Analog Devices Inc./Maxim Integrated MAX362EPE

Overview

MAX362EPE from Maxim Integrated is a precision quad SPST analog switch with normally open (NO) configuration, designed for rail-to-rail signal routing in high-fidelity sample-and-hold and test equipment circuits. It delivers <85Ω on-resistance (max), <10pC charge injection, <4nA off-leakage at +85°C, and operates from ±4.5V to ±20V or +10V to +30V supplies.

For engineers reviewing the MAX362EPE datasheet, MAX362EPE pinout, MAX362EPE application, or MAX362EPE equivalent, this device is selected for low-distortion analog switching where channel matching (<2Ω R_ON match), flat on-resistance (∆9Ω max), and ESD robustness (>2000V) are critical in guidance systems, PBX interfaces, and battery-operated instrumentation.

Technical Context

The MAX362EPE implements four independent CMOS-controlled SPST switches fabricated in Maxim's 44V silicon-gate process. Its bipolar or single-supply operation preserves TTL/CMOS logic compatibility while enabling full rail-to-rail analog signal handling up to ±15.5V.

Each switch features matched on-resistance across channels and flat R_ON versus signal voltage-guaranteed only under bipolar supply conditions. Charge injection is tightly controlled (<10pC) to minimize sampling error in precision acquisition paths.

FAQ

What is the maximum analog signal voltage range supported by the MAX362EPE?

The MAX362EPE supports rail-to-rail analog signals up to ±15.5V when operated with ±16.5V supplies. This is enabled by its 44V breakdown voltage and bipolar supply architecture. Under single-supply conditions (+12V), the analog range is 0V to +12V. The MAX362EPE datasheet specifies these limits in the Absolute Maximum Ratings and Electrical Characteristics tables, confirming operation across the full range without distortion or latch-up.

Does the MAX362EPE require external protection diodes for overvoltage tolerance?

No, the MAX362EPE does not require external protection diodes under normal operating conditions. Its absolute maximum ratings allow input voltages from (V− − 2V) to (V+ + 2V), and it is rated for >2000V ESD per Method 3015.7. However, if supply sequencing cannot be guaranteed (e.g., V− powered before V+), Maxim recommends adding two series diodes per supply rail-as shown in Figure 6 of the MAX362EPE datasheet-to prevent substrate forward-biasing and potential damage.

Can the MAX362EPE operate with unbalanced supplies such as +24V and −5V?

Yes, the MAX362EPE can operate with unbalanced supplies like +24V and −5V, provided the difference between V+ and V− does not exceed +44V and both remain within their absolute maximum ratings. The MAX362EPE datasheet explicitly states this capability in the Applications Information section. In such configurations, the analog signal range is constrained by the lesser of the positive or negative headroom, and R_ON flatness guarantees apply only under bipolar-symmetric conditions.

Is the MAX362EPE pin-compatible with the MAX361EPE?

Yes, the MAX362EPE is pin-compatible with the MAX361EPE: both share identical 16-pin DIP pinouts, supply connections, logic inputs, and COM/NO or COM/NC terminal assignments. The only functional difference is that MAX361EPE uses normally closed (NC) switches while MAX362EPE uses normally open (NO) switches. No PCB changes are required when substituting between them, though logic polarity and default signal path behavior differ.

What is the guaranteed on-resistance match between channels for the MAX362EPE at −40°C to +85°C?

The MAX362EPE guarantees on-resistance match of ≤4Ω between channels across the full −40°C to +85°C operating temperature range under bipolar supply conditions. At +25°C, the match is tighter: ≤2Ω. This specification is explicitly listed in the "On Resistance Match Between Channels" row of the Electrical Characteristics table for dual-supply operation and is validated per Maxim's production test flow for the MAX362EPE grade.
