Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as “Mingjiada”) is now supplying genuine ADI (Analog Devices) REF192 precision reference voltage sources to its customers.
Product Model: REF192
Manufacturer: Analog Devices Inc. (ADI)
Product Series: REF19x Series
Output Voltage: 2.5V
Product Description: High-precision, ultra-low-power, low-dropout voltage reference
REF192 Product Overview
The REF192 is a 2.5V output model in ADI’s REF19x series of precision bandgap reference voltage sources. This series employs a patented temperature drift curvature correction circuit and laser-trimmed, high-stability thin-film resistors to achieve an extremely low temperature coefficient and high initial accuracy.
The REF192 is a low-power, low-dropout (LDV) device characterized by its ability to operate stably at a supply voltage just 100 mV higher than the output voltage, while consuming extremely low supply current. This makes it ideal for portable, battery-powered, and high-precision analog systems with stringent power consumption and space constraints.

REF192 Key Features and Benefits
High Precision and Stability: Utilizes a patented curvature correction circuit and laser-trimmed thin-film resistors to provide a stable 2.5 V output across the full temperature range, with initial accuracy as high as ±2 mV and temperature drift as low as 5 ppm/°C.
Ultra-Low Power Consumption: Operating current is less than 45 µA and drops further to below 15 µA in sleep mode, significantly extending the battery life of battery-powered devices.
Low Dropout (LDV) Design: Operates normally with an input-to-output voltage difference as low as 100 mV, supporting low-voltage power supply systems and improving power supply efficiency.
Robust Drive Capability: Delivers an output current of up to 30 mA, capable of directly driving the reference inputs of most ADCs/DACs without the need for additional buffering.
Sleep Mode: The output can be disabled via the SLEEP pin to further reduce power consumption, making it suitable for low-power systems that operate intermittently.
Typical Applications
The REF192’s high precision and low power consumption make it widely used in the following applications:
Portable instruments: multimeters, handheld test equipment
Reference voltage sources for high-precision ADCs and DACs
Smart sensors and transmitters
Solar-powered devices
Loop-powered (4–20 mA) instruments
