It samples at 30 kSPS and accepts both differential and single-ended inputs through an input multiplexer that can handle up to 4 differential or 8 single-ended channels. The SPI data interface and external voltage reference architecture make it a straightforward fit for systems where the reference accuracy and drift are controlled by the board-level design. ## Supply rails and digital interface — what the 3.3 V logic means for your MCU The 28-SSOP package (0.209-inch body width) is a standard fine-pitch surface-mount footprint that routes comfortably on a two-layer board if the analog and digital grounds are split cleanly under the device.","metaTitle":"ADS1256IDBT 24-Bit Sigma-Delta ADC, 30 kSPS, PGA, SPI","metaDescription":"Texas Instruments ADS1256IDBT 24-bit Sigma-Delta ADC with PGA, 30 kSPS, SPI interface, 28-SSOP.
