RS422 - Precision Programmable Reference

Download the RS422 datasheet PDF. This datasheet also covers the RS421 variant, as both devices belong to the same precision programmable reference family and are provided as variant models within a single manufacturer datasheet.

General Description

The RS421 and RS422 device are three-terminal adjustable shunt regulators, with a guaranteed thermal stability over applicable temperature ranges.

The output voltage can be set to any value between VREF (approximately 1.18V) and 36V with two external resistors.

Key Features

  • Reference Voltage Tolerance at 25°C 0.5%.
  • Programmable output voltage to 36V.
  • Low dynamic output impedance 0.1Ω.
  • Sink current capability of 0.5mA to 100mA.
  • Equivalent full-range temperature coefficient of 50ppm/°C typical.
  • Temperature compensated for operation over full rated operating temperature range.
  • Low output noise voltage.
  • Fast turn on response.
  • Operation junction temperature from -40°C to 150°C.
  • Le.
