Data Sheet
TIMING CHARACTERISTICS
AVDD = 4.5 V to 16.5 V; AVSS = −4.5 V to −16.5 V, or AVSS = 0 V; GND = 0 V; REFIN = 2.5 V external; DVCC = 2.7 V to 5.5 V; RLOAD = 2 kΩ;
CLOAD = 200 pF; all specifications TMIN to TMAX, unless otherwise noted.

Description
SCLK cycle time
SCLK high time
SCLK low time
SYNC falling edge to SCLK falling edge setup time
SCLK falling edge to SYNC rising edge
Minimum SYNC high time (write mode)
Data setup time
Data hold time
LDAC falling edge to SYNC falling edge
SYNC rising edge to LDAC falling edge
LDAC pulse width low
DAC output settling time
CLR pulse width low
CLR pulse activation time
SYNC rising edge to SCLK rising edge
SCLK rising edge to SDO valid (CL SDO5 = 15 pF)
Minimum SYNC high time (readback/daisy-chain mode)
1 Guaranteed by characterization; not production tested.
2 All input signals are specified with tR = tF = 5 ns (10% to 90% of DVCC) and timed from a voltage level of 1.2 V.
3 See Figure 2, Figure 3, and Figure 4.
4 Daisy-chain and readback mode.
5 CL SDO = capacitive load on SDO output.
