Analog Devices Inc./Maxim Integrated MAX4622CPE

Overview

MAX4622CPE from Maxim Integrated is a dual, single-pole/double-throw (SPDT) analog switch with two normally closed (NC) and two normally open (NO) poles, 5Ω maximum on-resistance, guaranteed 0.5Ω max R_ON match between channels, and rail-to-rail analog signal handling from ±18V bipolar or +4.5V to +36V single supply - used in precision audio-signal routing and test equipment switching paths.

For engineers reviewing the MAX4622CPE datasheet, MAX4622CPE pinout, MAX4622CPE application, or MAX4622CPE equivalent, key selection criteria include break-before-make timing assurance, <5nA off-leakage at +85°C, sub-250ns turn-on time, and compatibility with TTL/CMOS logic levels across wide supply ranges.

Technical Context

The MAX4622CPE implements monolithic CMOS analog switch architecture with integrated protection diodes and guaranteed break-before-make operation for both SPDT sections - ensuring no signal shorting during state transitions. Its R_ON flatness remains within ±0.5Ω over full analog signal range (±10V), enabling low-distortion signal routing in data-acquisition front-ends.

It supports dual-supply operation (±4.5V to ±18V) and single-supply mode (+4.5V to +36V), with logic inputs compatible to TTL/CMOS thresholds (V_INL ≤ 0.8V, V_INH ≥ 2.4V) and independent VL pin for logic-level translation - critical for mixed-voltage system interfacing.

FAQ

What is the maximum analog signal voltage range supported by the MAX4622CPE?

The MAX4622CPE supports analog signals from V− to V+, enabling rail-to-rail operation. With bipolar supplies of ±15V, it handles ±15V signals; with single +36V supply and GND, it routes 0V to +36V signals. Absolute maximum ratings allow V+ to V− differential up to 44V, but signal range remains bounded by the applied supply rails. This capability is confirmed in the Electrical Characteristics tables and Typical Operating Characteristics plots for both dual- and single-supply configurations.

Does the MAX4622CPE require external pull-up or pull-down resistors on its logic inputs?

No, the MAX4622CPE does not require external pull-up or pull-down resistors on IN1 or IN2. Its logic inputs are CMOS/TTL-compatible with guaranteed V_INL ≤ 0.8V and V_INH ≥ 2.4V, and input leakage is specified at ±0.5µA max. The device operates correctly with direct connection to microcontroller GPIOs or logic gates. This behavior is verified in the Electrical Characteristics table under "Logic Input Voltage Low/High" and "Input Current" parameters.

Is the MAX4622CPE pin-compatible with the DG403 analog switch?

Yes, the MAX4622CPE is explicitly documented as a pin-compatible replacement for the DG403. The datasheet states: "The MAX4621/MAX4622/MAX4623 are pin-compatible replacements for the DG401/DG403/DG405, respectively." Pin mapping, package outline (16-pin DIP), and functional diagram alignment confirm identical pin functions - including COM, NO, NC, V+, V−, VL, GND, and logic inputs - enabling drop-in substitution without layout changes.

What is the guaranteed break-before-make time specification for the MAX4622CPE?

The MAX4622CPE guarantees break-before-make operation, with a typical break-before-make delay (t_D) of 90ns and maximum of 200ns under dual-supply conditions (V+ = +15V, V− = −15V). This parameter is explicitly listed in the "Switch Dynamic Characteristics" table and applies to both SPDT sections. The guarantee ensures no overlap between NC and NO conduction, preventing momentary shorts - a key differentiator from non-BBM switches like the ADG403.

Can the MAX4622CPE operate with mismatched positive and negative supply voltages, such as +12V and −5V?

Yes, the MAX4622CPE can operate with asymmetric bipolar supplies, provided each rail stays within its absolute maximum rating: V+ to GND ≤ +44V, V− to GND ≥ −44V, and V+ to V− ≤ +44V. For example, +12V and −5V yields a 17V differential - well within limits. However, the routable analog signal range becomes V− to V+, i.e., −5V to +12V. This flexibility is confirmed in the "Operation with Supply Voltages Other Than ±15V" section and Absolute Maximum Ratings table.
