Analog Devices Inc./Maxim Integrated IH5041CWE

Overview

IH5041CWE from Maxim Integrated is a precision analog switch configured as a single-pole double-throw (SPDT) device with 1.5Ω on-resistance, ±15V supply capability, and −40°C to +85°C operating temperature range; it serves in signal routing for test equipment and data acquisition systems.

For engineers reviewing the IH5041CWE datasheet, IH5041CWE pinout, IH5041CWE application, or IH5041CWE equivalent, key selection criteria include on-resistance matching, break-before-make timing, supply voltage tolerance, and leakage current at elevated temperatures.

Technical Context

The IH5041CWE employs a CMOS-based analog switch architecture with complementary P- and N-channel MOSFETs per path, enabling bidirectional signal flow and rail-to-rail analog operation. It features independent digital control inputs for each switch section and supports dual-supply operation with separate V+ and V− pins.

Break-before-make switching prevents momentary shorting between COM and NO/NC paths during state transitions. The device does not integrate level-shifting circuitry and requires logic-level signals referenced to the same ground as the analog supplies.

FAQ

What is the maximum supply voltage rating for the IH5041CWE?

The IH5041CWE supports analog supply voltages up to ±15V, with absolute maximum ratings of V+ = +16.5V and V− = −16.5V. Operation beyond these limits risks permanent damage. The IH5041CWE is designed for industrial-grade bipolar systems and must be used with properly decoupled ±15V rails to maintain specified on-resistance and leakage performance.

Does the IH5041CWE support break-before-make switching?

Yes, the IH5041CWE guarantees break-before-make operation with a minimum 20ns break interval between disconnecting one path and connecting another. This timing prevents momentary shorts in multiplexed signal paths. The IH5041CWE achieves this through internal control logic that sequences the gate drive of complementary MOSFETs - critical for maintaining signal integrity in precision data acquisition.

What is the typical on-resistance matching between NO and NC paths in the IH5041CWE?

The IH5041CWE provides tightly matched on-resistance between its normally open and normally closed paths, with ΔRON < 0.1Ω typical at ±15V. This matching ensures consistent gain and minimal channel-to-channel error in instrumentation multiplexers. The IH5041CWE achieves this via laser-trimmed process control and symmetrical layout design across both switch paths.

Can the IH5041CWE operate with unipolar supplies?

No, the IH5041CWE requires dual-supply operation with separate V+ and V− pins and cannot function with unipolar supplies. Its internal CMOS switch architecture relies on symmetric voltage rails to bias both P- and N-channel devices correctly. Attempting unipolar operation (e.g., 0V and +15V) will result in incomplete turn-on and excessive leakage. The IH5041CWE is intended exclusively for bipolar analog signal routing.

Is the IH5041CWE pin-compatible with other Maxim analog switches like the IH5040 series?

No, the IH5041CWE is not pin-compatible with the IH5040 series. While both are SPDT analog switches, the IH5041CWE uses a 16-pin SOIC package with dedicated V+, V−, and GND pins, whereas the IH5040 series uses an 8-pin SOIC with different pin assignments and single-supply topology. Layout redesign is required when substituting the IH5041CWE for any IH5040 variant.
