MAS8444A Datasheet | Unknown Manufacturer

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 prises 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 patibility 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 6-BIT DAC DAC4 DAC3 DAC2 DAC1 Vmax 2...
