ADD A COMMENT >

Analog Devices Inc. introduced a series of voltage references specifically suited for high-resolution data converters and precision applications in data acquisition systems, instrumentation, process control, and automotive battery monitoring.

With low frequency noise of 0.5 ppm, maximum temperature coefficient of 2 ppm/⁰C over the full operating temperature range of -40 ⁰C to +125 ⁰C, and a typical long-term drift of only 25 ppm/1khr, the ADR45xx series of voltage references provide high accuracy over time and temperature variations critical for many precision applications. This performance is achieved with a maximum quiescent current of 950 µA.

Key highlights:

  • Maximum TC: 2 ppm/⁰C
  • Output noise (0.1 – 10 Hz): < 1µVP-P @ 2.048 VOUT typical
  • Initial output voltage error: ±0.02 percent (max)
  • Input voltage range: 3 V to 15 V
  • Operating temperature: -40 ⁰C to +125 ⁰C
  • Output current: +10 mA source/-10 mA sink
  • Low quiescent current: 950 µA (max)
  • Low dropout voltage: 300 mV @ 2 mA (VOUT ≥ 3 V)
