Product Overview: Texas Instruments ADS1246IPW

The ADS1246IPW is a precision, low-noise, 24-bit, analog-to-digital converter (ADC) designed by Texas Instruments, a leader in semiconductor solutions. This high-performance ADC is ideal for a wide range of applications, including industrial data acquisition, medical instrumentation, and temperature sensing with RTDs, thermocouples, and thermistors.

With its ability to perform high-resolution measurements, the ADS1246IPW stands out for its impressive data acquisition capabilities. The device features an onboard, low-noise programmable gain amplifier (PGA), a precision delta-sigma (ΔΣ) modulator, and an oscillator. These integrated components contribute to the ADS1246IPW's ability to provide a complete front-end solution for sensor measurement.

The ADS1246IPW operates over a wide supply range of 2.7V to 5.25V and is specified for temperature ranges from -40°C to +85°C, ensuring reliable performance in diverse environments. The device also includes a flexible input multiplexer (MUX) that can be configured for single-ended or differential inputs, enabling it to accommodate various signal types.

Key features of the ADS1246IPW include:

• 24-bit resolution with no missing codes
• Low noise: 40 nVrms at 10 SPS
• Programmable data rates up to 2 kSPS
• Internal PGA with gains of 1 to 128
• Internal oscillator – no external components required
• Four single-ended or two differential inputs
• Current sources for sensor excitation
• SPI-compatible serial interface

The ADS1246IPW is available in a TSSOP-16 package, which is conducive for space-constrained applications. Its robust design and advanced features make it an excellent choice for engineers and designers seeking a high-quality ADC to integrate into their systems.
