DEVICE CONFIGURATION
ADS62P4X can be configured independently using either parallel interface control or serial interface
programming.
USING PARALLEL INTERFACE CONTROL ONLY
To control the device using the parallel interface, keep RESET tied to high (AVDD). Pins SEN, SCLK, CTRL1,
CTRL2 and CTRL3 can be used to directly control certain modes of the ADC. After power-up, the device will
In this mode, SEN and SCLK function as parallel analog control pins, which can be configured using a simple
resistor divider (Figure 5, using resistors
<= 10% tolerance
). Table 3 has a brief description of the modes
controlled by the parallel pins. SDATA has no parallel function and can be kept low.

USING SERIAL INTERFACE PROGRAMMING ONLY
To program the device using the serial interface, keep RESET low. Pins SEN, SDATA, and SCLK function as
serial interface digital pins and are used to access the internal registers of ADC. The registers must first be reset
to their default values either by applying a pulse on RESET pin or by setting bit
<RST> = 1. After reset, the
RESET pin must be kept low.
The serial interface section describes the register programming and register reset in more detail. Since the
parallel pins (CTRL1, CTRL2, CTRL3) are not used in this mode, they must be tied to ground.
USING BOTH SERIAL INTERFACE and PARALLEL CONTROLS
For increased flexibility, a combination of serial interface registers and parallel pin controls (CTRL1 to CTRL3)
can also be used to configure the device. To allow this, keep RESET low.
The parallel interface control pins CTRL1 to CTRL3 are available. After power-up, the device will automatically
get configured as per the voltage settings on these pins (Table 6).
SEN, SDATA, and SCLK function as serial interface digital pins and are used to access the internal registers of
ADC. The registers must first be reset to their default values either by applying a pulse on RESET pin or by
setting bit
<RST> = 1. After reset, the RESET pin must be kept low. The serial interface section describes the
register programming and register reset in more detail.
Since the power down modes can be controlled using both the parallel pins and serial registers, the priority
between the two is determined by
<OVRD> bit. When <OVRD> bit = 0, pins CTRL1 to CTRL3 control the power
down modes. With
<OVRD> = 1, register bits <POWER DOWN> control these modes, over-riding the pin
settings.
