Device Address Select Pin 0. This pin determines the LSB of the device address
required to communicate using the 2-wire interface. The A0 pin has an on-chip pull-down resistor.
Device Address Select Pin 1. This pin determines the intermediate bit of the device address re-
quired to communicate using the 2-wire interface. The A1 pin has an on-chip pull-down resistor.
Device Address Select Pin 2. This pin determines the MSB of the device address required to
communicate using the 2-wire interface. The A2 pin has an on-chip pull-down resistor.
Supply Voltage.
Write Protect Control Pin. This pin is a CMOS compatible input. When LOW, Write Protection
is enabled preventing any “Write” operation. When HIGH, various areas of the memory can be
protected using the Block Lock bits BL1 and BL0. The WP pin has an on-chip pull-down resistor,
which enables the Write Protection when this pin is left floating.
Serial Clock. This is a TTL compatible input pin. This input is the 2-wire interface clock controlling
data input and output at the SDA pin.
Serial Data. This pin is the 2-wire interface data into or out of the device. It is TTL
compatible when used as an input, and it is Open Drain when used as an output. This pin requires
an external pull up resistor.
Current Generator 1 Output. This pin sinks or sources current. The magnitude and direction of
the current is fully programmable and adaptive. The resolution is 8 bits.
Current Programming Resistor 1. A resistor between this pin and Vss can set the maximum
output current available at pin I1. If no resistor is used, the maximum current must be selected
using control register bits.
Current Programming Resistor 2. A resistor between this pin and Vss can set the maximum
output current available at pin I2. If no resistor is used, the maximum current must be selected
using control register bits.
Ground.
Sensor Voltage Input. This voltage input may be used to drive the input of the on-chip A/D con-
verter.
Reference Voltage Input or Output. This pin can be configured as either an Input or an Output.
As an Input, the voltage at this pin is provided by an external source. As an Output, the voltage
at this pin is a buffered output voltage of the on-chip bandgap reference circuit. In both cases, the
voltage at this pin is the reference for the A/D
converter and the two D/A converters.
Current Generator 2 Output. This pin sinks or sources current. The magnitude and direction of
the current is fully programmable and adaptive. The resolution is 8 bits.
