NOTES:
1 Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.
2 Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky diode clamps (HP5082-2835) from input pin to the supplies. All inputs have protection diodes which will protect the device from short transients outside the supplies of less than 100mA for less than 100ms. 3 GND refers to AGND and DGND.

Description

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. 16-bit differential non-linearity is achieved with minimal laser trim.

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. 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.
