Product details
Overview
IH5045CWE from Maxim Integrated is a high-speed, low-power CMOS analog switch configured as a dual SPDT (single-pole double-throw) with 100 Ω on-resistance, 10 ns switching time, and ±15 V supply capability. It operates in industrial temperature range (–40°C to +85°C) and is used in precision signal routing for data acquisition systems.
For engineers reviewing the IH5045CWE datasheet, IH5045CWE pinout, IH5045CWE application, or IH5045CWE equivalent, key selection considerations include on-resistance matching (max 5 Ω between channels), break-before-make timing, rail-to-rail analog signal handling, and compatibility with ±15 V op-amp front-ends.
Technical Context
The IH5045CWE integrates two independent SPDT switches sharing common control logic and power rails. Each switch exhibits matched on-resistance (<5 Ω channel-to-channel mismatch) and maintains <0.01% THD at 1 kHz with 10 Vpp signal swing.
It uses standard CMOS transmission gate architecture with level-shifted control inputs enabling full rail-to-rail analog signal switching across ±15 V supplies without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Configuration | Dual SPDT - enables independent routing of two analog signals between two destinations each |
| On-Resistance (RON) | 100 Ω max at ±15 V - ensures minimal signal attenuation in precision gain-setting or sensor multiplexing paths |
| Switching Time (tON/tOFF) | 10 ns / 8 ns - supports multiplexing in high-speed data converters sampling up to 50 MSPS |
| Supply Voltage Range | ±15 V - compatible with legacy industrial op-amps and bipolar data acquisition front-ends |
| Channel Matching (ΔRON) | ≤5 Ω - critical for differential signal path integrity and ratiometric measurement accuracy |
| THD @ 1 kHz, 10 Vpp | –100 dB - preserves signal fidelity in audio and instrumentation-grade analog chains |
Pinout & Package
Package: 16-pin SOIC (Wide, 0.300-inch body width). Pin pitch: 1.27 mm. Thermal pad: none. Moisture sensitivity level: MSL 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Analog Inputs/Outputs (NO1, NC1, NO2, NC2) | Normally-open and normally-closed terminals for dual SPDT switching paths |
| 5, 12 | Control Inputs (A1, A2) | Active-high digital inputs selecting NO or NC path per switch |
| 6, 11 | Common Analog Terminals (COM1, COM2) | Signal entry points routed to selected NO/NC terminal per switch |
| 7, 14 | Power Supplies (V+ and V–) | Accept ±15 V rails to support full-swing analog signal handling |
| 8 | GND | Analog ground reference for internal biasing and noise rejection |
| 9, 10, 13, 15, 16 | No Connect | Internally unused; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals spanning V– to V+ without clipping or distortion |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ (Analog Devices) | Lower RON (1.8 Ω), but requires ±15 V only for full performance; 3.3 V logic compatible | Better suited for low-voltage mixed-signal systems where power efficiency is prioritized over legacy rail compatibility | Select ADG1412BRUZ when upgrading from ±15 V designs to 3.3 V/5 V systems with tighter RON tolerance needs |
| TS5A3157DCUR (Texas Instruments) | Single-supply operation (1.65–5.5 V), higher RON (12 Ω), no bipolar supply support | Targeted at portable battery-powered equipment, not industrial ±15 V signal chains | Choose TS5A3157DCUR only for cost-sensitive, low-voltage consumer applications where bipolar supply is absent |
Compared with ADG1412BRUZ and TS5A3157DCUR, the IH5045CWE uniquely supports true ±15 V analog signal routing with matched RON and break-before-make timing-making it irreplaceable in legacy industrial DAQ and test instrumentation requiring full-rail compatibility and channel-matching integrity.

FAQ
What is the maximum analog signal voltage range supported by the IH5045CWE?
The IH5045CWE supports analog signals from V– to V+, with absolute maximum ratings of ±18 V. When operated at ±15 V supplies, it handles rail-to-rail signals up to ±15 V without clipping or distortion-critical for interfacing with legacy op-amps and data acquisition front-ends. The IH5045CWE maintains low THD and matched on-resistance across this full range.
Does the IH5045CWE require external level-shifting for TTL/CMOS control inputs?
No. The IH5045CWE features internally level-shifted control inputs compatible with standard 5 V TTL or CMOS logic levels, even when powered from ±15 V supplies. This eliminates external level translators and simplifies interface design. The IH5045CWE's control pins accept 0 V to 5 V logic signals directly, regardless of analog supply voltage.
Is the IH5045CWE pin-compatible with earlier Maxim analog switches like the DG series?
No. The IH5045CWE uses a 16-pin SOIC package with specific pin assignments for dual SPDT operation and ±15 V supplies, differing from the 14-pin or 16-pin layouts of DG-series switches (e.g., DG403, DG408). Pinouts, supply requirements, and control logic are not interchangeable. System redesign is required when substituting the IH5045CWE for DG-series devices.
What is the typical charge injection value of the IH5045CWE, and why does it matter?
The IH5045CWE specifies typical charge injection of 5 pC. This low value minimizes voltage glitches on high-impedance nodes-such as sample-and-hold capacitors in ADC front-ends or integrator inputs-preventing measurement errors. In precision applications, the IH5045CWE's 5 pC charge injection helps maintain sub-LSB accuracy during fast channel switching.
Can the IH5045CWE be used in audio applications requiring low distortion?
Yes. The IH5045CWE delivers –100 dB THD at 1 kHz with 10 Vpp signal swing, making it suitable for professional audio routing where signal purity is essential. Its matched on-resistance and low charge injection prevent audible artifacts during source switching. For such use cases, the IH5045CWE provides consistent performance across its specified ±15 V operating range.
