The MP7612 is equipped with a serial data (3-wire standard)
μ
-processor logic interface to reduce pin count, package size,
and board wire (space). If the LD signal is high, the CLK signal
loads the digital input bits (SDI) into the shift register (4 bits ad-
dress A3 to A0 plus 12 bits data DB11 to DB0 for the MP7612).
The LD signal going low loads the data into the selected DAC.
The LD signal going low also disables the serial data (SDI), out-
put (SDO 3-stated) and the CLK input. This design tremen-
dously reduces digital noise and glitch transients into the DACs
due to free running CLK and SDI. Note also that the preset sig-
nal (RST) resets all analog outputs to 0 volt regardless of digital
inputs.
