- Low-voltage operation supporting supply rails as low as 1.8 V, making it well-suited for battery-powered handheld and IoT devices requiring extended runtime
- 5-pin SOT-23 package occupying minimal PCB area for integration into space-constrained portable designs alongside other signal-chain components
Applications
The MAX4514CUK+T is used in portable and battery-powered equipment to switch audio signals, sensor outputs, and reference voltages between circuit blocks without signal degradation. In data acquisition systems, it enables multiplexing of analog sensor inputs to a single ADC input with low charge injection and minimal off-isolation leakage. Medical wearables, handheld test instruments, and IoT sensor nodes benefit from its low-voltage operation and compact SOT-23 footprint.

Frequently Asked Questions
What supply voltage range does the MAX4514CUK+T support, and how does this benefit battery-powered designs?
The MAX4514CUK+T operates from supply voltages as low as 1.8 V up to 5.5 V, covering single-cell Li-ion (2.7 V to 4.2 V), two-cell AAA (2.0 V to 3.0 V), and standard 3.3 V and 5 V logic rails. This wide range means the switch can remain in service as a battery discharges from 4.2 V to below 3 V without requiring a regulator, extending system runtime in portable instruments and wearables.
In what scenarios is the MAX4514CUK+T preferred over a general-purpose MOSFET for analog signal switching?
The MAX4514CUK+T is preferred when the analog signal path must be switched with low charge injection and predictable on-resistance, which discrete MOSFETs do not guarantee without careful biasing. In audio muting circuits, sensor input multiplexers, and reference voltage selection networks, the MAX4514's controlled charge injection of typically a few picocoulombs prevents the voltage glitches that a discrete MOSFET gate transition would introduce onto signals in the millivolt range.
How does the SPST normally-open configuration of the MAX4514CUK+T affect circuit failsafe behavior?
The normal position of the MAX4514CUK+T is open (NO), meaning the switch is disconnected when the control input is at logic low. In failsafe circuit design, this means a loss of control signal (stuck low or floating low) disconnects the signal path rather than leaving it connected. This is the preferred configuration for protecting sensitive ADC inputs from overdriven sources in powered-down subsystems, which operate at 3.3 V or 5 V signal levels.
