Pin Function Descriptions1 Pin No. Type2 Mnemonic Description 1, 37, 38, 48 P AVCC Analog Supply Voltage, 4.75 V to 5.25 V. This supply voltage is applied to the internal front-end amplifiers and to the ADC core. Decouple these supply pins to AGND. 2, 3, 4, 5, 26, 35, 40, 41, 47 GND AGND Analog Ground. These pins are the ground reference points for all analog circuitry on the AD7605-4. Refer all analog input signals and external reference signals to these pins. Connect all AGND pins to the AGND plane of a system. 6 DI PAR/SER/ BYTE SEL Parallel Interface Selection Input (PAR). This pin is a logic input. If this pin is tied to a logic low, the parallel interface is selected. Parallel byte interface mode is selected when this pin is logic high and DB15/BYTE SEL is logic high (see Table 8). Serial Interface Selection Input (SER). If this pin is tied to a logic high, the serial interface is selected. In serial mode, the RD/SCLK pin functions as the serial clock input. The DB7/DOUTA pin and the DB8/DOUTB pin function as serial data outputs. When the serial interface is selected, tie the parallel output data bit pins (Pin 16 to Pin 22, and Pin 27 to Pin 33) to ground. Parallel Byte Interface Selection Input (BYTE SEL). In byte mode, DB15/BYTE SEL, in conjunction with PAR/SER/BYTE SEL, selects the parallel byte mode of operation (see Table 8). DB14/HBEN functions as the high byte enable (HBEN) pin. DB7 to DB0 transfer the 16-bit conversion results in two RD/SCLK operations, with DB0 as the LSB of the data transfers. 7 DI STBY Standby Mode Input. This pin places the AD7605-4 into one of two power-down modes: standby mode or shutdown mode. The power-down mode entered depends on the state of the RANGE pin, as shown in Table 7. When in standby mode, all circuitry, except the on-chip reference, regulators, and regulator buffers, is powered down. When in shutdown mode, all circuitry is powered down. 8 DI RANGE Analog Input Range Selection. RANGE is a logic input. The polarity on this pin determines the input range of the analog input channels. If this pin is tied to a logic high, the analog input range is ±10 V for all channels. If this pin is tied to a logic low, the analog input range is ±5 V for all channels. A logic change on this pin has an immediate effect on the analog input range. Changing this pin during a conversion is not recommended for fast throughput rate applications. See the Analog Input section for more information.
