at +85°C), and on-resistance increases predictably - typically ≤225Ω at +85°C under ±5V supply. These characteristics are validated per the manufacturer's production test flow for the MAX4052EEE+ variant.
