PIN DESCRIPTIONS

Pin Name

Pin Description

Analog Inputs to the MUX (multiplexer). A channel input is selected by the address information at the DI pin, which

is loaded on the rising edge of SCLK into the address register (See Table 2, Table 3, and Table 4). The voltage

CH0 thru CH7

applied to these inputs should not exceed VA+ or go below VA- or below GND. Exceeding this range on an

unselected channel may corrupt the reading of a selected channel.

COM

Analog input pin that is used as a pseudo ground when the analog multiplexer is single-ended.

MUXOUT1

Multiplexer Output pins. If the multiplexer is used, these pins should be connected to the A/DIN pins, directly or

MUXOUT2

through an amplifier and/of filter.

Converter Input pins. MUXOUT1 is usually tied to A/DIN1. MUXOUT2 is usually tied to A/DIN2. If external circuitry

A/DIN1

is placed between MUXOUT1 and A/DIN1, or MUXOUT2 and A/DIN2, it may be necessary to protect these pins

A/DIN2

against voltage overload.. The voltage at these pins should not exceed VA

+ or go below AGND (see Figure 60).

Data Output pin. This pin is an active push/pull output when CS is low. When CS is high, this output is TRI-STATE.

The conversion result (D0–D12) and converter status data are clocked out by the falling edge of SCLK on this pin.

DO

The word length and format of this result can vary (see Table 1). The word length and format are controlled by the

data shifted into the multiplexer address and mode select register (see Table 5).

Serial Data input pin. The data applied to this pin is shifted by the rising edge of SCLK into the multiplexer address

DI

and mode select register. Table 2 through Table 5 show the assignment of the multiplexer address and the mode

select data.

This pin is an active push/pull output which indicates the status of the ADC12030/2/4/8. A logic low on this pin

EOC

indicates that the ADC is busy with a conversion, Auto Calibration, Auto Zero or power down cycle. The rising edge

of EOC signals the end of one of these cycles.

A logic low is required at this pin to program any mode or to change the ADC's configuration as listed in Mode

Programming Table 5. When this pin is high, the ADC is placed in the read data only mode. While in the read data

only mode, bringing CS low and pulsing SCLK will only clock out the data stored in the ADCs output shift register.

CONV

The data on DI will be neglected. A new conversion will not be started and the ADC will remain in the mode and/or

configuration previously programmed. Read data only cannot be performed while a conversion, Auto Cal or Auto

Zero are in progress.
