Texas Instruments ADS101xL 12-Bit Delta-Sigma ADCs
Texas Instruments ADS101xL 12-Bit Delta-Sigma Analog-to-Digital Converters (ADCs) are precision, low-power, 12-bit, I2C-compatible ADCs offered in ultra-small, 12-pin DSBGA and 10-pin VSSOP packages. The ADS101xL incorporates a low-drift voltage reference and an oscillator. It also incorporates a programmable gain amplifier (PGA) and a digital comparator. These features, along with the device's wide operating supply range, are useful for power- and space-constrained sensor measurement applications.
The Texas Instruments ADS101xL performs conversions at data rates up to 3300 samples per second (SPS). The PGA offers input ranges from ±256mV to ±6.144V, allowing precise large- and small-signal measurements. The ADS1015L features an input multiplexer (MUX) that allows four single-ended or two differential input measurements. Use the digital comparator in the ADS101xL for under and overvoltage detection.
