Low-noise low-drift 38.4kSPS delta-sigma analog-to-digital converters

28-08-2015 | Mouser Electronics | Test & Measurement

Texas Instruments' ADS126x low-noise low-drift, 38.4kSPS analog-to-digital
delta-sigma (?S) converters are now stocked by Mouser. They come with an
integrated PGA, reference, and internal fault monitors.

The ADS1263 integrates an auxiliary, 24-bit, ?S ADC intended for background
measurements. These sensor-ready ADCs provide complete, high-accuracy,
one-chip measurement solutions for the most-demanding sensor applications.
This includes 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 ?S
modulator, followed by a programmable digital filter. The flexible analog
front-end (AFE) incorporates two sensor-excitation current sources suitable
for direct RTD measurement.
