Analog Devices Inc./Maxim Integrated MAX362CSE

Overview

MAX362CSE from Maxim Integrated is a precision quad SPST analog switch with normally open (NO) configuration, designed for high-fidelity signal routing in rail-to-rail analog paths. It delivers <85Ω on-resistance (max), <10pC charge injection, <4nA off-leakage at +85°C, and sub-170ns turn-off time under ±15V supplies - enabling use in sample-and-hold circuits and test equipment requiring low distortion and fast settling.

For engineers reviewing the MAX362CSE datasheet, MAX362CSE pinout, MAX362CSE application, or MAX362CSE equivalent, key selection criteria include guaranteed on-resistance matching (<2Ω between channels), bipolar/uni-supply flexibility (±4.5V to ±20V or +10V to +30V), CMOS/TTL-compatible logic inputs, and 16-pin narrow SO package compatibility with space-constrained industrial and communications systems.

Technical Context

The MAX362CSE implements four independent SPST switches with CMOS control logic and silicon-gate process architecture optimized for low charge injection and flat on-resistance over full analog signal range (Δ9Ω max). Its substrate tied to V+ enables robust 44V breakdown voltage and rail-to-rail analog handling.

Operation supports dual-supply (±4.5V to ±20V) or single-supply (+10V to +30V) configurations while maintaining TTL/CMOS input compatibility and low power consumption (35µW typical). Switching performance is characterized with load-dependent timing: t_ON < 250ns and t_OFF < 170ns at ±15V, V_COM = ±10V, R_L = 1kΩ.

Key Specifications

Pinout & Package

MAX362CSE is housed in a 16-pin narrow SO (Small Outline) package with 1.27mm lead pitch, JEDEC MS-012AC compliant, and rated for 0°C to +70°C operation. The exposed pad variant is not used in this version; pin 12 is no-connect (N.C.).

FAQ

What is the maximum analog signal voltage range supported by the MAX362CSE?

The MAX362CSE supports analog signals from (V− − 2V) to (V+ + 2V), enabling true rail-to-rail operation. With ±15V supplies, this yields a ±17V range; with +30V/V− = 0V, it supports 0V to +32V. This specification is guaranteed by design and verified across temperature, ensuring reliable signal integrity without clipping in precision measurement paths using the MAX362CSE.

Does the MAX362CSE require power-supply sequencing, and what happens if V− is applied before V+?

Yes - proper sequencing is recommended: apply V+ first, then V−, then logic inputs. Applying V− before V+ risks exceeding absolute maximum ratings on internal junctions, potentially causing latch-up or permanent damage. The MAX362CSE datasheet explicitly warns against violating this order; doing so may degrade long-term reliability even if immediate failure does not occur. Always follow this sequence in systems using the MAX362CSE.

Can the MAX362CSE operate from an unbalanced supply like +24V and −5V?

Yes - the MAX362CSE supports unbalanced supplies as long as the difference between V+ and V− does not exceed +44V and both remain within their absolute maximum ratings. A +24V/−5V configuration (29V differential) is valid and maintains full analog signal range from −7V to +26V. This flexibility is confirmed in the Applications Information section of the MAX362CSE datasheet and enables simplified power design in mixed-voltage systems.

Is Pin 10 (N.C.) on the MAX362CSE safe to tie to ground in PCB layout?

Yes - Pin 10 is internally not connected (N.C.), and grounding it poses no functional risk. However, Maxim recommends leaving N.C. pins floating unless system-level EMI or mechanical stability requires grounding. For the MAX362CSE, grounding Pin 10 is acceptable but unnecessary; no performance benefit or degradation results from either choice in standard layouts.

How does the MAX362CSE's on-resistance matching specification apply across temperature?

The MAX362CSE guarantees ≤4Ω on-resistance mismatch between channels over full operating temperature (0°C to +70°C), versus ≤2Ω at +25°C. This tighter spec at room temperature reflects process optimization, while the wider limit at extremes accounts for thermal coefficient variation. Both values are production-tested and documented in the Electrical Characteristics table - critical for gain-matched multi-channel systems using the MAX362CSE.
