AD421BN

The AD421BN is an integrated circuit (IC) component developed by Analog Devices. It is a complete voltage-to-current converter chip that offers precise and accurate DC current output. This IC is widely used in applications where a voltage signal needs to be converted into a proportional current output, such as industrial process control, automation, and instrumentation systems. One of the key features of the AD421BN is its high accuracy and stability. It provides an output current that is directly proportional to the input voltage signal, with a conversion accuracy of ±0.05% over the specified temperature range. This makes it ideal for applications that require precise and reliable current outputs. The IC also offers a wide range of output current options. It can generate programmable output currents ranging from 0 mA to 20 mA, making it versatile for various applications. The user can easily set the desired current level by configuring a precision external resistor connected to the IC's output pin. To maintain stability and accuracy, the AD421BN incorporates a highly stable on-chip voltage reference. This reference eliminates the need for an external voltage reference, reducing system complexity and cost. Additionally, the IC includes a low-drift output amplifier that ensures minimal output impedance and excellent linearity. Another notable feature of the AD421BN is its low power consumption. It operates from a single power supply voltage ranging from 12V to 36V, consuming only 1.4mW of power
