Overview
DA8444A.
005 May 31, 1996 MAS8444A OCTAL 6-BIT TRIMMER IC • Eight discrete DACs 2 • I C-bus slave receiver • Voltage output DESCRIPTION The MAS8444a comprises eight digital to analog converters (DACs) each controlled by a two-wire I2C bus.
The DACs are individually programmed using an 6-bit word to select an output from one of 64 voltage steps.
The maximum output voltage of all DACs is set by Vmax.
At power-on all outputs are set to their lowest value.
The I2C-bus slave receiver has 3 programmable address pins (2 in the SO16 package).
FEATURES • Rail to rail output stages • Octal 6-bit DACs on a single monolithic chip • Power   supply¡ range from +5V to +12V • -25 C to +85 C temperature range • 16-pin PDIL and SO package • pin to pin compatibility with TDA8444 APPLICATION • Trimmer replacement • Automatic gain control • High resolution monitors BLOCK DIAGRAM SDA 3 SCL 4 A0 5 A1 6 A2 7 I C Bus Slave Receiver 2 6-BIT DAC DAC7 6-BIT DAC DAC6 DAC5 6-BIT DAC 6-BIT DAC 6-BIT DAC ...
