TI claims smallest 16-bit ADC

Dallas, Texas — Texas Instruments Inc.(TI) has introduced a family of 16-bit analog-to-digital converters (ADCs) packaged in a leadless QFN measuring 2.0 x 1.5 x 0.4 mm that the company claims is 70 percent smaller than the nearest competition.

In addition to the space savings, the ADS1115 family provides product options for scalable integration to reduce component count and simplify design, said TI. Applications include battery monitoring, portable instrumentation, industrial process control, smart transmitters, medical instrumentation and other industrial and consumer systems.


Designed for precision, power efficiency and ease of implementation, the ADS1115 family performs conversions at programmable data rates up to 860 samples per second (SPS), consuming 150 uA (typical) of supply current and operating down to 2 V. The ADS1115 is the most highly integrated member of the new family, incorporating an oscillator, low-drift reference, programmable gain amplifier, comparator and four-channel input multiplexer into a tiny package, said TI. This family also includes 12-bit versions for increased flexibility.

Customers can speed time-to-market with compatible TI devices, including amplifiers (OPA333, INA333), references (REF33xx), temperature sensors (TMP102) digital isolators (ISO721), digital-to-analog converters (DAC7731, DAC856x) and ultra-low-power microcontrollers (MSP430).

Pricing: The ADS1115 starts at $2.25 in quantities of 1,000; the ADS1114 starts at $2.00 and the ADS1113 starts at $1.85.
Availability: The ADS1115, ADS1114 and ADS1113 are available now from TI and its authorized distributors.
