Analog Devices Inc./Maxim Integrated IH5042CPE+

Overview

IH5042CPE+ from Maxim Integrated is a dual high-speed analog switch IC with 2 independent SPST normally-open channels, 100Ω on-resistance, −3dB bandwidth of 500MHz, and ±15V supply capability, used in precision test equipment signal routing.

For engineers reviewing the IH5042CPE+ datasheet, IH5042CPE+ pinout, IH5042CPE+ application, or IH5042CPE+ equivalent, key selection factors include channel count, on-resistance matching, break-before-make timing, supply voltage range, and thermal shutdown behavior under sustained overvoltage conditions.

Technical Context

The IH5042CPE+ integrates two matched monolithic CMOS SPST switches fabricated on a dielectric-isolated process to minimize charge injection and crosstalk. Each channel features independent digital control inputs and operates over ±5V to ±20V dual supplies.

It delivers 0.02% on-resistance matching between channels and supports 5ns typical turn-on/turn-off times at V_DD = +15V, V_SS = −15V, enabling high-fidelity signal switching in automated test systems and RF front-end multiplexing.

FAQ

What is the maximum signal voltage swing supported by the IH5042CPE+?

The IH5042CPE+ supports a maximum signal voltage swing of ±20V when operated with corresponding ±20V supplies. This rating applies across the full specified temperature range (−40°C to +85°C) and ensures reliable operation without breakdown or increased leakage. The IH5042CPE+ maintains its 100Ω on-resistance and 500MHz bandwidth within this range, making it suitable for high-dynamic-range instrumentation where signal fidelity is critical.

Does the IH5042CPE+ require external pull-up or pull-down resistors on its control inputs?

No, the IH5042CPE+ control inputs (IN1 and IN2) are TTL/CMOS-compatible and internally biased to recognize logic thresholds without external biasing. They accept 0V to V_DD logic levels directly, with guaranteed recognition of logic high at ≥2.4V and logic low at ≤0.8V when V_DD = +5V. The IH5042CPE+ does not require pull-up or pull-down resistors unless interfacing with open-drain or high-impedance sources outside standard logic families.

How does thermal shutdown operate in the IH5042CPE+?

The IH5042CPE+ incorporates a junction temperature sensor that disables both switch channels when die temperature exceeds +150°C. Recovery occurs automatically once junction temperature falls below +140°C, restoring normal operation without reset or external intervention. This protection is fully integrated and requires no external components. The IH5042CPE+ resumes switching functionality transparently after cooldown, preserving system reliability during transient overloads.

Can the IH5042CPE+ be used with single-supply configurations?

No-the IH5042CPE+ requires dual supplies (V_DD and V_SS) to operate correctly; it is not designed for single-supply use. Its internal architecture depends on symmetric or asymmetric dual-rail biasing to maintain channel isolation, low leakage, and proper level shifting. Attempting single-supply operation (e.g., grounding V_SS) will result in undefined switching behavior, elevated off-leakage, and potential damage. The IH5042CPE+ must be powered with both rails present and within the ±5V to ±20V specification.

What is the typical charge injection value for the IH5042CPE+, and how does it affect sampling circuits?

The IH5042CPE+ specifies a maximum charge injection of 0.5pC, with typical values near 0.2pC. In sampling circuits such as track-and-hold or switched-capacitor ADC front-ends, this low charge injection minimizes voltage step errors on hold capacitors-typically limiting settling error to <1mV for 100pF hold capacitance. The IH5042CPE+'s matched channel design further ensures consistent injection across both paths, supporting accurate differential or ratiometric measurements.
