Product details

Dual 3.3 V reference with 20 mA drive — precision for mixed-signal chains

The LT6658BHDE-3.3#PBF is a dual-series voltage reference from Analog Devices, delivering a fixed 3.3 V output from a 5 V to 36 V input rail. 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.

Frequently asked questions

What is the tolerance and temperature drift of LT6658BHDE-3.3#PBF?

Initial tolerance is ±0.1 % and the temperature coefficient is 20 ppm/°C over the -40 °C to 125 °C junction temperature range.

Can ADR423ARMZ replace LT6658BHDE-3.3#PBF?

No — the ADR423ARMZ is a single-output reference with 0.13 % tolerance and 10 mA output current, versus the dual-output 20 mA, 0.1 % LT6658. The pinout and package differ; a board layout change is required.
