3PEAK Launches the TPR50, a High-performance Voltage Reference with an Initial Accuracy of 0.05% and Temperature Drift of 2.5 ppm °C !


3PEAK (stock code: 688536), a semiconductor company focusing on the development of high-performance analog chips and embedded processors, launched a high-precision, low-temperature drift voltage reference —TPR50. Featuring an initial accuracy of 0.05% and a temperature drift of 2.5 ppm/°C over the full temperature range of –40°C to +125°C, the product is widely used in testing and measuring, industrial instruments, data acquisition, and medical devices.

• Wide Input Range: 3 V-15 V
• Multiple Fixed Output Versions:
  1.25 V, 2.048 V, 2.5 V, 3 V, 3.3 V, 4.096 V, 4.5 V, 5 V
• Low Temperature Drift:
  Typical value 1 ppm/°C from 0°C to +70°C
  Typical value 2 ppm/°C from –40°C to +105°C
  Typical value 2.5 ppm/°C from –40°C to +125°C
• High Initial Accuracy:
  Initial Accuracy up to 0.05%
• Low Noise: 3 μVpp/V
• Wide Operating Temperature Range: –40°C to +125°C
• Package: SOP8

The TPR50 series has an output current capability of ±10 mA, and its output can bypass the operational amplifier and directly connect to the ADC as a reference voltage. It has a wide input range of 3 V–15 V. The following diagram shows the typical application circuit of TPR50. The output capacitor ranges from 0.1 µF to 100 µF. The NR connects to a capacitor of 10 nF or above to ground, thus reducing the output voltage noise of TPR50.




Featuring high initial accuracy, low temperature drift, and low time drift, the TPR50 series provides excellent voltage reference support for applications such as testing and measuring, industrial instruments, data acquisition, and medical devices.
