ADC122S051CIMMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC122S051CIMMX/NOPB is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. The device supports variable sampling rates between 200 ksps and 500 ksps, with typical power consumption of 3.0 mW at 3 V and 10 mW at 5 V. It features an SNR of 72.5 dB and utilizes a compact 10-pin VSSOP package. The component is specified for industrial temperatures from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIMMX' against the manufacturer's official documentation to confirm pinout compatibility and package dimensions. Ensure the operating environment remains within the specified -40°C to +85°C temperature range. Confirm that the system clock frequency aligns with the supported SCLK range of 3.2 MHz to 8 MHz for proper interface synchronization.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel solution is required with moderate resolution and variable throughput. Compare power dissipation requirements against the 3.0 mW typical value at 3 V. Evaluate the need for serial interface flexibility versus parallel alternatives. Consider the 10-VSSOP footprint constraints during PCB layout planning.
