ADS7229IPW

Analog To Digital Converters (ADC) Overview

The ADS7229IPW is a low-power, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-channel single-ended input and operates with an analog supply voltage range of 2.7 V to 5.5 V and a digital I/O supply range of 1.65 V to 5.5 V. The device supports a sampling rate of 1 MSPS at 3 V and includes an internal oscillator. Key performance metrics include a signal-to-noise ratio (SNR) of 73.9 dB, differential nonlinearity (DNL) of ±0.5 LSB maximum, and integral nonlinearity (INL) of ±0.5 LSB maximum. It utilizes a serial SPI-compatible interface with SCLK up to 50 MHz and is housed in a TSSOP-16 package suitable for industrial temperature ranges from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Low power consumption of 13.7 mW at 1 MHz sampling rate
• Built-in conversion clock eliminates external clock requirements
• Supports daisy-chainable operation for multiple converters
• Comprehensive shutdown modes including deep sleep and auto-sleep

Analog To Digital Converters (ADC) Applications

• Data acquisition systems
• Industrial process control
• Medical devices
• Transducer interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix 'PW' corresponds to the TSSOP-16 tube packaging variant rather than the 'PWR' reel variant. Confirm RoHS compliance status through official documentation as indicated in distributor listings. Ensure the external reference voltage configuration matches system requirements since the device does not include an internal reference.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel 12-bit resolution is required with moderate speed up to 1 MSPS. It is suitable for applications needing low power dissipation and flexible supply voltages. Consider the ADS7230 if dual-channel multiplexing or programmable TAG bits are necessary instead of the single-channel ADS7229.

Analog To Digital Converters (ADC) Part Context

The ADS7229 belongs to the ADS7229/ADS7230 family of low-power SAR ADCs from Texas Instruments. It shares the same core architecture with the ADS7230 but differs in channel configuration and feature set. This series is designed for industrial and medical applications requiring high DC accuracy and low power consumption within a compact TSSOP-16 or QFN-16 package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7230 is a compatible alternative within the same family offering dual-channel inputs and additional programmability. Verify pin compatibility and software register differences when substituting.
