ADS1203IPWRG4

Overview

The ADS1203IPWRG4 is a single-channel, 16-bit delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It integrates a programmable gain amplifier (PGA) with gains of 1, 2, 4, 8, 16, or 32, and an internal reference voltage. The device operates on a single 5V supply and features a serial interface compatible with standard SPI protocols. Key electrical specifications include a data rate of up to 40 kSPS, a differential input range of ±250 mV, and low power consumption. It is housed in a 16-pin VQFN package.

Feature Summary

• 16-bit resolution with 14-bit linearity
• Integrated PGA with gains from 1 to 32
• Internal precision reference voltage
• Single 5V supply operation

Applications

• Motor control current measurement
• Industrial process control
• Weight scales and load cells

Procurement Notes

Verify the G4 suffix indicates lead-free and RoHS-compliant construction per Texas Instruments standards. Confirm the IPWR package designation corresponds to the 16-pin VQFN (3x3 mm) form factor. Ensure compatibility with the required operating temperature range for the specific application environment.

Selection Notes

Select this component when high-resolution DC measurement is required with minimal external components. The integrated PGA reduces the need for external amplifiers, simplifying board layout. Verify that the 40 kSPS maximum data rate meets the system's throughput requirements.

Part Context

This part belongs to the ADS1203 family of delta-sigma ADCs designed for precision measurement applications. It serves as a direct replacement for older Burr-Brown branded versions, maintaining pinout and functional compatibility while adhering to modern environmental compliance standards.

Replacement Considerations

Check for ADS1203IPWR as a non-RoHS predecessor. For higher resolution needs, consider the ADS1220 series. For multi-channel applications, evaluate the ADS124S08.
