into one via DIN, SCLK, and FSYNC. The AD7834 has five
dedicated package address pins, PA0 to PA4, that can be wired
to AGND or VCC to permit up to 32 AD7834s to be individually
addressed in a multipackage application. FEATURES

AD7834—28-lead SOIC and PDIP
AD7835—44-lead MQFP and PLCC The AD7835 can accept either 14-bit parallel loading or doublebyte loading, where right-justified data is loaded in one 8-bit
byte and one 6-bit byte. Data is loaded from the external bus
into one of the input latches under the control of the WR, CS,
BYSHF, and DAC channel address pins, A0 to A2. GENERAL DESCRIPTION With each device, the LDAC signal is used to update all four …
