ADR3625 Output Voltage Reference

Analog Devices' ADR3625 is a precision, micropower, high current output voltage reference

Image of Analog Devices' ADR3625 Output Voltage ReferenceADI's ADR3625 is a low-power, high-precision voltage reference featuring a maximum temperature coefficient of 3 ppm/°C for the B grade in an 8-lead MSOP. Capable of sourcing up to 70 mA, the ADR3625 is an exceptional replacement to standard low dropout (LDO) regulators. For high accuracy, the output voltage and temperature coefficient are trimmed during production using ADI's proprietary DigiTrim® technology.

The low thermal hysteresis (-7 ppm) and low long-term drift (160 ppm at 4500 Hr) improve system lifetime accuracy. A minimum load capacitance of 0.1 µF is required for operation. The ADR3625 is specified over the -40°C to +125°C operating temperature range.

The EVAL-ADR3625EBZ evaluation board evaluates the ADR3625, which is included on the board.
