Product details
Overview
IH5043CWE+ from Maxim Integrated is a high-speed, low-power, monolithic CMOS analog switch configured as a dual SPDT (single-pole double-throw) switch 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 IH5043CWE+ datasheet, IH5043CWE+ pinout, IH5043CWE+ application, or IH5043CWE+ equivalent, key selection criteria include on-resistance matching (max 5 Ω between channels), break-before-make timing, rail-to-rail analog signal handling, and compatibility with ±5 V to ±15 V dual supplies.
Technical Context
The IH5043CWE+ integrates two independent SPDT switches on a single die using enhanced CMOS process technology, enabling bidirectional analog/digital signal switching without polarity constraints. Each switch exhibits matched on-resistance (<5 Ω channel-to-channel mismatch) and low charge injection (10 pC typical), critical for sample-and-hold and multiplexer applications.
It features TTL/CMOS-compatible control inputs with 0.8 V/2.0 V logic thresholds, operates from dual ±5 V to ±15 V supplies, and maintains <0.01% THD at 1 kHz with 10 Vpp signal - confirming suitability for audio and instrumentation-grade signal paths.
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 and sensor interface paths |
| Switching Time (tON/tOFF) | 10 ns / 8 ns - supports multiplexing in high-speed data acquisition up to 10 MSPS effective rate |
| Charge Injection | 10 pC typical - reduces droop error in sample-and-hold circuits requiring sub-12-bit settling |
| Supply Voltage Range | ±5 V to ±15 V - allows direct interfacing with legacy op-amp rails and industrial sensor excitation sources |
| THD @ 1 kHz, 10 Vpp | 0.01% - meets audio line-level and medical front-end signal integrity requirements |
Pinout & Package
Package: 16-pin SOIC Wide (SOIC-W), 7.5 mm body width, 1.27 mm pitch - compatible with standard automated PCB assembly and thermal relief design rules for 1.5 W dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Analog I/O terminals (CH1A, CH1B, CH2A, CH2B) | Four bidirectional analog ports - each pair forms one SPDT switch's throw terminals |
| 5, 10 | Common terminals (COM1, COM2) | Input/output nodes routed to selected throw via internal MOSFETs - must be AC-coupled or DC-biased within supply rails |
| 6, 9 | Control inputs (IN1, IN2) | TTL/CMOS-compatible digital select lines - low = connect COM to A, high = connect COM to B |
| 7, 14 | V+ and V− | Dual supply pins - define analog signal swing range; no internal regulation or sequencing required |
| 8, 15 | GND | Analog ground reference - requires low-impedance star connection to minimize crosstalk between channels |
| 16 | NC | No-connect - must remain unconnected per datasheet; not internally tied or tested |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input signals spanning full V− to V+ range - eliminates level-shifting in ±12 V sensor interfaces |
| Matched on-resistance (ΔRON) | ≤5 Ω between CH1 and CH2 - enables precise ratio-metric measurements in dual-channel thermocouple or RTD scanners |
| Break-before-make switching | Guaranteed 5 ns minimum break interval - prevents momentary shorting during channel transitions in multiplexed ADC front-ends |
| Low off-leakage current | 1 nA max at 25°C - preserves voltage integrity across high-Z sample capacitors >10 nF |
Applications
| Industrial Data Acquisition | Automated Test Equipment (ATE) |

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 (2.4 Ω), but only supports ±5 V to ±15 V with derated performance above ±12 V; higher charge injection (15 pC) | Better for low-RON precision gain-switching; less suitable for ±15 V sensor excitation paths | Choose ADG1412BRUZ when RON matching dominates over supply headroom and charge injection |
| TS5A23157DGSR (Texas Instruments) | Single-supply only (1.65 V to 5.5 V); 0.9 Ω RON; no dual ±V support; smaller 10-pin VSSOP package | Limited to battery-powered or low-voltage logic-controlled systems; incompatible with industrial ±12 V/±15 V rails | Choose TS5A23157DGSR only for portable, single-supply 3.3 V systems where ultra-low RON is critical |
Compared with ADG1412BRUZ and TS5A23157DGSR, the IH5043CWE+ uniquely balances ±15 V operation, 100 Ω RON stability across full supply range, and 10 ns speed - making it the only option among the three supporting simultaneous high-voltage rail integrity and fast multiplexing in industrial DAQ.

FAQ
What is the maximum supply voltage rating for the IH5043CWE+?
The IH5043CWE+ supports dual supplies from ±5 V up to ±15 V. Operation at ±15 V is fully specified - including on-resistance, switching time, and THD - and does not require derating. Exceeding ±15 V risks permanent damage to the internal MOSFET structures. The IH5043CWE+ must be operated within this absolute maximum rating to ensure reliability and parameter compliance.
Does the IH5043CWE+ support break-before-make switching?
Yes, the IH5043CWE+ guarantees break-before-make operation with a minimum 5 ns break interval between channel disconnect and reconnect. This timing is process-verified and specified across temperature and supply voltage. Break-before-make prevents momentary shorts in multiplexed ADC front-ends and ensures safe reconfiguration in IH5043CWE+ -based signal routing networks.
Can the IH5043CWE+ handle rail-to-rail analog signals?
Yes, the IH5043CWE+ supports rail-to-rail analog signal switching - meaning input signals may extend from V− to V+ without clipping or distortion. This capability is maintained across the full ±5 V to ±15 V supply range and is verified by THD and leakage specifications. Rail-to-rail operation makes the IH5043CWE+ suitable for direct interfacing with op-amps and sensors operating at full supply rails.
What is the typical charge injection of the IH5043CWE+ and why does it matter?
The IH5043CWE+ has a typical charge injection of 10 pC. This parameter directly impacts voltage error in sample-and-hold circuits and capacitive multiplexer nodes. At 10 pC, the IH5043CWE+ limits droop-induced offset to <100 µV on a 100 pF hold capacitor - critical for 12-bit+ accuracy in IH5043CWE+ -based data acquisition systems.
Is the IH5043CWE+ pin-compatible with other Maxim analog switches like the IH5042?
No, the IH5043CWE+ is not pin-compatible with the IH5042. The IH5042 is a quad SPST switch in 16-pin SOIC, while the IH5043CWE+ is a dual SPDT device with different pin assignments - notably separate COM and throw terminals versus shared I/O. Pin mapping, control logic, and internal topology differ; PCB layout redesign is required when substituting IH5043CWE+ for IH5042 or vice versa.
