Product details

24-bit sigma-delta ADC with integrated PGA — why it matters for precision measurements

The Texas Instruments ADS1256IDBTG4 is a 24-bit sigma-delta ADC that integrates a programmable gain amplifier (PGA) and an input multiplexer in a single 28-SSOP package. This architecture is designed for precision measurement applications where low noise and high resolution are critical, such as weigh scales, pressure transducers, and industrial process control. The MUX-PGA-ADC configuration allows the device to handle up to 4 differential or 8 single-ended inputs through the same signal chain.

30 kSPS sampling rate and supply rails

The ADC samples at 30 kSPS. An external voltage reference is required — the ADS1256 does not include an internal reference. The SPI data interface keeps the pin count low and is compatible with most microcontrollers.

Frequently asked questions

Where can I buy ADS1256IDBTG4 and how do I get a price?

Submit an RFQ for current availability and pricing — both are confirmed at quote time. No stock-holding claim is made; the part is quoted to order.

Does ADS1256IDBTG4 have an internal PGA?

Yes, the ADS1256IDBTG4 integrates a programmable gain amplifier (PGA) as part of its MUX-PGA-ADC architecture. This allows the device to amplify low-level sensor signals before conversion, reducing the need for external signal conditioning.
