illustrate

ADC081C021 is a low-power, monolithic, 8-bit Analog to digital Converters (ADCs) that operate from 2.7 to 5.5V power supplies. The converter is based on successive approximation register structure with internal track and hold circuitry and can handle input frequencies up to 11MHz. “ ADC081C021 Operate from a single supply, which is also used as a reference. The device has: I 2 C compatible Serial interface, operates in all three speed modes, including high-speed mode (3.4MHz).

The ADC's alarm function provides an interrupt when an analog input is activated, violating a programmable upper or lower limit value. The device has an automatic conversion mode that frees up the controller and I 2 C interface. In this mode, the ADC continuously monitors the analog input for "range" conditions and provides an interrupt if the measured voltage is out of range.

ADC081C021 come in two packages: a small TSOT-6 package with alarm output, an MSOP-8 package with alarm output and 2 address selection input packages. “ ADC081C027 In a small TSOT-6 package with an address selection input. “ ADC081C027 Three pin selectable addresses are available, while the ADC081C021 with the MSOP-8 version offers 9 pin selectable addresses. Pin-compatible alternatives: TSOT-6 options provide additional address options.

, the power consumption of a +3 V or +5 V power supply is 0.26mW and 0.78mW, respectively. Automatic power-off function reduces power consumption to less than 1μW without conversion. Guaranteed to operate in industrial temperatures ranging from -40°C to +105°C. Its low power consumption and small package make this series of ADCs an excellent choice for battery-powered devices.

“ ADC081C021 and ADC081C027 Pin-compatible ADC that also offers part of a 10-family and 12-bit resolution. For 10-bit ADCs see: ADC101C021 and ADC101C027 。 For 12-bit ADCs, see: ADC121C021 and ADC121C027 。
