The ADS1260 and ADS1261 (ADS126x) are precision, 40-kSPS, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) that include a programmable gain amplifier (PGA). The devices also include a precision voltage reference and internal fault monitors. The sensor-ready ADCs give a high-accuracy, single-chip solution for the most demanding measurements, for example, weigh scales and resistance temperature detectors (RTDs).
The ADCs contain an input signal multiplexer, a low-noise PGA (with gains from 1 to 128), a 24-bit ΔΣ modulator, a precision voltage reference, and a programmable digital filter.
The high-impedance PGA inputs (1 GΩ) decrease measurement error due to sensor loading. The ADS1260 supports three differential or five single-ended inputs. The ADS1261 supports five differential or ten single-ended inputs. The integrated current sources simplify the measurement of RTDs.
The flexible digital filter is programmable for single-cycle settled conversions, while supplying simultaneous 50-Hz and 60-Hz line cycle rejection. Signal and reference monitors, a temperature sensor, and CRC data verification make data reliability better.
The ADS126x are pin compatible devices given in a 5-mm × 5-mm VQFN package and are specified across the –40°C to +125°C temperature range.
