DAC 4-CH R-2R 8-bit 24-Pin SSOP Tube

The AD7225 contains four 8-bit voltage output digital-to-analog converters, with output buffer amplifiers and interface logic on a single monolithic chip. Each D/A converter has a separate reference input terminal. No external trims are required to achieve full specified performance for the part. The double-buffered interface logic consists of two 8-bit registers per channel -an input register and a DAC register. Control inputs A0 and A1 determine which input register is loaded when WR goes low. Only the data held in the DAC registers determines the analog outputs of the converters. The double-buffering allows simultaneous update of all four outputs under control of LDAC. All logic inputs are TTL and CMOS (5V) level compatible and the control logic is speed compatible with most 8-bit microprocessors. Specified performance is guaranteed for input reference voltages from +2V to +12.5V when using dual supplies. The part is also specified for single supply operation using a reference of +10V. Each output buffer amplifier is capable of developing +10V across a 2 K(Ohm) load. The AD7225 is fabricated on an all ion-implanted high speed Linear Compatible CMOS (LC2MOS) process which has been specifically developed to integrate high-speed digital logic circuits and precision analog circuitry on the same chip.
