ADS932E/2K

Analog To Digital Converters (ADC) Overview

The ADS932E/2K is a 16-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a successive approximation register (SAR) architecture with an internal sample-and-hold amplifier. The device supports dual supply voltages, operating from 2.7V to 3.6V for both analog and digital domains, or a single 5V supply. It offers a maximum sampling rate of 100 kSPS and includes a serial peripheral interface (SPI) compatible with standard modes. The input configuration supports both differential and single-ended signals, providing flexibility in system design. The component is housed in a 16-lead SSOP package and is rated for operation over an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '/2K' indicates reel packaging when ordering. Confirm the voltage supply requirements match the target application's power rails. Ensure the SPI timing parameters align with the host microcontroller's clock speeds. Check for RoHS compliance status if required by regulatory standards.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring 16-bit accuracy at moderate speeds. Consider the 16-SSOP package size for PCB layout constraints. Evaluate the need for differential versus single-ended inputs to simplify front-end circuitry. Compare power consumption against other SAR ADCs if battery life is critical.

Analog To Digital Converters (ADC) Part Context

The ADS932 belongs to Texas Instruments' family of low-power, 16-bit SAR ADCs. It is designed for general-purpose data acquisition tasks where precision and low power are balanced. The '/2K' designation typically refers to the tape and reel quantity for manufacturing automation.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements may be limited. Verify compatibility with ADS932 variants such as ADS932A or ADS932B for potential performance upgrades. Check for newer generations like the ADS9326 if higher speed or additional channels are needed.
