RT9403A
Description
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.
