Product Introduction

Overview

The REF192GS, produced by Analog Devices Inc., is a 2.5V precision micropower, low dropout voltage (LDV) reference. This device is part of the REF19x series, which utilizes a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors to achieve high initial accuracy and a very low temperature coefficient. The REF192GS is designed to provide stable output voltage from supplies as low as 100 mV above the output voltage, making it suitable for a variety of applications requiring precise voltage referencing.

Key Features

  • Precision Voltage Reference: The REF192GS offers high initial accuracy with a maximum deviation of ±2 mV and a low temperature coefficient of 10 ppm/°C (G Grade), ensuring stable output voltage across a wide temperature range.
  • Low Dropout Voltage: The device can operate with supplies as low as 100 mV above the output voltage, making it suitable for low-voltage applications.
  • Low Supply Current: It consumes less than 45 μA of supply current and reduces to less than 15 μA in sleep mode, which is enabled by a low TTL or CMOS level on the SLEEP pin.
  • Stable Output: Provides stable output voltage over a wide range of input voltages (3 V to 15 V) and load currents (up to 30 mA).
  • Low Noise: Features low noise voltage of 25 μV p-p in the 0.1 Hz to 10 Hz frequency range.
  • Extended Temperature Range: Specified over the extended industrial temperature range of −40°C to +85°C, with typical performance specifications up to +125°C.

Applications

  • Automotive Systems: Suitable for automotive applications due to its extended temperature range and high reliability.
  • Industrial Control Systems: Used in industrial control systems where precise voltage referencing is critical.
  • Medical Devices: Applicable in medical devices requiring stable and accurate voltage references.
  • Consumer Electronics: Can be used in various consumer electronics where low power consumption and high accuracy are required.
