TLC7225 说明

The TLC7225 consists of four 8-bit voltage-output digital-to-analog converters (DACs), with output buffer amplifiers and interface logic with double register-buffering.

Separate on-chip latches are provided for each of the DACs. Data is transferred into one of these data latches through a common 8-bit TTL/CMOS-compatible (5 V) input port. Control inputs A0 and A1 determine which DAC is loaded when WR\ goes low. Only the data held in the DAC registers determines the analog outputs of the converters. The double register buffering allows simultaneous update of all four outputs under control of LDAC\. All logic inputs are TTL- and CMOS-level compatible and the control logic is speed compatible with most 8-bit microprocessors.
