ADI AD7535AQ

The AD7535 is a 14-bit monolithic CMOS D/A converter which uses laser trimmed thin-film resistors to achieve excellent linearity.

• A novel low leakage configuration (patent pending) enables the AD7535 to exhibit excellent output leakage current characteristics over the specified temperature range.
• The device is fully protected against CMOs “latch up” phenomena and does not require the use of external Schottky diodes or the use of a FET Input op-amp.
• The AD7535 is manufactured using the Linear Compatible CMOS (LC²MOS) process.
• It is speed compatible with most microprocessors and accepts TTL or CMOS logic level inputs.
• Guaranteed Monotonicity: The AD7535 is guaranteed monotonic to 14-bits over the full temperature range for all grades.
• Low Output Leakage: By tying VSS (Pin 27) to a negative voltage, it is possible to achieve a low output leakage current at high temperatures.
• Microprocessor Compatibility: High speed input control (TTL/5V CMOS compatible) allows direct interfacing to most of the popular 8-bit and 16-bit microprocessors. When interfacing to 8-bit processors CSMSB and CSLSB are separate and the 8-bit data bus is connected to both the MS Input Register and the Ls Input Register. For straight 14-bit parallel loading CSMSB and CSLSB are tied together giving one chip select to load the 14-bit word.
