OCTAL 6-BIT TRIMMER IC

• Eight discrete DACs

• I

C-bus slave receiver

• Voltage output

DESCRIPTION

The MAS8444a comprises eight digital to analog

converters (DACs) each controlled by a two-wire I

2C

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 I

2C-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
