Overview

·Very small TSOT-6 and MSOP-8 packages ·±8kV HBM ESD protection(SDA,SCL) APPLICATIONS ·System Monitoring ·Peak Detection ·Portable Instruments ·Medical Instruments ·Test Equipment DESCRIPTION The ADC081C021CIMM/NOPB 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 ADC081C021CIMM/NOPB operates from a single supply which also serves as the reference. The device features an IPC-compatible serial interface that operates in alil 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 programmableupper or lower limit value. The device features an automatic conversion mode, which frees up the controller and IPC interface. In this mode, the ADC continuously monitors the analog input for an "out-of-range"condition and provides an interupt if the measured voltage goes out-of-range. The ADC081C021CIMM/NOPB comes in two packages:a small TSOT-6 package with an alert output, and an MSOP-8 package with an alert output and two address selection inputs. The ADC081C027 comes in a small TSOT-6 package with an address selection input. The ADC081C027 provides three pin-selectable addresses while the MSOP-8 version of the ADC081C021CIMM/NOPB provides nine pin-selectable addresses. Pin-compatible alternatives to the TSOT-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 iess than 1uW while not converting. Operation over the industrial temperature range of -40℃ to +105C is guaranteed. Their low power consumption and small packages make this family of ADCs an excellent choice for use in battery operated equipment. The ADC081C021CIMM/NOPB 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.
