DESCRIPTION
Pins OP[13:0] form a Hi-Z digital bi-directional bus. There are several modes:
Hi-Z: when OEB = 1.
14-bit output: 14-bit data is output on OP[13:0].
8-bit multiplexed output: data is output on OP[13:6] at 2
ADC conversion rate.
7-bit multiplexed output: data is output on OP[13:6] at 2
ADC conversion rate.
4-bit multiplexed output: data is output on OP[13:10] at 4
ADC conversion rate.
See Output Formats section in Device Description for further details.
Input 8-bit: control data is input on OP[13:6] in parallel mode when SCK/RNW = 0,
and SEN/STB = 0.
Output 8-bit: register read back data is output in parallel on OP[13:6] when
SCK/RNW = 1, and SEN/STB = 0, or in serial on pin SDO when SEN/STB = 1.
Digital I/O supply (3.3V/5V).
Digital ground (0V).
See pins 21 to 23 for details.

Digital I/O supply (3.3V/5V).
Digital ground (0V).
See pins 21 to 23 for details.
If the device has been configured to use the serial interface, pin OP[13]/SDO may
be used to output register read-back data when OEB = 0 and SEN has been
pulsed high.
See Serial Interface sections in Device Description for further details.
Digital ground (0V).
No connection.
Reset input, active low. This signal forces a reset of all internal registers and selects
whether the serial or parallel control interface is used. See pin SEN/STB.
Analogue supply (5V).
Analogue supply (5V).
Analogue ground (0V).
Analogue ground (0V).
Lower reference voltage. This pin must be capacitively decoupled to AGND.
