RHF100 Evaluation Board

EVAL-RHF100

Overview

The EVAL-RHF100 product evaluation board of STMicroelectronics is designed to help characterize the RHF100 device. This rad-hard device is a 1.2 V, precision, low-power, ± 0.15 % fixed shunt, voltage reference with a typical average temperature co-efficient of 5 ppm/ºC and is housed in a Flat-10 ceramic package. This data brief provides a brief description of the EVAL-RHF100 product evaluation board and presents the EVAL-RHF100 schematic together with the top and bottom layers of the board.

For further details on STMicroelectronics' RHF100 device, please refer to the product datasheet.

Main features

Designed for Flat-10 package
Used to perform on-board characterization of the RHF100 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 18 kΩ, with a power supply voltage of 3.3 V this gives a cathode current of about 110 μA
If RHF100 device is soldered onto the EVAL-RHF100, R1, R2, and Cn1 are not fitted onto the PCB
