Description
Positive Analog Power Supply; +9 V to +16.5 V for specified performance. These pins
should be decoupled with 0.1 μF ceramic capacitors and 10 μF capacitors.
Negative Analog Power Supply; −16.5 V to −8 V for specified performance. These pins
should be decoupled with 0.1 μF ceramic capacitors and 10 μF capacitors.
Ground for All Digital Circuitry. Both DGND pins should be connected to the DGND plane.
Logic Power Supply; 2.5 V to 5.5 V. These pins should be decoupled with 0.1 μF ceramic
capacitors and 10 μF capacitors.
Active Low Input. This is the frame synchronization signal for the serial interface. See the
Timing Characteristics section for more details.
Serial Clock Input. Data is clocked into the shift register on the falling edge of SCLK. This
pin operates at clock speeds up to 50 MHz. See the Timing Characteristics section for
more details.
Serial Data Input. Data must be valid on the falling edge of SCLK. See the Timing
Characteristics section for more details.
Serial Data Output for SPI Interface. CMOS output. SDO can be used for readback. Data is
clocked out on SDO on the rising edge of SCLK and is valid on the falling edge of SCLK.
Ground for All Analog Circuitry. The AGND pin should be connected to the AGND plane.
Load DAC Logic Input (Active Low).
Asynchronous Clear Input (Level Sensitive, Active Low). See the Clear Function section for
more information.
The lead-free chip scale package (LFCSP) has an exposed paddle on the underside. The
paddle should be connected to V
