ADC121C027CIMK/NOPB

Analog To Digital Converters (ADC) Overview

The ADC121C027CIMK/NOPB is a low-power, monolithic, 12-bit analog-to-digital converter manufactured by Texas Instruments. It operates from a single +2.7V to +5.5V supply and utilizes a successive approximation register architecture with an internal track-and-hold circuit capable of handling input frequencies up to 11MHz. The device features an I2C-compatible serial interface supporting standard (100kHz), fast (400kHz), and high-speed (3.4MHz) modes. It provides three pin-selectable chip addresses for multi-device systems and includes an automatic power-down mode that reduces consumption to less than 1µW during idle periods.

• I2C-compatible 2-wire interface supporting standard, fast, and high-speed communication modes
• Three pin-selectable slave addresses for flexible bus configuration
• Automatic power-down mode significantly reduces power consumption when not converting
• Small 6-pin SOT surface-mount package design

Analog To Digital Converters (ADC) Applications

• System monitoring
• Peak detection
• Portable instruments
• Medical instruments
• Test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure the selected component matches the required address selection pins and interface voltage levels for the target system design.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring a compact 12-bit ADC with minimal external components. Consider the three available address options if multiple converters are needed on a single I2C bus. Verify that the maximum throughput rate meets the signal sampling requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC121C family of low-power, 12-bit analog-to-digital converters. It shares pin compatibility with other resolutions in the series, such as the 8-bit ADC081C027 and 10-bit ADC101C027, allowing for potential resolution upgrades without changing the PCB layout.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the ADC101C027 and ADC081C027 for lower resolution needs. For automotive applications, verify if the AEC-Q100 qualified ADC121C021Q is required instead.
