The MX7845JP is a 12-bit, voltage-output, 4-quadrant, multiplying digital-to-analog converter (DAC). A precision internal output amplifier and thin-film resistors, laser-trimmed at the wafer level, maintain accuracy over the full operating temperature range. The output amplifier is internally compensated and drives ±10V into a 2kΩ load. The MX7845JP has buffered latches that are easily interfaced with microprocessors. Data is transferred into the input register from a 12-bit-wide data path. The input registers are controlled by standard active-low CHIP SELECT (active-low CS) and active-low WRITE (active-low WR) signals. For stand-alone operation, the active-low CS and active-low WR inputs are grounded, making all latches transparent. All logic inputs are level-triggered and compatible with TTL and +5V CMOS logic levels. For a detailed description of MX7845JP operation, refer to the MAX501/MAX502 data sheet.
