•

Fixed Output Voltages of 2.048 V, 2.5 V, 3 V,

versatile, easy-to-use references that cater to a vast

4.096 V, 5 V, 8.192 V, and 10 V

array of applications. The 2-pin fixed-output device

stable with all capacitive loads. Additionally, the

reference offers low dynamic impedance, low noise,

Max 1.0%, 150 ppm/°C – D Grade

and Zener-zap reverse breakdown voltage trim during

wafer sort to offer four output voltage tolerances,
