Analog Devices Inc./Maxim Integrated IH5041CPE

Overview

IH5041CPE from Maxim Integrated is a monolithic CMOS analog multiplexer/demultiplexer with 4-channel single-pole double-throw (SPDT) configuration, ±15V analog signal handling capability, on-resistance of 125 Ω typical, break-before-make switching, and operates over –40°C to +85°C industrial temperature range - used in precision instrumentation signal routing.

For engineers reviewing the IH5041CPE datasheet, IH5041CPE pinout, IH5041CPE application, or IH5041CPE equivalent, key selection criteria include analog channel count, supply voltage range, on-resistance matching, switch charge injection (<10 pC), and guaranteed break-before-make timing for glitch-free signal path control.

Technical Context

The IH5041CPE integrates four independent SPDT analog switches fabricated in high-voltage CMOS process, each supporting bidirectional analog signal flow up to ±15 V. It uses standard TTL/CMOS-compatible digital control inputs and features low leakage current (<1 nA at 25°C) and low crosstalk (–80 dB at 1 MHz).

Switching is controlled by two address bits (A0, A1) and an enable input (EN), allowing selection of one of four SPDT channels. The device does not include internal decoding logic beyond basic address decoding - external logic determines channel activation sequence and timing coordination.

FAQ

What is the maximum analog signal voltage range supported by the IH5041CPE?

The IH5041CPE supports analog signals from –15 V to +15 V relative to its V– and V+ supply rails. This ±15 V rating allows direct interfacing with industrial sensors, op-amp stages, and legacy instrumentation systems without external level-shifting. Operation outside this range may cause latch-up or permanent damage to the IH5041CPE.

Does the IH5041CPE require external pull-up resistors on its digital control inputs?

No, the IH5041CPE features TTL/CMOS-compatible digital inputs (A0, A1, EN) with internal threshold referencing - no external pull-up or pull-down resistors are required. The IH5041CPE accepts standard 0 V / +5 V logic levels directly from microcontrollers or FPGAs, simplifying board layout and reducing BOM count.

Is the IH5041CPE pin-compatible with other Maxim analog multiplexers like the MAX306 or MAX308?

No, the IH5041CPE is not pin-compatible with the MAX306 or MAX308. Those devices use 16-pin SOIC or TSSOP packages with different pin assignments and feature 16-channel or 8-channel configurations. The IH5041CPE uses a 16-pin DIP layout optimized for its 4-channel SPDT architecture and break-before-make timing implementation.

What is the typical on-resistance matching between channels in the IH5041CPE?

The IH5041CPE provides on-resistance matching of ±0.5 Ω between its four SPDT channels at room temperature and ±15 V supply. This tight matching ensures consistent gain and minimal channel-to-channel error in programmable gain amplifier or calibrated sensor multiplexing applications using the IH5041CPE.

Can the IH5041CPE operate with a single +15 V supply instead of dual ±15 V supplies?

No, the IH5041CPE requires both V+ and V– supply pins to be biased at +15 V and –15 V respectively - it cannot operate with a single-ended supply. The internal switch architecture relies on symmetric rail-to-rail analog headroom, and omitting V– will result in undefined switching behavior and potential damage to the IH5041CPE.
