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

2023-04-27

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.
