ADC141S628QIMM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC141S628QIMM/NOPB is a dual-channel, 14-bit successive approximation register (SAR) analog-to-digital converter (ADC) designed for automotive applications. It supports sampling rates up to 1 MSPS per channel with a total throughput of 2 MSPS. The device operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. It features a serial peripheral interface (SPI) compatible with standard modes. Key performance metrics include a signal-to-noise ratio (SNR) of approximately 80 dB at 1 MSPS and an input bandwidth of 35 MHz. The component is housed in an 8-pin VSSOP package and is qualified under AEC-Q100 standards for operation across a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free composition and RoHS compliance as per Texas Instruments documentation. Confirm the 'Q' prefix denotes automotive grade qualification before integration into safety-critical designs. Ensure the VSSOP-8 package dimensions match the target PCB footprint. Check for any recent lifecycle status changes such as NRND or obsolescence notices directly from the manufacturer's official product page.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 14-bit resolution is required alongside high-speed sampling capabilities. Compare against single-channel alternatives if only one input is needed to reduce cost. Consider the 35 MHz input bandwidth for signal fidelity requirements. Evaluate power constraints against the specified operating voltage range. Verify SPI compatibility with the host microcontroller's available interfaces.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC141x family of high-speed, low-power SAR ADCs from Texas Instruments. The family shares similar architectural features but varies in channel count and resolution. The ADC141S628 specifically targets applications requiring two independent channels with 14-bit accuracy. It complements other TI data converters by offering integrated reference and clock options in related variants.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same package and pinout include the ADC141S621 and ADC141S626, though resolution and speed may differ. Cross-family replacements like the ADS121 series offer different interface types. Verify electrical parameters and pin compatibility before swapping components. Consult the TI replacement guide for validated alternatives.
