Analog Devices Inc./Maxim Integrated MAX4602EPE+

Overview

MAX4602EPE+ from Maxim Integrated is a quad, single-pole single-throw (SPST), normally open (NO) CMOS analog switch with 2.5Ω maximum on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail analog signal handling up to ±10V. It delivers matched on-resistance (≤0.5Ω max between channels) and flat on-resistance (≤0.5Ω max over signal range), making it suitable for precision audio routing and automated test equipment switching paths.

For engineers reviewing the MAX4602EPE+ datasheet, MAX4602EPE+ pinout, MAX4602EPE+ application, or MAX4602EPE+ equivalent, key selection criteria include guaranteed R_ON matching across all four switches, sub-200ns turn-on/turn-off timing, <0.5nA off-leakage at +85°C, and TTL/CMOS-compatible logic thresholds enabling direct interface with +5V microcontrollers in industrial control I/O modules.

Technical Context

The MAX4602EPE+ implements fully independent SPST NO switches controlled by four separate digital inputs, each driving its own transmission gate with no internal logic interdependence. Its architecture uses complementary MOSFET pairs per channel to achieve rail-to-rail conduction and low charge injection (20pC typical).

All switches share common analog supply pins (V+, V−), logic supply (VL), and ground (GND), but feature isolated COM/NO terminals-enabling true 4-channel signal isolation without crosstalk-induced coupling under DC or low-frequency conditions. Off-isolation exceeds −56dB at 1MHz, while on-capacitance remains stable at 140pF (typ).

FAQ

What is the maximum analog signal voltage range supported by the MAX4602EPE+?

The MAX4602EPE+ supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of −44V to +44V across V+ and V−. In standard dual-supply operation (±15V), it reliably handles ±10V signals; in single-supply mode (+12V), it passes 0V to +10V signals without distortion. This range is confirmed in the Electrical Characteristics table under "Input Voltage Range" for VCOM_, VNO_, and VNC_.

Does the MAX4602EPE+ require external pull-up or pull-down resistors on its digital inputs?

No, the MAX4602EPE+ does not require external pull-up or pull-down resistors. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (V_{IN_H} = 2.4V min, V_{IN_L} = 0.8V max) and input leakage current of ±0.5µA max across temperature. Direct connection to FPGA or MCU GPIO pins is fully supported, as verified in the "Logic Input" section of the datasheet's Electrical Characteristics tables.

Can the MAX4602EPE+ operate with V+ = +12V and V− = GND (single supply) while using VL = +5V?

Yes, the MAX4602EPE+ is fully specified for single-supply operation with V+ = +12V, V− = GND, and VL = +5V. The datasheet's "Electrical Characteristics-Single +12V Supply" table explicitly validates R_ON, leakage, timing, and logic compatibility under this configuration. Pin 4 (V−) must be connected to GND, and VL must be decoupled with a 0.1µF capacitor to GND for stable logic interface.

What is the thermal resistance (θ_JA) of the MAX4602EPE+ in its 16-pin plastic DIP package?

The MAX4602EPE+ in the 16-pin plastic DIP package has a junction-to-ambient thermal resistance (θ_JA) of 10.53°C/W, with a maximum continuous power dissipation of 842mW at +70°C ambient. This value is derived from the "Continuous Power Dissipation" specification in the Absolute Maximum Ratings table and is validated for standard JEDEC 2-layer board mounting conditions.

Is the MAX4602EPE+ pin-compatible with other members of the MAX460x family, such as the MAX4601EPE+ or MAX4603EPE+?

Yes, the MAX4602EPE+ is pin-compatible with the MAX4601EPE+ and MAX4603EPE+ in the same 16-pin DIP package. All three share identical pinouts, supply connections, and logic interface-only the internal switch configuration differs (NO-only for MAX4602EPE+, NC-only for MAX4601EPE+, and mixed NO/NC for MAX4603EPE+). This allows drop-in replacement in layouts where switch logic state is software-configurable or externally managed.
