Overview

Product Details

The PM-7543isa 12-bitresolution.multiplying, CMOS D/A converter. which features serial data input and current output. Serial data input reduces pin count and allows the PM-7543 to be placed in a smaller package. saving PC board space. Improved analog parameters such as digital charge injection, powersupply rejection. output capacitance, feedthrough error, fast microprocessor interface, and improved ESD protective circuitry make the PM- 7543 a superior pin-compatible second-source to the industry standard AD7543.

The rising or falling edge (user selected) ofthe strobe inputs are used to clock serial data (present at the SRI pin) into the input shift register. When the shift register's data has been updated. the new data word is transferred to the DAC register with use of the LOAD inputs.

Separate LOAD control inputs allow simultaneous output updating of multiple DACs. An asynchronous CLEAR input resets the DAC register without altering the data in the input register.

Improved linearity and gain error performance may permit reduced circuit parts count through the elimination of trimming components. Fast interface timing may reduce timing design considerations while minimizing microprocessor wait states. The PM-7543 is available in standard plast icand CerDIP packages that are compatible with autoinsertion equipment. For an even smaller package, consider the DAC- 8043, available in an a-pin mini-DIP.

CerDIP and epoxy devices are available in the extended industrial temperature range of -40°C to +B5°C.
