RT9403B - High Precision Reference Voltage Generator

Download the RT9403B datasheet PDF. This datasheet also covers the RT9403A variant, as both devices belong to the same high precision reference voltage generator family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • The RT9403A/B/C is a high precision reference voltage generating console consisting of three I2C programmable DACs. Each DAC output voltage is controlled by 7 digital bits that are programmed by the I2C interface. The RT9403A/B/C features adjustable output slew rate, low switching glitch and adequate driving capability. The RT9403A/B/C is available in SOT-23-8 package. Ordering Information RT9403A/B/C Package Type V8 : SOT-23-8 z 5V Supply Voltage z Provide 3 Precise Voltage DACs z I2C Program.
