Overview
The REF192FSZ-REEL is a precision band gap voltage reference from the REF19x series, manufactured by Analog Devices Inc. This device is renowned for its high accuracy and stability, achieved through a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors. The REF192FSZ-REEL is part of the micropower, low dropout voltage (LDV) devices, offering a stable output voltage from supplies as low as 100 mV above the output voltage and consuming less than 45 μA of supply current. It also features a sleep mode that reduces the supply current to less than 15 μA when enabled by a low TTL or CMOS level on the SLEEP pin.
