MAX502AEWG+

The MAX502AEWG+ is a voltage output, 12bit multiplying DAC in 24 pin WSOIC package. It is a 4 quadrant, voltage output, multiplying digital to analogue converter (DAC) with an output amplifier. Thin film resistors, laser trimmed at the wafer level, maintain accuracy over the full operating temperature range. Data is transferred into input register in either a right justified with a 12bit wide data path. 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. The internally compensated, low input offset voltage output amplifier provides an output voltage from +10V to -10V while sourcing and sinking up to 5mA. It is used in automatic test equipment, digital attenuators, digital to 4mA to 20mA converters, programmable power supplies, programmable gain amplifiers and servo controls.
