GENERAL DESCRIPTION
The AD7834 and AD7835 contain four 14-bit DACs on one monolithic chip. The AD7834 and AD7835 have output
voltages in the range ±8.192 V with a maximum span of 14 V.
The AD7834 is a serial input device. Data is loaded in 16-bit format from the external serial bus, MSB first after two leading 0s,
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 perm...
