Analog Devices Inc. ADR291FRZ
- Part Number:
- ADR291FRZ
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3750800-ADR291FRZ
- Description:
- IC VREF SERIES 2.5V 8SOIC
- Datasheet:
- ADR291FRZ
Description
The ADR291 is a low noise, micropower precision voltage reference that uses an XFET reference circuit. The XFET architecture offers significant performance improvements over traditional band gap and buried Zener-based references. Improvements include one quarter of the voltage noise output of band gap references operating at the same current, very low and ultralinear temperature drift, low thermal hysteresis, and excellent long-term stability.
The ADR291 is a series voltage reference providing a stable and accurate output voltage from supplies as low as 2.8 V. The output voltage is 2.5 V. Quiescent current is only 12 μA, making these devices ideal for battery-powered instrumentation. Output accuracy is ±8.3 mV maximum. Temperature coefficient is 15 ppm/°C maximum. Line regulation and load regulation are typically 30 ppm/V and 30 ppm/mA, maintaining the overall high performance of the reference.
Features
Qualified for automotive applications
Supply range: 2.8 V to 15 V
Supply current: 15 μA maximum
Low noise: 8 μV (0.1 Hz to 10 Hz)
High output current: 5 mA
Temperature range: -40°C to 125°C
Pin compatible with REF02/REF19x
Applications
Automotive Li-Ion Battery Measurement
Analog-to-digital and digital-to-analog converter reference
