REF191GSZ Description

Short technical summary and product information.

The REF191GSZ from Analog Devices is a precision band gap voltage reference designed for applications requiring stable voltage output. It utilizes a patented temperature drift curvature correction circuit and laser-trimmed resistors to achieve a low temperature coefficient of 5 ppm/°C and an initial accuracy of ±2 mV.

 

This micropower device consumes less than 45 μA of supply current and features a low dropout voltage. A sleep mode is available, reducing supply current to under 15 μA when enabled via the SLEEP pin. The REF191GSZ is specified for the extended industrial temperature range of -40°C to +85°C.

 

It is available in an 8-lead SOIC package, suitable for surface mounting. The REF191GSZ is ideal for portable instruments, ADCs and DACs, smart sensors, and solar-powered applications where low power and high accuracy are critical.

 

Key electrical characteristics include a maximum output current of 30 mA, load regulation of 4 ppm/mA, and line regulation of 4 ppm/V. The device also includes short-circuit protection.
