概要 ADR421ARZ

The ADR421ARZ is a precision voltage reference integrated circuit manufactured by Analog Devices. It is a low-power, high-precision voltage reference with an initial accuracy of ±0.1% and a temperature coefficient of 15 ppm/°C. This device operates with a supply voltage range of 4.5V to 18V and provides a stable output voltage of 2.048V.The ADR421ARZ is housed in a small surface-mount package, making it suitable for space-constrained applications. It also has low output noise, high output current drive capability, and excellent long-term stability. This voltage reference is ideal for precision analog-to-digital converters, data acquisition systems, industrial instrumentation, and automotive applications.Key features of the ADR421ARZ include low operating current of 140 μA, low output impedance of 3 Ω, and a temperature operating range of -40°C to +125°C. It also has built-in short-circuit and thermal overload protection for enhanced reliability.
