Cissoid CHT-BG3M Series

Cissoid CHT-BG3M Series
The Polaris CHT-BG3M high temperature voltage reference series from Cissoid offers a voltage reference range between 2.5V and 12V. These voltage references are compatible with high temperature environments with a typical operation temperature range from -55°C to +225°C. The CHT-BG3M series from Cissoid has a minimum dropout voltage of 1.5V with a load current lower than 1mA and 2.5V at 3mA load current (for CHT-BG3M-025, min dropout is 2V @ 1mA and 3V @ 3mA), with a total accuracy of ±2% and a maximum drift with temperature of 70ppm.
  • High temperature voltage reference
  • Voltage reference values of 2.5V, 3.3V, 5V, 9V, 10V and 12V
  • Dropout voltage at 1mA is 1.5V to 15V (CHT-BG3M-025 min dropout is 2V)
  • Dropout voltage at 3mA is 2.5V to 15V (CHT-BG3M-025 min dropout is 3V)
  • Quiescent current consumption of 700µA
  • Maximum output current of 3mA at 225°C
  • Total accuracy of ±2%
  • Typical operating temperature range −55°C to +225°C
  • Maximum drift with temperature 70ppm
  • Validated at +225°C for 30000 hours (and still on-going)
  • Available in TO-39 package (other packages available on request)

Typical Applications for the CHT-BG3M series from Cissoid include:

  • Well logging
  • Automotive
  • Aeronautics
  • Aerospace

Cissoid CHT-BG3M Specifications

1. For CHT-BG3M-025, min dropout is 2V at 1mA and 3V at 3mA
2. Input voltage cannot exceed 25V
3. ppm are defined as [d(Vout)/d(T)]/Vout. For 5V mode, 70ppm corresponds to 350µV/°C
4. Defining "x" as the nominal voltage, the line regulation is better than x/5 mV/V
5. Defining "x" as the nominal voltage, the minimum power supply rejection ratio is 66-1.2x.db
6. Defining "x" as the nominal voltage, typical noise level is (x/5)*240µVRMS
