ADS7830IPWT

Analog To Digital Converters (ADC) Overview

The ADS7830IPWT is an 8-bit analog-to-digital converter (ADC) manufactured by Texas Instruments, housed in a TSSOP-16 surface-mount package. It features an I2C interface and supports up to 8 single-ended or differential input channels with a sampling rate of 70 kS/s. The device utilizes a Successive Approximation Register (SAR) architecture and operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. Key performance metrics include a signal-to-noise ratio (SNR) of 50 dB, differential nonlinearity (DNL) of ±0.5 LSB, and integral nonlinearity (INL) of ±0.5 LSB. It consumes 750 µW of power and includes an internal reference, functioning within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal voltage reference to eliminate the need for external components.
• Supports flexible input configurations with selectable single-ended or differential modes across multiple channels.
• Utilizes a standard I2C serial interface for simplified system connectivity.

Analog To Digital Converters (ADC) Applications

• Battery-powered sensor nodes requiring low static power consumption.
• Industrial IO modules for low-cost analog signal expansion.
• Motor drive boards for auxiliary current monitoring applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPWT corresponds to the TSSOP-16 package and reel/cut-tape availability through authorized distributors. Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure the I2C address configuration matches the target system design, as default settings may vary based on hardware pin states.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and moderate speed are sufficient for multi-channel acquisition. The integrated reference simplifies PCB layout compared to external reference designs. Consider the SAR architecture's deterministic timing for real-time control loops. Evaluate the 70 kS/s limit against the Nyquist requirements of the highest frequency input signal to prevent aliasing.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7830 series of low-power ADCs. It serves as a cost-effective solution for embedded systems where space is constrained. The device complements higher-performance ADCs by providing a compact option for less demanding measurement tasks. Its compatibility with standard microcontroller I2C peripherals facilitates rapid prototyping.
