Tiny 16-bit ADC Serves Portable Industrial And Consumer Applications

A family of 16-bit analog-to-digital converters (ADCs) comes packaged in a leadless QFN measuring 2.0 x 1.5 x 0.4 mm, which is 70% smaller than competing devices. In addition to significant system space savings, the ADS1115 family provides options for scalable integration to reduce component count and simplify design. This family supports 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, consuming just 150 µA (typical) and operating down to 2 V. The ADS1115 is the most highly integrated member of the family, incorporating an oscillator, low-drift reference, programmable gain amplifier, comparator, and four-channel input multiplexer into a tiny package. This family also includes 12-bit versions for increased flexibility. The ADS1115, ADS1114 and ADS1113 are available now. Pricing for the ADS1115 starts at $2.25 each in quantities of 1000. The ADS1114 starts at $2.00 and the ADS1113 starts at $1.85 in similar quantities. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
