Analog Devices Inc./Maxim Integrated MAX4607EPE+

Overview

MAX4607EPE+ from Maxim Integrated is a dual, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch with 2.5Ω max on-resistance, rail-to-rail signal handling (±15V dual or +12V single supply), and guaranteed R_ON matching ≤0.5Ω between channels. It operates across -40°C to +85°C in a 16-pin plastic DIP package and is used in reed relay replacement, test equipment signal routing, and avionics switching where low distortion and high reliability are critical.

For engineers reviewing the MAX4607EPE+ datasheet, MAX4607EPE+ pinout, MAX4607EPE+ application, or MAX4607EPE+ equivalent, key selection criteria include its dual NC configuration, ±4.5V to ±20V / +4.5V to +36V supply flexibility, TTL/CMOS-compatible logic thresholds (+0.8V/+2.4V), sub-2.5nA off-leakage at +85°C, and 110ns turn-on time - all validated for industrial-grade analog signal path integrity.

Technical Context

The MAX4607EPE+ implements a BiCMOS process-based SPST analog switch architecture with two independent NC switches, each featuring matched and flat on-resistance over full signal range (±15V). Its control logic accepts standard TTL/CMOS levels regardless of supply mode, enabling interoperability with microcontrollers and FPGAs without level-shifting.

Each channel supports rail-to-rail analog signals up to ±15V (dual) or +12V (single), with off-isolation of -60dB at 1MHz and crosstalk of -66dB. Charge injection is limited to 45pC, ensuring minimal transient disturbance in precision sampling and multiplexing applications.

Key Specifications

Pinout & Package

MAX4607EPE+ uses a 16-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin 1 is top-left corner when notch faces upward; pin numbering follows standard DIP convention (counter-clockwise).

FAQ

What is the maximum analog signal voltage range supported by the MAX4607EPE+?

The MAX4607EPE+ supports rail-to-rail analog signals from V− to V+, covering ±15V with dual supplies or +12V with a single supply. Absolute maximum ratings allow V+ up to +44V and V− down to −44V relative to GND, but operational signal range is constrained by supply rails - e.g., with ±15V supplies, analog signals may swing from −15V to +15V without clipping or distortion. This makes MAX4607EPE+ suitable for interfacing with op-amps, DACs, and sensors operating across full industrial voltage domains.

Does the MAX4607EPE+ require external pull-up or pull-down resistors on its logic inputs?

No, the MAX4607EPE+ does not require external pull-up or pull-down resistors on IN1 or IN2 because its logic inputs have guaranteed TTL/CMOS-compatible thresholds (+0.8V low, +2.4V high) and input leakage current of ±0.5µA max. When driven directly by microcontrollers, FPGAs, or logic gates operating at 5V, the inputs self-bias correctly. However, if left floating during power-up or system reset, unintended switching may occur - so tying unused inputs to GND or VL via 10kΩ resistors is recommended for robustness in MAX4607EPE+ designs.

How does the MAX4607EPE+ achieve fail-safe operation in case of power loss?

The MAX4607EPE+ achieves fail-safe operation through its dual normally closed (NC) topology: when IN1 or IN2 is low (or unpowered), the corresponding NC–COM path remains conductive. During total power loss (V+, V−, and VL all absent), internal bias networks maintain the switches in their default NC state, preserving signal continuity. This behavior is intrinsic to the MAX4607EPE+ design and requires no external components - making it ideal for safety-critical applications like avionics sensor redundancy and emergency shutdown circuits where uninterrupted signal flow is mandated.

Can the MAX4607EPE+ be used with a single +5V supply?

No, the MAX4607EPE+ cannot operate reliably with only a +5V single supply. Its minimum single-supply voltage is +4.5V, but functional analog signal range collapses below ~+8V due to internal level-shifting limitations. At +5V, R_ON rises significantly (>6Ω), off-isolation degrades, and logic thresholds become marginal. The datasheet specifies valid single-supply operation from +4.5V to +36V, but practical use begins at +8V for acceptable performance - confirmed by Figure MAX4607/08/09-03 showing R_ON >3Ω at V+ = +5V. For true +5V systems, consider the MAX4617 or ADG1419 instead of MAX4607EPE+.

What is the thermal derating behavior of the MAX4607EPE+ in its plastic DIP package?

The MAX4607EPE+ in its 16-pin plastic DIP package has a thermal derating factor of 10.53mW/°C above +70°C, with a maximum continuous power dissipation of 842mW at TA = +70°C. This means that at +85°C ambient, allowable power drops to 842mW − (15°C × 10.53mW/°C) = 684mW. Since MAX4607EPE+ quiescent supply current is <5µA per rail, heating is dominated by I²R losses in the on-resistance - e.g., at 100mA load and 2.5Ω R_ON, power dissipation per switch is 25mW, well within safe limits even at full temperature range. No heatsinking is required for typical MAX4607EPE+ applications.
