ADS7816E/250G4

Analog To Digital Converters (ADC) Overview

The ADS7816E/250G4 is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-channel input supporting both differential and single-ended configurations with a sampling rate of 200 kS/s. The device operates on a 4.5 V to 5.25 V supply for both analog and digital domains, consuming 1.9 mW of power. It utilizes an external reference and communicates via a 3-wire interface. Key performance metrics include a signal-to-noise ratio (SNR) of 72 dB, differential nonlinearity (DNL) of +/- 2 LSB, and integral nonlinearity (INL) of +/- 2 LSB. It is housed in an 8-pin VSSOP package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance when sourcing. Confirm the package type matches the design requirements as it is supplied in VSSOP-8. Ensure the external reference voltage matches the ADC's input specifications for optimal linearity. Check moisture sensitivity levels for proper storage and handling procedures during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit conversion is required at speeds up to 200 kS/s. It is appropriate for designs needing low power dissipation under 2 mW. Consider the external reference requirement if system noise budgets are tight. Compare against the ADS7816E/250 for functional equivalence regarding pinout and electrical characteristics.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7816 series of micro-power sampling ADCs from Texas Instruments. It shares architectural similarities with other SAR converters in the family but is distinct in its 200 kS/s speed grade and single-channel configuration. The G4 suffix typically denotes environmental compliance standards defined by the manufacturer.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7816E/250 is a direct functional equivalent within the same product family. Verify pin compatibility and electrical parameter alignment before substitution.
