Product details
Overview
IH5050CWE from Maxim Integrated is a high-speed, dual-channel analog switch with 50 Ω on-resistance, ±15 V supply capability, and 200 MHz bandwidth-designed for precision signal routing in test instrumentation and automated test equipment (ATE) systems.
For engineers reviewing the IH5050CWE datasheet, IH5050CWE pinout, IH5050CWE application, or IH5050CWE equivalent, key selection considerations include its matched on-resistance (<1 Ω tracking), low charge injection (0.5 pC), and TTL/CMOS-compatible control inputs enabling fast, low-distortion switching in RF and video signal paths.
Technical Context
The IH5050CWE integrates two independent SPST analog switches in a single SOIC-16 package, each featuring complementary MOSFET architecture with matched P- and N-channel devices to minimize distortion and ensure symmetrical conduction. Its 50 Ω on-resistance remains stable across ±15 V analog signal swing and full temperature range (–40°C to +85°C).
Switching is controlled by active-high digital inputs compatible with 3 V to 5 V logic families. Charge injection and off-isolation (–65 dB at 1 MHz) are specified under 0 V to ±10 V signal conditions, supporting bidirectional AC/DC signal routing without polarity constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 50 Ω max at ±15 V supplies - ensures minimal insertion loss in 50 Ω system impedance matching |
| On-resistance match | ≤1 Ω between channels - critical for differential signal integrity and channel-to-channel timing alignment |
| Bandwidth | 200 MHz (–3 dB) - supports video, RF, and high-speed data routing up to SDI and USB 1.1 rates |
| Charge injection | 0.5 pC typical - reduces transient glitches and settling error in sample-and-hold and multiplexed ADC front-ends |
| Off-isolation | –65 dB at 1 MHz - prevents crosstalk between active and inactive signal paths in dense ATE backplanes |
| Supply voltage | ±15 V - enables full-swing operation with bipolar signals up to ±10 V without clipping |
Pinout & Package
Package: 16-pin SOIC (SOIC-W, 7.5 mm width), surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Channel 1 input/output | Bidirectional analog path; symmetric I/O with no intrinsic directionality |
| 3 | Channel 1 enable | Active-high TTL/CMOS-compatible control; drives switch ON when ≥2.0 V |
| 4, 5 | Channel 2 input/output | Independent second path; electrically isolated from Channel 1 |
| 6 | Channel 2 enable | Separate digital control; allows asynchronous switching of dual channels |
| 7, 14 | V– / V+ | Analog supply pins; require ±15 V for full dynamic range and on-resistance spec compliance |
| 8 | GND | Analog ground reference; must be low-impedance and separated from digital ground |
| 16 | VDD | Digital supply (3 V to 5 V); powers internal level-shifting logic for control interface |
Key Features
| Feature | Design Value |
|---|---|
| Matched 50 Ω on-resistance | Enables consistent impedance termination across both channels for balanced RF and video distribution |
| Low charge injection (0.5 pC) | Minimizes voltage step errors in precision sampling circuits and multiplexed sensor interfaces |
| ±15 V analog supply support | Permits direct switching of industrial-level bipolar signals without external level-shifting circuitry |
| TTL/CMOS-compatible enables | Eliminates need for dedicated logic translators when interfacing with FPGA or microcontroller GPIOs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single SPDT, 50 Ω RON, but only ±15 V analog supply; no dual-channel integration | Requires two devices for dual-path routing; higher board area and control complexity | Select if needing SPDT topology with tighter RON flatness over voltage (0.1 Ω variation vs. IH5050CWE's 1 Ω match) |
| TS5A23157DRCR | Single SPDT, 5 V only supply, 0.9 Ω RON, 200 MHz BW - lacks bipolar supply and precision matching | Suitable for low-voltage consumer audio/video; not rated for ±10 V signal swing or ATE-grade isolation | Choose for cost-sensitive, single-ended 3.3 V systems where ±15 V operation and channel matching are unnecessary |
Compared with ADG1419BRUZ and TS5A23157DRCR, the IH5050CWE uniquely delivers dual SPST functionality with matched 50 Ω on-resistance, ±15 V analog support, and sub-pC charge injection-making it the only option qualified for high-fidelity, bipolar-signal multiplexing in production ATE and RF calibration hardware.

FAQ
What is the maximum analog signal voltage range supported by the IH5050CWE?
The IH5050CWE supports analog signals from –10 V to +10 V when operated with ±15 V supplies. This full-swing capability is enabled by its complementary MOSFET architecture and is specified across the entire industrial temperature range (–40°C to +85°C). The IH5050CWE maintains 50 Ω on-resistance and low distortion within this range, making it suitable for bipolar instrumentation signals without external level-shifting circuitry.
Does the IH5050CWE require separate digital and analog ground connections?
Yes-the IH5050CWE has dedicated GND (Pin 8) for analog reference and VDD (Pin 16) for digital logic supply. While the datasheet permits connecting them at a single low-impedance point near the device, best practice is to maintain separate ground planes joined only at the power entry point to minimize digital noise coupling into sensitive analog paths. This layout approach preserves the IH5050CWE's –65 dB off-isolation and low charge injection performance.
Can the IH5050CWE be used in AC-coupled video applications?
Yes-the IH5050CWE is commonly deployed in AC-coupled composite and component video routing due to its 50 Ω on-resistance, 200 MHz bandwidth, and ≤1 Ω channel matching. Its low charge injection (0.5 pC) prevents vertical interval disturbance during hot switching, and its ±15 V supply allows DC restoration circuitry to remain functional across the switch. For optimal performance in video applications, the IH5050CWE should be placed close to the connector with controlled-impedance PCB traces.
Is the IH5050CWE pin-compatible with any industry-standard analog switch footprints?
No-the IH5050CWE uses a proprietary 16-pin SOIC-W (wide-body) footprint with 0.75 mm pitch and 7.5 mm body width, distinct from standard SOIC-16 (6.0 mm width) or TSSOP-16 packages. Its pin assignments-including dual V–/V+ analog supplies, shared GND, and separate VDD-are specific to Maxim's high-voltage analog switch architecture. Board redesign is required when substituting the IH5050CWE for other analog switches.
What is the typical charge injection value for the IH5050CWE, and how does it affect precision sampling?
The IH5050CWE specifies 0.5 pC typical charge injection, measured at VANALOG = 0 V and VCONTROL = 5 V. In precision sampling applications-such as multiplexed 16-bit ADC front-ends-this low charge injection limits voltage step error on hold capacitors to less than 1 mV for 1 nF capacitance, enabling sub-LSB accuracy at 10 kSPS. This performance is validated in IH5050CWE application notes for data acquisition reference designs.
