ADS7816E/250

Analog To Digital Converters (ADC) Overview

The ADS7816E/250 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-channel input with differential or single-ended capability and operates on a 4.5 V to 5.25 V supply. The device supports a sampling rate of 200 kS/s via a 3-wire serial interface. Key performance metrics include a signal-to-noise-and-distortion ratio (SINAD) of 72 dB, differential nonlinearity (DNL) of +/- 2 LSB, and integral nonlinearity (INL) of +/- 2 LSB. Power consumption is rated at 1.9 mW. It utilizes an external reference and is housed in an 8-VSSOP package, operating within a temperature range of -40°C to +85°C.

• Industrial process control systems
• Data acquisition modules

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix E/250 against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Check for any recent product change notices regarding packaging or material compliance. Ensure the external reference voltage source meets the required accuracy specifications for the target application.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 200 kS/s sampling rate are sufficient for the application. It is appropriate for designs requiring a 3-wire interface rather than standard SPI. Consider the need for an external reference voltage, as this model does not include an internal one unlike some family members. Evaluate the power budget against the 1.9 mW consumption figure.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7816 series of micro-power ADCs from Texas Instruments. It shares the same core architecture and pinout with variants like the ADS7816E/1K5 but differs in packaging quantity. The series is designed for applications balancing precision and power efficiency in a compact surface-mount package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7816E/250 may be discontinued; verify status with the manufacturer. Potential substitutes within the same family include the ADS7816E/1K5 or other 12-bit SAR ADCs with similar 3-wire interfaces and 200 kS/s speeds, provided external reference compatibility is maintained.
