Analog Devices Inc./Maxim Integrated MAX365ESE

Overview

MAX365ESE 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), <2Ω channel-to-channel matching, <10pC charge injection, <4nA off-leakage at +85°C, and 250ns turn-on time - enabling use in sample-and-hold circuits and test equipment requiring low distortion and minimal signal corruption.

For engineers reviewing the MAX365ESE datasheet, MAX365ESE pinout, MAX365ESE application, or MAX365ESE equivalent, key selection criteria include bipolar supply operation (±4.5V to ±20V), CMOS/TTL logic compatibility, guaranteed flat on-resistance over full analog range (∆9Ω max), and ESD robustness (>2000V per Method 3015.7).

Technical Context

The MAX365ESE implements four independent SPST switches with NO topology, each controlled by a dedicated CMOS/TTL-compatible logic input. Its silicon-gate architecture ensures matched on-resistance across channels and minimal variation with analog signal voltage (±4.5V to ±20V dual supply or +10V to +30V single supply).

Charge injection is tightly controlled (<10pC typ) to preserve accuracy in sampling applications, while off-isolation exceeds 60dB and crosstalk remains below -100dB - critical for multiplexed signal integrity in communication systems and guidance electronics.

FAQ

What is the maximum supply voltage rating for MAX365ESE?

The MAX365ESE has an absolute maximum V+ rating of +44V and V− rating of −44V, with recommended operating range of ±4.5V to ±20V for bipolar supplies or +10V to +30V for single-ended supplies. Exceeding these limits risks permanent damage, and proper sequencing (V+ first, then VL/V−) is required to avoid latch-up.

Does MAX365ESE support TTL-level logic inputs?

Yes, MAX365ESE supports TTL-level inputs when VL is tied to +5V - its logic thresholds are specified at VINH = 2.4V (min) and VINL = 0.8V (max). With VL = V+, it operates with standard CMOS thresholds. Input current remains below ±0.5µA across temperature, minimizing loading on driving logic.

What is the guaranteed on-resistance flatness specification for MAX365ESE?

The MAX365ESE guarantees on-resistance flatness of ∆9Ω maximum over the full analog signal range (V− to V+) when operated with bipolar supplies. This specification is tested per channel at VCOM = ±5V, ±10V, and ±15V with V+ = 15V and V− = −15V, ensuring consistent signal attenuation regardless of input voltage level.

Can MAX365ESE be used in single-supply configurations?

Yes, MAX365ESE operates with single supplies from +10V to +30V. In this mode, V− must be connected to GND, and VL should be set to +5V for TTL compatibility or to V+ for CMOS logic levels. The analog signal range becomes 0V to V+, and on-resistance increases slightly versus bipolar operation - e.g., 100Ω typical at +12V.

Is the exposed pad on the MAX365ESE SO package electrically connected?

Yes, the exposed pad on the MAX365ESE narrow SO package is internally connected to V+ and must be soldered to a V+ copper pour on the PCB for thermal and electrical performance. Leaving it floating degrades ESD immunity and thermal dissipation - per Maxim's datasheet, this connection is mandatory for reliable operation.
