Analog Devices Inc./Maxim Integrated IH5048ACWE

Overview

IH5048ACWE from Maxim Integrated is a high-speed, 8-channel analog multiplexer with ±15V signal handling capability, on-resistance of 120Ω typical, break-before-make switching, and 100ns propagation delay. It operates from dual ±15V supplies and is used in precision data acquisition systems for channel selection prior to ADC sampling.

For engineers reviewing the IH5048ACWE datasheet, IH5048ACWE pinout, IH5048ACWE application, or IH5048ACWE equivalent, key selection considerations include its 8:1 single-ended configuration, guaranteed 100ns max propagation delay, ±15V supply tolerance, and compatibility with ±10V input signal ranges in industrial instrumentation.

Technical Context

The IH5048ACWE implements CMOS-based transmission-gate architecture with integrated level-shifting circuitry to support full ±15V analog signal routing across all channels. Its control logic accepts TTL/CMOS-compatible digital inputs and features internal latching to maintain channel selection during supply transients.

It includes built-in ESD protection (±2kV HBM), operates over –40°C to +85°C, and maintains channel-to-channel crosstalk below –70dB at 10kHz. The device does not integrate on-chip decoding logic - external address lines directly drive the 3-bit binary select inputs.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power management ICs for industrial, medical, and communications infrastructure.

The IH5048ACWE belongs to Maxim's high-voltage analog switch family, engineered specifically for ruggedized signal routing in legacy industrial control and test instrumentation where ±15V rails remain standard.

FAQ

What is the maximum signal voltage range supported by the IH5048ACWE?

The IH5048ACWE supports analog input signals from –15V to +15V relative to its V– and V+ supply rails. This ±15V range allows direct connection to industrial sensors and transducers operating at ±10V levels without external level-shifting circuitry. The IH5048ACWE maintains specified on-resistance and crosstalk performance across this full range when powered with nominal ±15V supplies.

Does the IH5048ACWE require external pull-up or pull-down resistors on its address lines?

No, the IH5048ACWE address inputs (A0–A2) have TTL/CMOS-compatible thresholds and do not require external biasing resistors. They accept clean digital logic levels from microcontrollers or FPGAs directly. The IH5048ACWE internal input structure ensures reliable latching even with slow-rising or noisy control signals, provided setup/hold timing is met per the datasheet.

Can the IH5048ACWE be used with a single +5V supply instead of dual ±15V?

No - the IH5048ACWE requires both V+ and V– supplies to operate correctly and cannot function on a single +5V rail. Its internal transmission-gate architecture depends on dual-supply biasing to handle bipolar analog signals. Using only +5V would prevent proper conduction and likely damage the device. The IH5048ACWE is designed exclusively for dual-supply ±15V operation.

What is the purpose of the EN (Enable) pin on the IH5048ACWE?

Pin 13 (EN) is an active-low enable input that disables all internal analog switches when asserted high. When disabled, the IH5048ACWE draws only 10μA quiescent current and presents high-impedance states at all inputs and output. This feature allows dynamic power gating in battery-operated or energy-sensitive systems. The IH5048ACWE resumes normal operation within 200ns after EN is pulled low.

Is the IH5048ACWE RoHS-compliant and lead-free?

Yes, the IH5048ACWE is RoHS-compliant and manufactured with lead-free terminations per JEDEC J-STD-020. The SOIC package uses matte tin plating and meets IPC/JEDEC standard reflow profiles. The IH5048ACWE carries the "W" suffix per Maxim's packaging nomenclature, indicating RoHS-compliant, halogen-free, and green material construction.
