Product details

12-bit SAR ADC, 1 MSPS, 4-channel single-ended

The Texas Instruments ADC124S101CIMM is a 12-bit successive-approximation-register (SAR) ADC that samples four single-ended inputs at 1 MSPS through an internal multiplexer. The SPI/DSP-compatible serial interface streams conversion results on a single data line, keeping the pin count to ten in the 10-VSSOP package.

Supply range and analog front-end flexibility

The reference is derived from the supply itself (Reference Type: Supply), meaning the full-scale range tracks the supply voltage — a 5 V rail gives a 0-5 V input span, while a 3.3 V rail scales it to 0-3.3 V. The 1:1 S/H-to-ADC ratio and SAR architecture deliver a clean sample-and-hold per channel without pipeline latency — useful for multiplexed sensor arrays where each channel needs a fresh conversion on demand.

Note that the RoHS compliance status is marked non-compliant, so this part contains lead — verify your assembly's exemption status if the board must meet full RoHS 2/3 exemption-free requirements.

Frequently asked questions

What is the closest functional second-source for ADC124S101CIMM?

The ADC124S021CIMM/NOPB is the closest functional peer — same 12-bit SAR architecture, same 4-channel single-ended input stage, same 10-VSSOP package, and same SPI/DSP interface. The main difference is sampling rate: the ADC124S101 runs at 1 MSPS, while the ADC124S021 runs at 200 kSPS. The pinout is identical, so it drops into the same PCB footprint without rewiring, though the slower throughput may limit the application.

What compliance documentation does Texas Instruments provide for ADC124S101CIMM?

Texas Instruments provides a datasheet and the RoHS compliance status (non-compliant). The RoHS non-compliance means the device contains lead — check your local exemption rules before specifying.
