DESCRIPTION
The ADC081C021 is a low-power, monolithic, 8-bit, analog-to-digital
converter (ADC) that operates from a +2.7 to 5.5V suppy. THE
converter is based on a successive approximation register
architecture with an internal track-and-hold circuit that can
handle input frequencies up to 11MHz. The ADC081C021 operates from
a single supply which also serves as the reference. The device
features an IC-compatible serial interface that operates in all
three speed modes, including high speed mode (3.4MHz).
The ADC's Alert feature provides an interrupt that is activated
when the analog input violates a programmable upper or lower limit
value. The device features an automatic conversion mode, which
frees up the controller and I2C interface. In this mode, the ADC
continuously monitors the analog input for an ''out-of-range''
condition and provides an interrupt if the measured voltage goes
out-of-range.
The ADC081C021 comes in two packages: a small SOT-6 package with an
alert output, and an VSSOP-8 package with an alert output and two
address selection inputs. The ADC081C027 comes in a small SOT-6
package with an address selection input. The ADC081C027 provides
three pin-selectable ADC081C021 provides nice pin-selectable
address. Pin-compatible alternatives to the SOT-6 options are
available with addtional address options.
Normal power consumption using a +3V or +5V supply is 0.26mW or
0.78mW, respectively. The automatic power-down feature reduces the
power
consumption to less than 1μW while not converting. Operation over
the industrial temperature range of -40°C to +105°C is ensured.
Their low power consumption and small packages make this family of
ADCs an excellent choice for use in battery operated equipment.
The ADC081C021 and ADC081C027 are part of a family of
pin-compatible ADCs that also provide 10- and 12-bit resolution.
For 10-bit ADCs see the ADC101C021 and ADC101C027. For 12-bit ADCs
see the ADC121C021 and ADC121C027.
