RT9403A/B/C

I²C Programmable High Precision Reference Voltage Generator

General Description

Features

^z5V Supply Voltage

The RT9403A/B/C is a high precision reference voltage

generating console consisting of three I²C programmable

DACs. EachDAC 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.

^zProvide 3 Precise Voltage DACs

^zI²C Programmable 128-Steps Output Voltage

^zOutput Range and Resolution

` DAC1 & DAC2 : 0.6V to 2.1875V, 12.5mV/Step
