Rev. 4.01
The MP7610 is equipped witha serialdata (3-wire standard)
μ
-processor logic interface to reduce pin count, package size,
and board wire (space). Ifthe LD signal is high, the CLK signal
loads the digital inputbits (SDI) into the shiftregister(4 bits ad-
dress A3toA0plus 14bits dataD13toD0fortheMP7610). The
LD signal going low loads the data into the selected DAC. The
LD signal going low also disables the serial data (SDI), output
(SDO tri-stated) and the CLK input. This design tremendously
reduces digital noise and glitch transients into the DACs due to
free running CLK and SDI. Note also that the preset signal
(RST) resets all analog outputs to 0 voltregardless ofdigitalin-
puts.
