Frequently Asked Questions
What is the output voltage and accuracy of the LM4132EMF-1.8/NOPB?
The LM4132EMF-1.8/NOPB provides a fixed 1.8V output voltage with an initial accuracy of 0.05% (±0.9mV). This tight tolerance, combined with a 20ppm/°C temperature coefficient, ensures a highly stable reference across the operating temperature range, making it suitable for precision ADC/DAC applications.
What is the input voltage range and dropout voltage for the LM4132EMF-1.8/NOPB?
The device operates with an input voltage range of 2.191V minimum to 5.5V maximum, with an absolute maximum rating of 6V. The typical dropout voltage is 0.23V (nominal) with a maximum of 0.4V, allowing the device to function effectively in low-supply-voltage environments common in battery-powered and portable designs.
How does the shutdown enable feature work on the LM4132EMF-1.8/NOPB?
The LM4132EMF-1.8/NOPB includes a dedicated shutdown enable pin that allows the reference to be disabled under microcontroller or system control, significantly reducing quiescent current during idle periods. This feature is particularly valuable in power-sensitive applications such as IoT devices, wearables, and handheld instruments that require active power management.
What package does the LM4132EMF-1.8/NOPB come in and what are alternative packages?
The LM4132EMF-1.8/NOPB is housed in a SOT-23 5-pin (SC-74) surface-mount package, which provides a very small PCB footprint ideal for space-constrained designs. Texas Instruments also offers the LM4132 series in other package options. The device is RoHS-compliant and lead-free (NOPB suffix indicates no lead finish).
What are typical applications for the LM4132EMF-1.8/NOPB voltage reference?
The LM4132EMF-1.8/NOPB is commonly used as a precision voltage reference for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and data acquisition systems. It is also well-suited for portable medical devices, industrial sensor interfaces, calibration equipment, and battery-powered IoT systems where a stable 1.8V reference with low power consumption is required.
