REF191FS datasheet

Description :

The REF191FS, REF19x series precision band gap voltage references use a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors to achieve a very low temperature coefficient and high initial accuracy.

The REF19x series is made up of micropower, low dropout voltage (LDV) devices, providing stable output voltage from supplies as low as 100 mV above the output voltage and consuming less than 45 μA of supply current. In sleep mode, which is enabled by applying a low TTL or CMOS level to the SLEEPpin, the output is turned off and supply current is further reduced to less than 15 μA.

Features :

1. Initial Accuracy: 62 mV max
2. Temperature Coefficient: 5 ppm/°C max
3. Low Supply Current: 45 mA max
4. Sleep Mode: 15 mA max
5. Low Dropout Voltage
6. Load Regulation: 4 ppm/mA
7. Line Regulation: 4 ppm/V
8. High Output Current: 30 mA
9. Short Circuit Protection

Applications :

1. Portable Instrumentation
2. A-to-D and D-to-A Converters
3. Smart Sensors
4. Solar Powered Applications
