The ISL21009 FGA™ voltage references are extremely low power, high precision, and low noise voltage references fabricated on Intersil’s proprietary Floating Gate Analog technology. The ISL21009 features very low noise (4µVP-P for 0.1Hz to 10Hz), low operating current (180µA, Max), and 3ppm/°C of temperature drift. In addition, the ISL21009 family features guaranteed initial accuracy as low as ±0.5mV
