Detailed Description for ADR4550BRZ-R7
Product Overview
The ADR4550BRZ-R7 from Analog Devices Inc. is a fixed-output series voltage reference IC that provides a 5V output in an 8-SOIC surface-mount package. It is specified with ±0.02% tolerance, a 2ppm/°C temperature coefficient, and 2.8µVp-p noise from 0.1Hz to 10Hz. The device operates from a 5.1V to 15V input and can deliver up to 10mA of output current while drawing 950µA of supply current. The operating temperature range is -40°C to 125°C.
Key Features
- Fixed 5V series voltage reference output with ±0.02% tolerance.
- 2ppm/°C temperature coefficient and 2.8µVp-p noise from 0.1Hz to 10Hz.
- 10mA output current capability with 950µA supply current.
- 5.1V to 15V input operating range.
- 8-SOIC surface-mount package, 3.90mm width.
Applications
- Analog-to-digital or digital-to-analog conversion reference node.
- Sensor signal conditioning circuits requiring a 5V reference.
- Instrumentation and measurement front ends where reference drift affects accuracy.
- Embedded analog subsystems using a surface-mount fixed voltage reference.
Design & Procurement Notes
Design considerations center on the fixed 5V output and 5.1V to 15V input range, which sets a minimum headroom requirement for the supply rail. The 10mA output rating should be checked against the load current of downstream reference connections, while the 950µA supply current affects power budget. The 2ppm/°C coefficient, ±0.02% tolerance, and 2.8µVp-p noise from 0.1Hz to 10Hz are relevant when selecting reference placement and filtering. The 8-SOIC surface-mount package and -40°C to 125°C operating range support board layouts within that temperature envelope.
