ADS7229IPWRG4

Analog To Digital Converters (ADC) Overview

The ADS7229IPWRG4 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 1 MS/s and supports single-ended inputs. The device features an SPI-compatible serial interface and is housed in a TSSOP-16 package. It requires an external voltage reference and offers low power consumption of 13.7 mW at full speed. Key performance metrics include a signal-to-noise ratio (SNR) of 73.9 dB, integral nonlinearity (INL) of +/- 0.5 LSB, and differential nonlinearity (DNL) of +/- 0.5 LSB. It functions within an analog supply range of 2.7 V to 5.5 V and a digital supply range of 1.65 V to 5.5 V, with an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Single-channel input with daisy-chainable capability for multi-device systems
• SPI-compatible serial interface supporting standard communication protocols

Analog To Digital Converters (ADC) Applications

• Portable medical instrumentation requiring low power and moderate resolution
• Industrial process control systems with single-ended sensor inputs
• Data acquisition modules for environmental monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's current datasheet to confirm RoHS compliance status and any minor pinout or electrical variations compared to the base ADS7229 model. Ensure the ordering information matches the exact package type and temperature grade required for your design specifications before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is sufficient for the application. Consider the ADS7229 series if low power consumption and a small TSSOP-16 footprint are critical constraints. Verify that the single-ended input configuration aligns with the source signal characteristics, as differential inputs are not supported by this specific part number.

Analog To Digital Converters (ADC) Part Context

The ADS7229 belongs to Texas Instruments' family of low-power, high-speed ADCs designed for general-purpose data acquisition. It complements other devices in the series such as the ADS7230 and ADS7253, which offer varying resolutions and channel counts. This specific variant provides a balance between speed, accuracy, and power efficiency for embedded systems.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements within the same family include the ADS7229IPW. For higher resolution needs, consider the ADS7251 or ADS7253 series. Ensure compatibility with the existing SPI interface and power supply requirements when substituting with other SAR ADCs.
