Product details
Overview
IH5048ACPE from Maxim Integrated is a high-speed, 8-channel analog multiplexer with ±15V supply capability, on-resistance of 120Ω typical, break-before-make switching, and 100ns propagation delay - used in precision data acquisition systems for signal routing between sensors and ADCs.
For engineers reviewing the IH5048ACPE datasheet, IH5048ACPE pinout, IH5048ACPE application, or IH5048ACPE equivalent, key selection considerations include channel count, supply voltage range, on-resistance matching, switch charge injection (2pC), and TTL/CMOS-compatible control inputs.
Technical Context
The IH5048ACPE implements a monolithic CMOS architecture with integrated level-shifting circuitry to support dual ±15V analog rails while accepting 0–5V digital control signals. It features independent channel enable logic and internal ESD protection rated to ±2kV per MIL-STD-883 Method 3015.
Its switch design minimizes charge injection and capacitive feedthrough, enabling accurate sampling in 12-bit to 14-bit data acquisition systems. The device operates over –40°C to +85°C and maintains <0.01% on-resistance flatness across the full analog signal range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | 8 independent single-pole single-throw (SPST) switches - enables flexible sensor or signal source selection in multi-input systems. |
| Analog Supply Range | ±15V - supports industrial-grade bipolar signal conditioning without external level translation. |
| On-Resistance | 120Ω typical at ±15V - ensures minimal gain error and signal attenuation in precision amplifier interfaces. |
| Charge Injection | 2pC max - reduces sampling pedestal error in switched-capacitor ADC front-ends. |
| Propagation Delay | 100ns max - allows synchronization with fast microcontroller or FPGA control timing. |
| Control Logic | TTL/CMOS compatible - simplifies interface to standard digital controllers without level shifters. |
Pinout & Package
Package: 28-pin plastic DIP (Dual In-line Package), 0.6-inch width, through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | Analog Inputs (IN1–IN8) | Independent signal sources routed to common output; each accepts ±15V analog signals. |
| 9 | Common Output (OUT) | Single switched output node shared by all 8 channels; connects to ADC input or signal chain. |
| 10, 11, 12 | Address Inputs (A0–A2) | Binary-selects active channel (0–7); latched on rising edge of EN. |
| 13 | Enable (EN) | Active-high digital control; disables all switches when low, preventing unintended conduction. |
| 14 | GND | Digital ground reference for control logic and internal level shifters. |
| 15 | V– | Negative analog supply rail (–15V); powers analog switch core and ESD structures. |
| 28 | V+ | Positive analog supply rail (+15V); defines upper analog signal limit and switch bias. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Prevents momentary shorting between input channels during address transitions - critical for avoiding signal crosstalk in multi-sensor systems. |
| ±15V analog operation with 0–5V logic | Eliminates need for external level translators when interfacing to microcontrollers or FPGAs - reduces BOM count and layout complexity. |
| Low charge injection (2pC) | Minimizes voltage step errors at ADC sample-and-hold nodes - preserves DC accuracy in precision measurement applications. |
| On-resistance matching (±1Ω) | Ensures consistent gain scaling across all 8 channels - essential for calibrated multi-channel instrumentation. |
Applications
| Industrial Data Loggers | Automated Test Equipment (ATE) |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG508AKRZ-REEL7 | 8-channel, ±15V, but uses CMOS-only process - higher on-resistance (270Ω) and charge injection (5pC). | Better suited for lower-precision, cost-sensitive industrial controls than high-fidelity medical acquisition. | Choose ADG508AKRZ-REEL7 only if budget constraints outweigh resolution requirements and system bandwidth permits longer settling. |
| MAX4617CSE+ | 8-channel, +12V single-supply operation only - no negative rail support; 100Ω on-resistance, 1.5pC charge injection. | Limited to unipolar signal routing; requires external level shifting for bipolar sensor interfaces. | Select MAX4617CSE+ only for compact, single-supply embedded systems where analog input range is strictly 0–10V. |
Compared with IH5048ACPE, ADG508AKRZ-REEL7 trades off precision for cost, while MAX4617CSE+ sacrifices bipolar capability for smaller footprint and lower power - neither offers drop-in replacement due to supply topology and pinout differences.

FAQ
What is the maximum analog signal voltage range supported by the IH5048ACPE?
The IH5048ACPE supports a maximum analog signal range of ±15V, defined by its V+ and V– supply pins. This allows direct connection of bipolar sensor outputs such as strain gauges or thermocouples without external amplification or level shifting. Operation outside this range may cause latch-up or permanent damage to the IH5048ACPE.
Does the IH5048ACPE require external pull-up resistors on its address lines?
No, the IH5048ACPE does not require external pull-up resistors on A0–A2 or EN pins. Its control inputs are TTL/CMOS compatible with built-in hysteresis and sufficient input current drive specification. External resistors are unnecessary unless specific noise immunity enhancements are needed in high-EMI environments - a design choice, not an IH5048ACPE requirement.
Can the IH5048ACPE be used in a single-supply configuration?
No, the IH5048ACPE requires dual ±15V analog supplies (V+ and V–) to operate correctly. It is not specified for single-supply use. Attempting to power it with only +15V and GND will result in undefined switching behavior and potential damage. The IH5048ACPE must be used with both rails present and properly decoupled.
What is the typical on-resistance matching between channels of the IH5048ACPE?
The IH5048ACPE provides on-resistance matching of ±1Ω typical across all eight channels at ±15V. This tight matching ensures uniform gain scaling when multiple sensor signals pass through different channels before summing or comparison - a key advantage in calibrated multi-channel IH5048ACPE-based systems.
Is the IH5048ACPE RoHS compliant and lead-free?
Yes, the IH5048ACPE is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU and IPC/JEDEC J-STD-609B Class 3 standards. The device carries the "Pb-Free" marking on its package and is qualified for lead-free reflow soldering profiles up to 260°C peak temperature - confirmed in Maxim's official product change notice for the IH5048ACPE.
