Overview

The MAX14866UTM device is a 16-channel, high-voltage (HV) analog SPST switch designed primarily for high-voltage multiplexing in ultrasonic applications. The MAX14866UTM is powered by a single low voltage supply (+5V), eliminating the need for a dedicated high voltage supply, saving costs and simplifying the system. In addition, for in-probe applications, the high voltage power supply does not need to be associated with the MAX14866UTM in the probe/transducer probe, thereby improving safety and simplifying safety regulatory compliance.

The MAX14866UTM performs well in several areas, including bandwidth (up to 50MHz), charge injection (<100pC) and linear transmit input range (up to 210VPKPK). The low-signal switch RDSON is typically about 7Ω above and below 0V and remains flat over the entire input range, ensuring excellent linearity.

The MAX14866UTM comes in a TQFN package, which is the industry standard 48-pin, 7mm x 7mm package.

Key characteristics

1, high voltage and wide voltage support ‌

The MAX14866UTM supports single power supply (1.7V~5.5V), and can process 210V peak-peak linear signals without additional high voltage power supply, simplifying system power design ‌.

The MAX14866UTM integrates a 16-channel SPST switch with a typical on-resistance of 7Ω (maximum 13Ω) and a matching error of 0.21Ω to ensure consistent signal transmission ‌.

‌2. High frequency performance and low interference ‌

MAX14866UTM bandwidth up to 500MHz (best in its class), -3dB bandwidth 50MHz, suitable for ultrasonic probe and other high frequency signal routing ‌.

Charge injection <100pC, crosstalk suppression up to -65dB@5MHz, reduce the signal distortion during switching ‌.

‌3. Reliability design ‌

Operating temperature range 0°C to 85°C, MAX14866UTM in 48-pin TQFP package (5.6x5.6mm), surface mount compatible with high density PCB layout ‌.

The switching time is 4µs (on/off), the static leakage current is less than or equal to 1µA, and the MAX14866UTM can be optimized for low-power scenarios ‌.

Typical application scenario ‌

‌1. Medical ultrasound imaging system ‌

The MAX14866UTM is used for signal multiplexing of ultrasonic probes to achieve high resolution imaging through high voltage channel switching, compatible with probe integrated design ‌.

‌2. Industrial Test and Automation ‌

In PLC and ATE devices, MAX14866UTM realizes sensor array signal routing and supports multi-channel synchronous acquisition ‌.

The MAX14866UTM ADAPTS to the high voltage power module to ensure signal switching stability ‌.

‌3. Communication infrastructure ‌

The MAX14866UTM is integrated in the base station antenna switching system to process high-frequency signal routing and reduce system complexity ‌.
