The ADS1259 is a high-linearity, low-drift, 24-bit, analog-to-digital converter (ADC) designed for the needs of industrial process control, precision instrumentation, and other exacting applications.
The ADS1259 is a high‑linearity, 24‑bit analog‑to‑digital converter designed for industrial process control, precision instrumentation and test‑and‑measurement applications. It provides a selectable data‑rate from 10 SPS up to 14.4 kSPS and includes an integrated low‑noise 2.5 V reference.
Key features include a SPI‑compatible 4‑wire interface with checksum and redundant read capability, on‑chip oscillator or external clock options, low power consumption (13 mW active, <25 µW power‑down), and operation over a wide temperature range (‑40 °C to +125 °C). The device is supplied in a TSSOP‑20 package.
