EVAL-RHF1009A：RHF1009A Evaluation board
The EVAL-RHF1009A product evaluation board of STMicroelectronics is designed to help
characterize the RHF1009A device. This rad-hard device is a low-power adjustable 2.5 V to 5.5
V, ± 0.15 % fixed shunt, voltage reference with a typical average temperature co-efficient of
10 ppm/ºC and is housed in a Flat-10 ceramic package. This data brief provides a brief
description of the EVAL-RHF1009A product evaluation board and presents the EVAL-RHF1009A
schematic together with the top and bottom layers of the board.
Key Features
- Designed for Flat-10 package
- Used to perform on-board characterization of the RHF1009A prior to integration of STMicroelectronics' products
- Resistor and capacitor footprints implemented for 0805 series
- Two decoupling capacitors implemented on power supply pin and output pin to benefit from maximum performance of ST products
- R3 (cathode) resistor set to 6.8 kΩ, with a power supply voltage of 3.3 V this gives a cathode current of about 110 μA
- If RHF1009A device is soldered onto the EVAL-RHF1009A, Cn1 is fitted onto the PCB and shorted to get an output voltage of 2.5 V. If a different output voltage than 2.5 V to 5.5 V is needed, remove the jumper located on Cn1 and place the adequate value of R1, R2, and R3
