The ADS1262 and ADS1263 (ADS126x) are
low-noise, low-drift, 38.4-kSPS, delta-sigma (ΔΣ) ADCs with an integrated PGA,
reference, and internal fault monitors. The ADS1263 integrates an auxiliary, 24-bit,
ΔΣ ADC intended for background measurements. The sensor-ready ADCs provide complete,
high-accuracy, one-chip measurement solutions for the most-demanding sensor
applications, including weigh scales, strain-gauge sensors, thermocouples, and
resistance temperature devices (RTD).
The ADCs are comprised of a low-noise,
CMOS PGA (gains 1 to 32), a ΔΣ modulator, followed by a programmable digital filter.
The flexible analog front-end (AFE) incorporates two sensor-excitation current
sources suitable for direct RTD measurement.
A single-cycle settling digital filter
maximizes multiple-input conversion throughput, while providing 130-dB rejection of
50-Hz and 60-Hz line cycle interference.
The ADS1262 and ADS1263 are pin and
functional compatible. These devices are available in a 28-pin TSSOP package and are
fully specified over the –40°C to +125°C temperature
range.
