Description
General part information
ADC121C027 Series
These converters are low-power, monolithic, 12-bit, analog-to-digital converters (ADCs) that operates from a +2.7 to 5.5V supply. The converter is based upon a successive approximation register architecture with an internal track-and-hold circuit that can handle input frequencies up to 11MHz. These converters operate 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 ADC121C021'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 ADC121C021 comes in two packages: a small 6-pin SOT package with an alert output, and an 8-pin VSSOP package with an alert output and two address selection inputs. The ADC121C021Q is available in a 6-pin SOT package. The ADC121C027 comes in a small 6-pin SOT package with an address selection input. The ADC121C027 provides three pin-selectable addresses while the 8-pin VSSOP version of the ADC121C021 provides nine pin-selectable addresses. Pin-compatible alternatives to the 6-pin SOT options are available with additional address options.
