ZJR1002-9BUTBR

The ZJR1001 and ZJR1002 offer a low noise, low power and low-drift voltage reference in a small 6-pin SOT23 package. They are suitable for data acquisition applications with high resolution (14-bit or more), such as precision instruments and test equipment. Because of the low dropout feature, ZJR1001 and ZJR1002’s input voltage can start from 300 mV higher than the output voltage, which can simplify the system power supply design. The supply current is just 130 μA, making them suitable for portable devices while maintaining high performances. By optimized design and proprietary trimming, ZJR1001 and ZJR1002 achieve the temperature coefficient within 5 ppm/°C and initial accuracy within ±0.05%. This simplifies or even allows the user to skip system calibration for most applications. ZJR1001 offers noise filter option for wideband applications, and ZJR1002 can enable the output in Kelvin connection. The ZJR1001 and ZJR1002 are available in a 6-lead SOT23 package and are specified over the extended industrial temperature range of -40 °C to +125 °C.
