BLUESCHIP Co., Ltd. is the world's largest distributor of electronic components, a leading global distributor specializing in integrated circuits (IC), PMIC, memory, logic, linear, interface, embedded FPGA, CPLD, microprocessor, microcontroller , Resistors, capacitors, switches, sensors, sensors, RF/IF and RFID, semiconductor modules, relays,

Optoelectronics and discrete semiconductors. We cooperate with more than 1 million world-renowned manufacturers, have more than 15 million stocks, are RoHS compliant/lead-free and environmentally friendly, and provide high-quality electronic components to solve your supply chain problems such as component procurement.

AD8628ARZ and AD8629ARZ are zero-drift amplifier series manufactured by ADI (Analog Devices, Inc.), AD8628ARZ is Zero-Drift Amplifier 1 Circuit Rail-to-Rail 8-SOIC, AD8629ARZ is Zero-Drift Amplifier 2 Circuit Rail-to-Rail 8 -SOIC. These two amplifiers have ultra-low offset, drift and bias current characteristics. The offset voltage of the AD8628ARZ and AD8629ARZ is only 1 µV, the offset voltage drift is less than 0.005 ìV/°C, and the noise is only 0.5 µV peak-to-peak (0 Hz to 10 Hz), making it suitable for applications where error sources are not tolerated. The drift of these devices in the operating temperature range is close to zero, which is extremely beneficial for position and pressure sensors, medical equipment and strain gauge amplifier applications.
