Product Details

The ADR3625 is a low power, high precision voltage reference that features 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 the Analog Devices, Inc., 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.
