Exar Corporation MP7636A
The MP7636A is manufactured using advanced thin film resistors on a double metal CMOS process. The MP7636A incorporates a unique bit decoding technique yielding lower glitch, higher speed and excellent accuracy over temperature and time. The MP7636A is packaged in a 20-pin 300 mil wide DIP and is a direct 16-bit replacement for the 12-bit DAC1230 series.FEATURES

GENERAL DESCRIPTION
16-bit differential non-linearity is achieved with minimal laser trim. Full pin-for-pin compatibility allows existing systems to be upgraded to 16 bits without hardware modification. The MP7636A provides 16-bit data loading through 8 input data lines for direct interface to 8-bit data buses. All data loading and data transfer operations are identical to the WRITE cycle of a static RAM. The MP7636A uses a unique circuit which significantly reduces transients in the supplies during DATA bus transitions at CS = 1.
