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. Combined with a signal amplifier (such as the PGA280), a high-resolution, high-accuracy measurement system is formed that is capable of digitizing a wide range of signals.

The converter uses a fourth-order, inherently stable, delta-sigma (ΔΣ) modulator that provides outstanding noise and linearity performance. The data rates are programmable up to 14kSPS including 10SPS, 50SPS, and 60SPS that provide excellent normal mode line-cycle rejection. The digital filter can be programmed for a fast settling mode where the conversions settle in a single cycle, or programmed for a high line-cycle rejection mode.
