Description
General part information
ADC081C021 Series
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.
