The Analog Devices 1B21AN is a high-performance, isolated voltage-to-current converter designed for industrial applications requiring accurate current loop signal transmission. It integrates analog input conditioning, modulator, demodulator, and output stages in a single 38-DIP package.
The device accepts programmable input voltage ranges from 0V to 1V up to 0V to 10V and provides two selectable output current ranges: 4 mA to 20 mA and 0 mA to 20 mA. It features 1500 V rms common-mode isolation, 90 dB minimum common-mode rejection, and typical nonlinearity of ±0.02%. Key thermal characteristics include a gain temperature coefficient of ±50 ppm/°C and an offset temperature coefficient of ±300 nA/°C.
With a maximum load resistance of 1.35 kΩ and a loop supply voltage up to 30 V, the 1B21AN is suitable for harsh environments with high common-mode interference. The through-hole 38-DIP package measures 0.7" × 2.1" × 0.35" (17.78 mm × 53.34 mm × 8.89 mm), facilitating easy integration into existing designs.
The input voltage range is programmable from 0V to 1V up to 0V to 10V.
The 1B21AN can be programmed for 4 mA to 20 mA or 0 mA to 20 mA output.
The isolation voltage is 1500 V rms.
The operating temperature range is -40°C to +85°C.
The package is a 38-DIP (0.500", 12.70mm), 8 Leads through-hole package.
It is marked as RoHS3 compliant, but this is unverified.
The load resistance range is 0 to 1.35 kΩ maximum.
