The dual-output architecture lets it serve two independent ADC reference inputs or a reference and a bias rail from one package. ## 0.1 % tolerance, 20 ppm/°C drift — the noise floor matters Output current is 20 mA, enough to drive the reference input of multiple ADCs or a precision DAC plus a small buffer without an external op-amp. ## 16-DFN exposed pad — thermal and layout considerations The 16-WFDFN package (4 mm x 3 mm) with an exposed pad requires a thermal land on the PCB to pull heat from the die.","metaTitle":"Analog Devices LT6658BHDE-3.3#PBF Voltage Reference, 0.1%","metaDescription":"Active production.
