Description
28, 30
DOUTB,
DOUTA
Serial Data Outputs. The data output is supplied to each pin as a serial data stream. The bits are clocked out on the
falling edge of the SCLK input and 14 SCLKs are required to access the data. The data simultaneously appears on
both pins from the simultaneous conversions of both ADCs. The data stream consists of two leading zeros
followed by the 12 bits of conversion data. The data is provided MSB first. If CS is held low for 16 SCLK cycles rather
than 14, then two trailing zeros will appear after the 12 bits of data. If CS is held low for a further 16 SCLK cycles on
either DOUTA or DOUTB, the data from the other ADC follows on the DOUT pin. This allows data from a simultaneous
conversion on both ADCs to be gathered in serial format on either DOUTA or DOUTB using only one serial port. See
the
section.
31
VDRIVE
Logic Power Supply Input. The voltage supplied at this pin determines at what voltage the interface operates. This
pin should be decoupled to DGND. The voltage at this pin may be different than that at AVDD and DVDD but should
never exceed either by more than 0.3 V.
32
DVDD
Digital Supply Voltage, 2.7 V to 5.25 V. This is the supply voltage for all digital circuitry on the AD7266. The DVDD
and AVDD voltages should ideally be at the same potential and must not be more than 0.3 V apart even on a
transient basis. This supply should be decoupled to DGND.
EPAD
Exposed Pad. The exposed metal paddle on the bottom of the LFCSP package should be soldered to PCB ground.
