Description
13
AIN3
Analog Input. It can be configured as the positive input of a fully differential input pair when used with
AIN4 or as a pseudo differential input when used with AINCOM.
14
AIN4
Analog Input. It can be configured as the negative input of a fully differential input pair when used with
AIN3 or as a pseudo differential input when used with AINCOM.
15
REFIN1(+)
Positive Reference Input. An external reference can be applied between REFIN1(+) and REFIN1().
REFIN1(+) can lie anywhere between AVDD and AGND + 1 V. The nominal reference voltage, (REFIN1(+)
REFIN1()), is AVDD, but the part functions with a reference from 1 V to AVDD.
16
REFIN1()
Negative Reference Input. This reference input can lie anywhere between AGND and AVDD 1 V.
17
BPDSW
Bridge Power-Down Switch to AGND.
18
AGND
Analog Ground Reference Point.
19
DGND
Digital Ground Reference Point.
20
AVDD
Analog Supply Voltage, 4.75 V to 5.25 V. AVDD is independent of DVDD.
21
DVDD
Digital Supply Voltage, 2.7 V to 5.25 V. DVDD is independent of AVDD.
22
SYNC
Logic input that allows for synchronization of the digital filters and analog modulators when using
multiple AD7190 devices. While SYNC is low, the nodes of the digital filter, the filter control logic, and the
calibration control logic are reset and the analog modulator is held in its reset state. SYNC does not affect
the digital interface but does reset RDY to a high state if it is low. SYNC has a pull-up resistor internally to
DVDD.
23
DOUT/RDY
Serial Data Output/Data Ready Output. DOUT/RDYserves a dual purpose. It functions as a serial data
output pin to access the output shift register of the ADC. The output shift register can contain data from
any of the on-chip data or control registers. In addition, DOUT/RDY operates as a data ready pin, going low
to indicate the completion of a conversion. If the data is not read after the conversion, the pin goes high
before the next update occurs. The DOUT/RDY falling edge can be used as an interrupt to a processor,
indicating that valid data is available. With an external serial clock, the data can be read using the
DOUT/RDY pin. With CS low, the data/control word information is placed on the DOUT/RDY pin on
the SCLK falling edge and is valid on the SCLK rising edge.
24
DIN
Serial Data Input to the Input Shift Register on the ADC. Data in this shift register is transferred to the
control registers in the ADC, with the register selection bits of the communications register identifying the
appropriate register.
