Description

Analog Devices Inc. presents the REF194GP, a high precision, low power, and stable voltage reference. This component is part of their renowned series of voltage references that cater to a wide range of applications, including precision data converters, battery-powered devices, and industrial control systems. The REF194GP is specifically designed to offer a combination of flexibility and performance to engineers and designers, ensuring reliable operation in diverse conditions.

The REF194GP boasts an output voltage of 4.096 volts, which is a common reference voltage for 12-bit analog-to-digital converters (ADCs), ensuring compatibility with a variety of ADCs and digital-to-analog converters (DACs). Its impressive temperature coefficient, as low as 10 ppm/°C, guarantees minimal deviation over temperature changes, making it an ideal choice for applications that require high-precision measurements across a wide temperature range.

With a typical supply current of only 45 µA, this voltage reference is optimized for energy-sensitive applications. Its low power consumption does not compromise its performance, as it maintains a low dropout voltage, ensuring stable output even with minimal headroom above the output voltage. This feature is particularly beneficial for battery-operated devices where power efficiency is critical.

The REF194GP is also characterized by its low output noise, which is a crucial parameter for high-resolution signal processing. This low noise contributes to the overall performance of the system, reducing the error and increasing the accuracy of measurements. Furthermore, the long-term stability and low hysteresis of the REF194GP ensure that the voltage reference continues to perform reliably over time and through temperature cycles.

Packaged in an 8-lead PDIP, the REF194GP is designed for easy integration into a wide array of circuit designs. Its robustness and versatility make it a go-to solution for engineers who require a stable voltage reference that can deliver consistent performance without necessitating frequent recalibration or adjustments.
