Reference
The devices operate with either a +2.5V internal
bandgap reference or an external reference source
between +2.3V and +2.7V applied at REFIO. Bypass
REFIO and each REF_ to AGND with a 1μF capacitor.
The reference voltage sets the positive and negative
full-scale voltage according to the following formula:
±FS = ±0.88 VREFIO
The reference voltage at REFIO (external or internal) is
individually buffered to generate the reference voltages
at REF0 to REF3 (see Figure 6.) These independent
buffers minimize the potential for crosstalk between
each of the internal ADCs.
Serial Interface
The devices’ interface is fully compatible with SPI/DSP
standard serial interfaces (compatible with SPI modes
CPOL = 1, CPHA = 0). The serial interface provides
access to four on-chip registers: Sampling Instant
Control register (32 bits), Data Rate Control register (16
bits), Configuration register (8 bits), and Data register
(96 bits). All serial-interface commands begin with a
command byte, which addresses a specific register,
followed by data bytes with a data length that depends
on the specific register addressed and the number of
devices cascaded (see Figures 7, 8, and the
Registers
section).
The serial interface consists of eight signals: CS,
SCLK, DIN, DOUT, CASCIN, CASCOUT, DRDYIN,
and DRDYOUT. CASCIN, CASCOUT, DRDYIN, and
DRDYOUT are used for daisy chaining multiple devices
together. See the
Multiple Device Connection section
for details on how to connect CASCIN, CASCOUT,
+2.5V
