- Auxiliary 24-bit, ΔΣ ADC (ADS1263)
- Data rates: 2.5 SPS to 38400 SPS
- Differential input, CMOS PGA
- 11 multifunction analog inputs
- High-accuracy architecture:
- Offset drift: 1 nV/°C
- Gain drift: 0.5 ppm/°C
- Noise: 7 nVRMS (2.5 SPS, gain = 32)
- Linearity: 3 ppm
- 2.5-V internal voltage reference:
- Temperature drift: 2 ppm/°C
- 50-Hz and 60-Hz rejection
- Single-cycle settled conversions
- Dual sensor excitation current sources
- Internal fault monitors
- Internal ADC test signal
- 8 general-purpose inputs/outputs
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.
