RT9403D/E/F/G
I2C Programmable High Precision Reference Voltage Generator
General Description
The RT9403D/E/F/G 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
RT9403D/E/F/G features adjustable output slew rate, low
switching glitch and adequate driving capability. The
RT9403D/E/F/G is available in SOT-23-8 package.
