ADS1210 and ADS1211 is precision, wide dynamic range, Δ-Σ analog digits operating with 24 bits of resolution from a single +5 V power converter. Differential input, ideal for direct connection to sensors or low-level signals. The delta-sigma architecture is used for wide dynamic range and guarantees 22-bit no-loss code performance. The effective resolution for 23 bits is achieved through a very low noise input amplifier conversion rate, used up to 10Hz. The effective resolution of 20 bits can be maintained to a sample rate of 1kHz using the unique modulator turbine mode of operation. The converter's further increased dynamic range provides a two-step programmable gain amplifier with low noise gains ranging from 1 to 16.
