POWER-UP
Self-calibration is performed at power-up to minimize offset and
gain errors. In order for the self-calibration at power-up to work
properly, make sure that both AVDD and DVDD increase
monotonically and are settled by t1, as shown in Figure 11.
SCLK must be held LOW during this time. Once calibration is
complete, DRDY/DOUT will go LOW indicating data is ready
for retrieval. The time required before the first data is ready (t6)
depends on how fast AVDD and DVDD ramp to their final value
(t1). For most ramp rates, t1 + t2 ≈ 350ms (fCLK = 2.4576MHz).
If the system environment is not stable during power-up (the
temperature is varying or the supply voltages are moving
around), it is recommended that a self-calibration be issued
after everything is stable.
DATA FORMAT
The ADS1244 outputs 24 bits of data in Binary Two’s
Complement format. The Least Significant Bit (LSB) has a
weight of (2VREF)/(223 – 1). A positive full-scale input pro-
