Voltage Reference products provide a stable reference voltage to a microcontroller or other voltage-sensitive device. The LM4132AMF-1.8/NOPB voltage reference is an integrated double-precision voltage reference that can be used to generate an exact reference voltage from a single power supply. It is specifically designed for use in high-precision applications.

The LM4132AMF-1.8/NOPB is a temperature compensated, low-power voltage reference. It operates on a wide voltage range of 1.8V to 5.5V and is optimized for precision voltage references at 3.3V and 5V. Its low-noise, low-drift feature makes it ideal for applications that require ultra-low power consumption, high accuracy, and fast response time.

The application field the LM4132AMF-1.8/NOPB is wide and includes precision data converters, embedded systems, low-power system-on-chips, and communication interface circuits. In particular, it is used in precision voltage regulators and as a reference for high-precision analog-to-digital (ADC) and digital-to-analog (DAC) converters. It is also used for low-power devices, such as touchscreens, battery-powered devices, and medical instruments.

The LM4132AMF-1.8/NOPB can generate a high-accuracy reference voltage of up to 600 mV. The reference voltage is internally trimmed to ±10 mV accuracy and has a temperature coefficient of only 0.25 ppm/°C. It also features low noise, fast response time, and low-power operation. Additionally, the voltage reference supports fast load transients and is RoHS-compliant.

The working principle of the LM4132AMF-1.8/NOPB is based on a simple controller-driven voltage reference with a hysteretic topology. The hysteretic topology works by actively comparing the incoming voltage to a predetermined reference voltage. When the incoming voltage exceeds the reference voltage, the circuit will switch to a higher voltage level, thereby increasing the voltage output. Inversely, when the input voltage is below the reference voltage, the circuit will switch to a lower voltage level, thus decreasing the voltage output. This hysteretic topology also ensures a fast response time and very low quiescent current consumption (< 300 nA).

The LM4132AMF-1.8/NOPB is a highly efficient and reliable voltage reference that provides an accurate and low-noise reference voltage for precision applications. Its widest voltage range, low-noise and low-drift features make the LM4132AMF-1.8/NOPB an attractive choice for precision voltage reference applications.
