DESCRIPTION

The ADC081C021 is a low-power, monolithic, 8-bit,

analog-to-digital converter (ADC) that operates from a

+2.7 to 5.5V supply. 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 I2C-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 addresses while the VSSOP-8 version of the

ADC081C021 provides nine pin-selectable

addresses. Pin-compatible alternatives to the SOT-6

options are available with additional 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.
