MC6890

® MOTOROLA Advance InforIDation MPU-BUS-COMPATIBlE 8-BIT 0-TO-A CONVERTER The MC6890 is a self-contained, bus-compatible, 8 bit (±0.19% accuracy) D-to-A converter system capable of interfacing directly with 8-bit microprocessors. Available in both commercial and military temperature ranges, this monolithic converter contains master/slave registers to prevent transparency to data transitions during active enable; a lasertrimmed, low-TC, 2.5 V precision bandgap reference; and high stability, laser-trimmed, thin-film resistors for both reference input and output span and bipolar offset control. A reset pin provides for overriding stored data and forcing lout to zero.
