MAXIM MAX502AENG+

The MAx501/MAx502 are 12-bit, 4-quadrant, voltageoutput, multiplying digital-to-analog converters (DACs) with an output amplifier. Thin-film resistors, laser trimmed at the wafer level, maintain accuracy over the full operatina temperature range. The MAx501/MAx502 have buffered latches that are easily interfaced with microprocessors. Data is transferred into the input register in either a right-justified 8+4-bit format (MAx501) or with a 12-bit-wide data path (MAx502). In the MAX501, an LDAC signal transfers data from the input register to the DAC register. In the MAX502, the input registers are controlled by standard CHIP SELECT (CS) and WRITE (WR) signals. For standalone operation, the CS and WR inputs are grounded, making all latches transparent. All logic inputs are level triggered and compatible with TTL and +5V CMOS logic levels. The internally compensated, low-input offset-voltage output amplifier provides an output voltage from +10V to -10V while sourcing and sinking up to 5mA.
