MAX506BCWP+

The MAX505 and MAX506 are CMOS, quad, 8-bit voltage-output digital-to-analog converters (DACs). The parts operate with a single +5V supply or dual ±5V supplies. Internal, precision output buffers swing rail-to-rail. The reference input range includes both supply rails. Offset, gain, and linearity are factory calibrated to provide 1LSB total unadjusted error (TUE) over the full operating temperature range. The MAX505 contains double-buffered logic inputs, which allow all analog outputs to be simultaneously updated using the asynchronous load DAC (LDAC) control signal. The MAX505 also has four separate reference inputs, allowing each DAC's full-scale range to be independently set. The MAX506 has separate input latches for each of its four DACs. Data is transferred to the input latches from a common 8-bit input port. The DACs are individually selected through address inputs A0 and A1, and updated by bringing WR low. All MAX506 DACs share a common reference input. All logic inputs are TTL and +5V CMOS compatible.
