Analog Devices Inc./Maxim Integrated MAX301ESE+T

Overview

The MAX301ESE+T from Maxim Integrated is a precision dual SPST analog switch optimized for high-accuracy signal routing in bipolar or single-supply systems. It features 35Ω max on-resistance, <2Ω channel-to-channel matching, <15pC charge injection, rail-to-rail analog signal handling (±15V), and operates from ±4.5V to ±20V or +10V to +30V supplies - enabling use in military radios, test equipment, and battery-operated guidance systems.

For engineers reviewing the MAX301ESE+T datasheet, MAX301ESE+T pinout, MAX301ESE+T application, or MAX301ESE+T equivalent, key selection criteria include guaranteed on-resistance flatness (Δ5Ω max), sub-100ns turn-off time, -40°C to +85°C industrial temperature rating, SO-16 narrow package, and compatibility with TTL/CMOS logic inputs at VL = +5V.

Technical Context

The MAX301ESE+T implements two independent normally-open (NO) analog switches fabricated using Maxim's silicon-gate process. Each switch supports bidirectional analog signal flow between COM and NO terminals, with CMOS/TTL-compatible digital control inputs (IN1/IN2) referenced to VL = +5V and isolated supply rails (V+, V-, GND).

Its architecture guarantees matched on-resistance (<2Ω) and flat R_ON over full signal range (Δ5Ω max), low leakage (<6nA at +85°C), and minimal charge injection (15pC typ), making it suitable for sample-and-hold circuits and precision multiplexing where signal integrity and channel-to-channel consistency are critical.

Key Specifications

Pinout & Package

MAX301ESE+T is housed in a 16-pin narrow SOIC (S16-2) package with exposed pad not electrically connected. Pin functions are validated per Maxim's official pin description table for the MAX301 family.

FAQ

What is the maximum analog signal voltage range supported by the MAX301ESE+T?

The MAX301ESE+T supports analog signals from V− to V+, with absolute maximum ratings of ±44V on V+ and V−. When operated with ±15V supplies, it handles rail-to-rail signals from −15V to +15V. This range remains valid across its full −40°C to +85°C operating temperature, confirmed in the Electrical Characteristics table under "Analog-Signal Range" (VANA). The MAX301ESE+T maintains low on-resistance flatness (Δ5Ω max) across this entire span.

Does the MAX301ESE+T require a separate logic supply, and what voltage is needed?

Yes, the MAX301ESE+T requires a dedicated logic supply (VL) pin. For TTL-compatible operation, VL must be +5V. If VL is tied to V+ or another voltage, the device operates with CMOS-level thresholds instead. This requirement is explicitly defined in the "Logic Inputs" section and verified in the Absolute Maximum Ratings table, where VL is specified as (GND−0.3V) to (V+) +0.3V. The MAX301ESE+T draws only 0.01µA typical logic supply current.

Can the MAX301ESE+T be used with a single positive supply only?

Yes, the MAX301ESE+T supports single-supply operation from +10V to +30V. In this configuration, V− is connected to GND (pin 13), V+ (pin 11) receives the positive rail, and analog signals swing from 0V to V+. The datasheet confirms rail-to-rail capability under this condition, and the Typical Operating Characteristics include curves for V− = 0V. The MAX301ESE+T retains all key specs - including <35Ω R_ON, <15pC charge injection, and <100ns t_OFF - in single-supply mode.

What is the guaranteed on-resistance matching between the two switches in the MAX301ESE+T?

The MAX301ESE+T guarantees on-resistance matching of ≤2Ω between its two SPST switches at +25°C, and ≤3Ω across the full −40°C to +85°C temperature range. This specification is explicitly listed in the Electrical Characteristics table under "On-Resistance Match Between Channels" and applies under standard test conditions (I_S = −10mA, V_COM = ±10V). The MAX301ESE+T achieves this via matched transistor design in Maxim's silicon-gate process.

Is the MAX301ESE+T pin-compatible with other devices in the MAX301/MAX303/MAX305 family?

No - the MAX301ESE+T is not pin-compatible with MAX303ESE+T or MAX305ESE+T. Although all three share the same 16-pin SOIC package, their pinouts differ significantly: MAX301 uses COM1/COM2 on pins 1/8 and NO1/NO2 on pins 9/16, while MAX303 adds NC/COM3/COM4 pins and MAX305 substitutes NO3/NO4. This is clearly shown in the "Pin Configurations" diagrams and confirmed in the "Pin Descriptions" table. The MAX301ESE+T pinout is unique to the MAX301 variant.
