Quad 8-Bit DACs with
Rail-to-Rail Voltage Outputs
General Description
The MAX505 and MAX506 are CMOS, quad, 8-bitvoltages-
output digital-to-analog converters (DACs). The parts
operate with a single +5V supply or dual eN 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 tothe input latches from a common
8-bit input port. The DACs are individually selected Lh..r.pugh
address inputs A0 and Al, and updated by bringing WR low.
All MAX506 DACs share a common reference input.
All logic inputs are TTL and +5V CMOS compatible.
